Membrane technology processes for water treatment
Below, we quote the most used membrane processes:
- Microfiltration (MF)
- Ultrafiltration (UF)
- Nanofiltration (NF)
- Reverse Osmosis (RO)
- Electrodialysis (ED)
1st most used membrane process for the treatment of water with electrical potential
Electrodialysis membrane process
La electrodialysis It is the process that uses exchange membranes that allow ionic substances in solution to be separated by applying a potential difference, whose driving force is not pressure but of electric potential, and therefore the Membranes used in electrodialysis have groups with different electrical charges, specifically anionic and cationic...
In this way, it is used in many countries as an alternative to separate, concentrate and purify substances.
2nd Membrane process by pressure gradient
Membrane process for water treatment Microfiltration
What is the separation technique with microfiltration membrane?
The principle of microfiltration is a physical separation process in which the size of a membrane's pores determines the extent to which dissolved solids, turbidity and microorganisms are removed. Substances larger than the membrane pores are completely retained.
What are microfiltration membranes like?
Specifically, the membranes microfiltration They have a pore size that allows separating particle sizes of different nature (suspended solids, fine particles, colloids, algae and microorganisms such as bacteria) within the Range: 0.1 μm – 10 μm,
What are microfiltration membranes used for?
Microfiltration is used for cold sterilization of liquid foods and pharmaceuticals, for the reduction of microorganisms from water, and is common as water pretreatment for nanofiltration and reverse osmosis.
3rd pressure gradient membrane process
Membrane process for water treatment Ultrafiltration
What is the ultrafiltration membrane process like?
La ultrafiltration (UF) is a process porion separation membrane, within the technology of membranes for water treatment, which allows the mechanical separation of suspended or dissolved solids through a sieve, using hydrostatic pressure to force water through a membrane semipermeable.
What are ultrafiltration membranes like?
- The membranes of ultrafiltration are generally porous membranes.
- Also I know classified by molecular cutoff weight, which is equivalent to the molecular weight of the smallest molecule that its pores can retain at 90%, and that ranges from 1.000 to 500.000, that is, molecules and macromolecules.
- On the other hand, the pore size that allows separating particle sizes of different nature from those of ultrafiltration membranes is usually between 0,04 and 0,1 μm.
What are ultrafiltration membranes used for?
- For its part, ultrafiltration is applied for the elimination of organic substances, in the elimination of trihalomethanes from water, in the treatment of wastewater and in the textile industry.
Differences between the principle of microfiltration and ultrafiltration membranes for water treatment
The main difference between microfiltration membranes and ultrafiltration is the pore size.
- On the one hand, we have microfiltration and ultrafiltration that allows the mechanical separation of suspended or dissolved solids using a sieve.
- The main difference between both processes is the pore size of the membrane, which determines which solutes can be removed in the filtration process.
- Substances larger than the membrane pores are completely retained, and even some substances smaller than the pores may also be partially or totally retained depending on the selectivity of the membrane.
- In addition to the influence of pore size, The distribution of these in the membrane structure is also important in both processes..
- Microfiltration is capable of separating small particles and ultrafiltration macromolecules.
- Besides, the productivity of both processes is highAlthough the permeability is greater in microfiltration membranes and the working pressures of this process are also the lowest, ultrafiltration is also characterized by quite low required pressure differences, since there are hardly any osmotic differences.
4nd Membrane process by pressure gradient
Nanofiltration membrane processes
What are Nanofiltration membrane processes?
La nanofiltration membranes They have a microporous structure and can retain particles with a size of 0,1 nm-0,001 µm, which allows most molecules to be separated from water, although those of lower molecular weight are retained in the membrane partially.
La Nanofiltration is an intermediate process between reverse osmosis and ultrafiltration due to the levels of separation it allows and the application pressures it requires.
What is the Nanofiltration membrane like?
La Nanofiltration membranes are microporous in structure and can retain particles with a size of 0,1 nm-0,001 µm, which allows the majority of molecules to be separated from water, although those of lower molecular weight are partially retained in the membrane. So this process It allows the separation of organic substances (proteins, sugars), microorganisms and some multivalent salts.
How the Nanofiltration membrane process is carried out
Furthermore, in this process The separation of substances is carried out in a combined manner both by the size of the pores and by the dissolution-diffusion mechanisms. that characterize the reverse osmosis process and that we explain in more depth in the next point.
What is Nanofiltration used for?
Nanofiltration is used for removal of heavy metals from wastewater, for wastewater decontamination, for nitrate removal, for color removal and also as pretreatment before reverse osmosis.
5nd Membrane process by pressure gradient
Membrane technology processes for reverse osmosis water treatment
What is the membrane process for reverse osmosis water treatment?
- This membrane process retains virtually all smaller particle and salt molecules, including monovalent salts, while water molecules can pass freely through the membrane.
What is the filtration process like with reverse osmosis membranes?
- The main characteristic of this process is that with reverse osmosis membranes the rejection of solutes does not occur through filtration, but rather that the characteristic transport mechanism is that of dissolution-diffusion across the membrane
- That is to say, the separation process is due to the different solubility and diffusivity in the membrane of the different components of the aqueous solution and therefore it is a physical-chemical process, since the interactions that exist between the water molecules, the membrane and the solutes are responsible for the separation.
Membrane properties for water treatment by reverse osmosis
- RO membranes are hydrophilic so that water molecules are easily attracted and transported through the polymeric structure of the membrane by diffusion.
- Therefore the components that constitute the permeate, that is, those that manage to cross the membrane, they must have certain affinity with the membrane material since it is a decisive factor so that they can dissolve in its structure and subsequently diffuse through it.
- Hence, in reverse osmosis it charges a lot membrane material is more important than in microfiltration and ultrafiltration processes.
- Also reverse osmosis membranes are dense and non-porous, present some lower permeability values, having to work at higher pressure values that allow the osmotic pressure to be overcome to achieve a reasonable flow of fluid from the concentrated phase to the permeate.
Reverse osmosis is the technique most widely used today for water desalination.
- , since it allows the elimination of salts, as well as low molecular weight organic compounds, allowing the production of high quality drinking water.
What is Reverse Osmosis Water Treatment?
What does osmosis mean?
Meaning of the word osmosis
First of all, mention that Osmosis is a word of Greek origin that means “pushing action.”.
Osmosis is defined as a passive diffusion, characterized by the passage of water, a solvent, through the semipermeable membrane, from the most dilute solution to the most concentrated one.
Osmotic pressure meaning
And we understand by osmotic pressure, the pressure that would be necessary to stop the flow of water through the semipermeable membrane.
What is osmosis and diffusion?
Osmosis and diffusion what is it
La diffusion involves the movement of particles from an area of high concentration to an area of low concentration. The osmosis It's a special kind of diffusion. The osmosis is diffusion of water particles through a membrane.
What is an osmosis system
Explanation of water treatment with osmosis
La osmosis is a water treatment system that achieves remove all contaminants present in the water leaving a neutral flavor and exceptional quality for consumption. Furthermore, the water treated with this type of system has minimal levels of microorganisms.
Differences between reverse osmosis and direct osmosis water treatment
Types of osmosis: reverse osmosis for water treatment and direct osmosis
Osmosis (O) and water treatment by reverse osmosis (RO) are two phenomena that occur naturally inside living beings.
For example, through osmosis the cells of our body, which are surrounded by a semipermeable membrane, allow the passage of nutrients into and out of the cell, thus favoring both the incorporation of nutrients necessary for cellular metabolism and the expulsion of nutrients. waste thereof.
Types of osmosis
- This physical-chemical phenomenon can be classified into two types or forms of osmosis: direct and reverse, which differ greatly in their origin and operation.
What is reverse osmosis for water treatment: water purification technology
Reverse osmosis for water treatment is an inverted process of the natural phenomenon
So, as its name indicates, Reverse osmosis treatment for water is an inverted process of the natural phenomenon, which is produced artificially by man and manages to pass the water from the side with the highest concentration of solute to the side with the lowest.
Reverse osmosis water treatment is a water purification technology that uses a semipermeable membrane to remove ions, molecules and larger particles in drinking water.
The reverse osmosis membrane is the same as that of cells and serves to eliminate ions, molecules and larger particles in water or other types of solutions.
Thus, reverse osmosis for water treatment is a sophisticated water treatment process that has been used in industrial plants for quite some time.
This purification technology uses a semi-permeable membrane to remove ions, molecules and larger particles in drinking water.
Finally, mention that to achieve reverse osmosis, pressure is applied to overcome the osmotic pressure.
What is direct osmosis: natural process
What is direct osmosis?
- Direct osmosis is a natural process in which it is not necessary to apply high pressures, so the expected energy cost is lower than that of water treated by reverse osmosis. It stands out for being applied in wastewater treatments, water desalination and water purification.
Differences between reverse osmosis for water treatment and direct osmosis
Unlike reverse osmosis water treatment, forward osmosis has higher product recovery and requires less hydraulic pressure.
For example, forward osmosis plants use the osmotic pressure gradient to cause the diffusion of water through a semipermeable membrane from a dilute solution to a highly concentrated one.
Through this process, the extracting solution is diluted, thus reducing its osmotic pressure until it becomes equal to the feed pressure.

What is reverse osmosis system?
Reverse osmosis water treatment explanation
Reverse osmosis water treatment definition
Reverse osmosis is a water purification technology that uses a semi-permeable membrane to remove ions, molecules and larger particles in drinking water.
What is the reverse osmosis process for water treatment?
Osmosis is a natural phenomenon
To begin with, mention that the reverse osmosis device (water osmotizer) is a natural phenomenon, rather a physical process, through which water passes through a battery of filters and a semipermeable membrane that separates two solutions. aqueous of different concentrationsn, that is, it seeks balance in the presence of two fluids with different concentrations of dissolved solids, which will manage to mix when the concentration is uniform.
What is the basis of reverse osmosis water treatment?
Reverse osmosis foundation
Broadly speaking, this is the basic foundation of water treated by reverse osmosis, which constitutes a mature technology that desalts at the lowest energy cost per cubic meter of water at present and that requires only electrical power for its funtionability.
What is the principle of reverse osmosis?
Basic principle of reverse osmosis water treatment
On many occasions we have heard aboutreverse osmosis treatment for water and its importance in the water desalination process, but what does this process consist of and what is its origin.
Reverse Osmosis consists of separating one component from another in a solution, through the forces exerted on a semi-permeable membrane. Its name comes from "osmosis", the natural phenomenon by which plant and animal cells are supplied with water to maintain life.
What is the reverse osmosis treated water process?
What phenomenon occurs in the osmosis system?
La osmosis It is the phenomenon that occurs when two solutions with different concentrations are separated by a semipermeable membrane and the solvent diffuses through the membrane from the liquid of lower concentration to the liquid of higher concentration until the concentrations balance. This phenomenon occurs from spontaneously without energy expenditure and therefore it is a phenomenon of passive diffusion.
In other words, if, for example, we had two solutions of water and salt separated by a semipermeable membrane (that is, one that only allows water to pass through); water would move from the solution of lower concentration to the one of higher concentration without the need to provide energy thanks to the phenomenon of osmosis.
Aqueous media can have different concentrations of one or more solutes.
The concentration of solvents and solutes (for example, water would be the solvent and salt the solute in the example above) allows classify aqueous media by comparison with respect to another in:
- Hypotonic: refers to the solution in which the solute has a lower concentration outside compared to the interior environment of the cell.
- Hypertonic: It is the opposite of the previous solution, that is, the solute has a higher concentration in the external medium.
- Isotonic: It is a balanced solution where there is the same concentration of solute in the external and internal medium.
What is osmotic pressure
The pressure exerted by the solvent (water) on the side of the membrane where there is a lower concentration towards the compartment with a higher concentration is called osmotic pressure.
Continuing with the previous terminology, the pressure produced on the side of the membrane from the hypotonic medium to the hypertonic medium is the osmotic pressure.
Osmotic pressure occurs naturally and spontaneously.
Let's take a container as an example and divide it with a semipermeable membrane or barrier so that there is no communication between the two parts of the container.
Now let's put distilled water on one side of the membrane and on the other, water with some Soluto dissolved, (salt, sugar, etc.) so that both are at the same level.
After some time, we will observe that the level in the container of the distilled water has fallen by the same amount as the level of the container with salt has risen (figure b) due to the exclusive passage of water through the membrane.
This difference in height generates a pressure difference It is known as osmotic pressure and it takes place naturally and spontaneously.
How does reverse osmosis equipment work?
What is a reverse osmosis unit?
Systems reverse osmosis for water treatment They work by taking advantage of the different osmotic pressures on both sides of a membrane.
First of all, say that it is a innovative machine in the market. This machine has several filters, one sediment filter that eliminates turbidity from the water completely and two active carbon filters. These filters are responsible for eliminating chlorine, suspended particles and their derivatives, as well as other organic substances.
Water purification method using reverse osmosis equipment
reverse osmosis It is a method of water purification by which it is forced to pass through a semipermeable membrane, from a more concentrated solution (dissolved salts, chlorine, contaminants) to a less concentrated or pure solution. This entire process is done by applying pressure.
A semipermeable membrane is a filter with small pores that blocks contaminants but allows water molecules to pass through.
When pressure forces water through the semipermeable membrane, water flows from the more concentrated side (with more contaminants) to the less concentrated side (with fewer contaminants). leaving impurities behind and providing pure water.
Although the semipermeable membrane is the heart of the system, reverse osmosis equipment has several phases depending on the number of pre-filters and post-filters, and the water can pass through between 3 and 7 different stages before coming out of the tap for consumption (we will talk about this later).
The filters are called pre-filters or post-filters depending on whether the water passes through them before or after passing through the membrane. Next, we explain the operation of a basic four-stage equipment.
Water osmotizer filtration process
The filtration process in a conventional five-stage equipment
- 1# The water passes through a sediment filter that eliminates dirt, algae, rust and in general everything above a size of 5 microns.
- 2# The water passes through a granular activated carbon filter, which removes chlorine, heavy metals, dioxins, toxins and odors by adsorption.
- 3# The water passes through a second activated carbon filter that finishes eliminating chlorine, heavy metals, dioxins and odors by adsorption, protecting the membrane from small particles.
- 4# The water passes through the heart of the equipment: the semipermeable membrane, where up to 95% of dissolved particles are removed, even those that are small enough to be seen with a microscope.
- 5# Finally, the water passes through a coconut charcoal post-filter that regulates its flavor and gives it a balanced pH.
How much water does reverse osmosis filter?
Reverse osmosis membranes have the characteristics of continuous cleaning while they work, because if not, they would suffer an accumulation of contaminants and saturation in a short time, so part of the incoming water flow drags contaminants such as salts and minerals.
This is known as reject water, which is commonly 40% product water and 60% reject water, in equipment with relatively good quality water, it can be 50%.
What reverse osmosis equipment eliminates
What minerals does reverse osmosis remove?
osmosis water does NOT have minerals
Therefore, the osmosis water system does NOT have minerals, since it eliminates contaminants from the water such as minerals, such asL: including nitrates, sulfates, fluoride, arsenic and many others.
Even if, The reverse osmosis device also does not allow healthy minerals such as magnesium, calcium, potassium or sodium to pass through.
It should be noted that it is important to verify their effectiveness in domestic use, since not all reverse osmosis filters filter the same or with the same efficiency.
For example, Reverse osmosis alone does not remove chlorine or soften water, and therefore this type of technology is usually used in filters in combination with activated carbon. Activated carbon also helps remove more than 70 additional contaminants, such as pesticides and heavy metals.
What contaminants does reverse osmosis equipment eliminate?
With prefilters you eliminate sediment, algae, dirt, chlorine, bad taste and odors. Through the semipermeable membrane, the dissolved solids such as arsenic and fluoride.
Reverse osmosis significantly reduces some of the most dangerous impurities such as: Lead, Mercury, Chromium-6, Chlorine, Chloramine and Sediment. It should be noted that, in the case of sediment, the higher the level of sediment in drinking water, the greater the chances of consumers developing gastrointestinal diseases. In the case of Mercury, too much of this element in the body damages the brain, kidneys, or even a developing fetus.
It is true that beneficial minerals such as calcium and magnesium are also largely eliminated, but the reality is that food is the main source of essential nutrients, not water. You would have to drink excessive amounts for your body to absorb enough mineral content through this means.
In any case, most multi-stage reverse osmosis equipment includes a phase in which the appropriate amount of minerals are returned to the water.
It should be noted that filter options other than reverse osmosis can help with taste and smell, but few reduce the most dangerous and invisible contaminants.
reverse osmosis heavy metals
By way of clarification, the purpose of reverse osmosis equipment is to filter contaminants such as: heavy metals, excess salts, microorganisms, toxic substances, etc.
But if the fluids are separated by a permeable membrane, only the one with the lowest concentration will move. Over a period of time the water content will be greater on one side of the membrane.
The difference in height between both fluids is what is known as osmotic pressure.
The most complete equipment also includes a UV lamp
In addition, The most complete equipment also includes a UV lamp which allows the water to be sterilized, thus eliminating living organisms and viruses. Although if the water you are going to purify comes from a drinking water treatment plant, it should already be microbiologically safe.
Direct osmosis what is it
What is direct osmosis
Direct osmosis what is it
Direct osmosis is a natural process in which it is not necessary to apply high pressures, so the expected energy cost is lower than that of reverse osmosis..
It stands out for being applied in wastewater treatments, water desalination and water purification.
Why osmosis is vital in cellular metabolism
Importance of osmosis
Osmosis is vital for cellular metabolism, since It is a form of transport of matter between the inside and outside of the cell that does not entail any energy expenditure, that is, it is produced passively, without consuming ATP.
In addition, this principle is also fundamental to explain the origin of life, given that in the first forms of cellular life there would not yet be active metabolic mechanisms.
Simple diffusion: process similar to osmosis
A process similar to osmosis is known as simple diffusion, from the point of view in which it involves the transit of particles from one medium (such as the cell interior) to another (such as the extracellular environment) through a semipermeable membrane, moving from the medium of higher concentration to the medium of lower concentration (that is, following the concentration gradient).
This takes place passively, that is, without additional energy consumption.
biological diffusion
What is biological diffusion
According to this, biological diffusion is what takes place in cells, allowing the entry or exit of molecules through the plasma membrane, according to the concentration gradient.
This is how, for example, oxygen enters the blood into the red blood cells, where hemoglobin can capture them for transport. This single example denotes the vital importance of this mechanism for life.
How biological diffusion originates
- To begin with, diffusion is the net flow of molecules from a region of high concentration to a region of low concentration.
- This difference in the concentration of a substance in space is called concentration gradient.
- Diffusion is due to the random movement of particles.
- All moving objects have kinetic energy or energy of motion.
- Particles of matter move in straight lines until they collide with other particles.
- After colliding, the particles soften, moving in a straight line until the next collision.
- There is no loss of energy.
- Diffusion will continue until there is no concentration gradient.
What is direct osmosis in living beings?
Osmosis in living beings what is it
La osmosis It is a fundamental biological process for the cellular metabolism of living beings, since for the survival of the cells and their proper functioning it is necessary to maintain the osmotic balance.
.
Natural or direct osmosis is the most common in nature,
since semipermeable membranes are part of the vast majority of organisms (for example plant roots, organs of our own body, cell membranes, etc.)
What is natural or direct osmosis?
It consists of eliminating any contaminant, chemical or biological, and altering the concentrations of different salts to achieve the necessary result. It would be ideal for the base water to be used for the production of beer to have a low mineral content, which allows it to be easily treated and thus obtain the perfect water for any style of beer you wish to make.
For that, An effective solution is the reverse osmosis water treatment system, since through this you can have ion-free practical water..
Osmotic balance
Fundamental process of direct osmosis in living beings
In living beings, osmosis is a ground process since for the survival of cells it is essential to maintain what is called the osmotic balance necessary for the cell to perform its functions
Osmosis is a process that affects both internally and externally.
Externally, it is very important for living beings that are exposed to environments with salinity and high osmotic pressure, such as those that live in the ocean or in salt marshes.
For this reason, living beings have developed osmoregulation systems that allow them to live in different environments, from the most extreme to the least aggressive in this regard.
This occurs naturally in the cells of all living beings, with the objective of purifying water extracted from the environment.
In other words, it works as a filter for contaminants and external agents that could alter or damage the body; An example of them is salinity and osmotic pressure.
What is direct osmosis in the animal cell
What is direct osmosis in the animal cell?
Cell membranes are semipermeable so osmosis is a phenomenon that occurs naturally.
Cases of osmoregulation mechanisms
Thus, if animals do not have mechanisms to adequately balance the concentration in the cells, two phenomena can occur due to osmotic pressure:
Osmoregulation mechanisms: crenation
- Crenation: is that which originates when the cell is in a hypertonic aqueous medium; and the water tends to come out. This can lead to dehydration, which can lead to cell death. .
Osmoregulation mechanisms: cytolysis
- Cytolysis: occurs when the cell is in a hypotonic solution; and tends to absorb water to reach isotonic equilibrium; In this case the cell can burst, giving rise to cytolysis.
Osmosis in the plant cell
What is osmosis like in the plant cell?
What is osmosis like in the plant cell?
La plant cell membrane It is the same as the previous one with respect to the origin (natural) and operation (achieving balance with the passage of water in an isotonic aqueous medium).
Examples of direct osmosis processes in living beings
Once you understand the How does direct osmosis work? in both cells, some examples of the process carried out in living beings are:
- Plants take water from their roots and the soil.
- Desalination plants separate water from salt. Passing it through a membrane that allows water and salt molecules to pass through.
- The large intestine takes in water through the epithelial cells. Thus allowing the passage of water molecules, but not waste material.
- When you sweat, water leaves the skin through this process.
Direct osmosis problems in the plant cell
Like animal cell membranes, plant membranes are also semipermeable.
In this case, the passage of water by osmosis tends to balance the cell towards an isotonic medium.
Due to this, two phenomena can also occur: plasmolysis or turgor.
Plasmolysis: direct osmosis setback in the plant cell
- Plasmolysis: occurs when in a hypertonic medium, water leaves the cell through the cell membrane, which can cause the membrane to detach.
- Furthermore, as the plasma membrane can detach from the plant wall, plasmolysis can occur and lead to incipient plasmolysis that is reversible or to an irreversible state.
Turgor: 2 direct osmosis setbacks in the plant cell
- Turgor: occurs when there is a hypotonic medium and the cell is responsible for filling its vacuoles through the absorption of water.
- It occurs when, in the presence of a hypotonic medium, the plant cell absorbs water, filling its vacuoles.

Who invented reverse osmosis water treatment?
History of the reverse osmosis water treatment process
France 1748 Jean Antoine Nollet: discovered that water spontaneously diffused through a pig bladder membrane
- The first investigations and the first studies on the phenomenon ofl reverse osmosis treatment for water They were made by Jean Antoine Nollet, a French scientist.
- In 1748 he discovered that water diffused spontaneously through a pig's bladder membrane, but he was not able to explain the reason for this phenomenon.
1840 Henri Dutrochet: discovers the phenomenon of osmotic pressure
- It states that the diffusion of the solvent through a semipermeable membrane always occurred from the solution with the lowest concentration of a solute to the solution with the highest concentration.
- In addition, the flowing solvent is capable of developing pressure on the membrane, this phenomenon called osmotic pressure.
1953: Charles E. Reid – Poses reverse osmosis water treatment
- The first to carry out the reverse osmosis process to obtain drinking water from sea water was Charles E. Reid in 1953, which was submitted to the consideration of the US Office of Saline Waters, but the lack of a suitable membrane to efficiently carry out water treatment by reverse osmosis
1959: Reid and EJ Breton – Cellulose acetate membrane discovery
- Then, the solution to the problem of obtaining pure water from sea or brackish water was solved by the discovery of the cellulose acetate membrane by Reid himself and EJ Breton in 1959.
1960-1962S. Loeb and S. Sourirajan – Rei membrane proven to progress with solvent flow
- In the sixties it was Sydney Loeb and Srinivasa Sourirajan who created an asymmetric cellulose membrane that improved on the previous membrane created by Reid and Brenton.
- Thus, it was demonstrated that the Reid and Breton membrane considerably improved solvent flux and salt rejection if the membrane was made asymmetric instead of homogeneous.
- Next, it is detected through investigations with the electron microscope that the asymmetry in the Loeb and Sourirajan membrane is based on the presence of a thin film of polymer in an amorphous phase with crystalline divisions on the surface of the membrane.
- In view of which it can be stated that this film is the active part of the membrane and responsible for the exclusion of solutes.
Reverse osmosis pool
What advantages does purifying water with the reverse osmosis system bring to the pool?
Why opt for a reverse osmosis water purification system?
Why choose reverse osmosis water treatment?
On the one hand, it should be noted that the great advantage of this water purification system is that When installed it can also be used for domestic use, eliminating bad odors and bad taste that tap water can have. By achieving crystal clear water, there will never be cloudy water again.
At the same time, you will also have ideal water for the pool and avoid the expense of buying bottled water, as it guarantees safe use of water.
On the other hand, it is equally important to highlight that reverse osmosis with its water filtration process that is It reduces water salts by 90% thanks to its semipermeable membranes.
So, the vast majority of people install, in addition to the pool service, a consumption point to have drinking water and use it for cooking in order to take care of their health in an easy and inexhaustible way.
This water purification system benefits people who suffer from diseases such as kidney stones. Apart from the quality of the water, it allows us to prevent the vast majority of diseases.
Finally, emphasize that it is a great alternative to preserve the quality of pool water and additionally have high quality pure water that can be used to meet different needs.
Benefits of reverse osmosis systems
What is reverse osmosis for pool water treatment?
Below, we summarize the contributions of using reverse osmosis, one of the most reliable systems:
- First of all, it should be noted that The reverse osmosis system is fully automated.
- Secondarily, mention that The maintenance and attention to be received is simple and scarce, since it is only based on the replacement of filters.
- Thirdly, another point in favor is that The reverse osmosis device is small in size, so it does not require large spaces.
- On the other hand, the process derived fromInstallation of the reverse osmosis system is very simple.
- Likewise, it is friendly to the environment, it does not require or expel any chemical products and it also does not need large quantities of water for its operation.
- Reverse osmosis devices produce good quality drinking water without taste or odor, since it retains most of the contaminants and for that reason reduces the risk of contracting diseases of any type, highlighting the gastrointestinal ones associated with bacteria.
- Finally, with the reverse osmosis treatment You will greatly reduce expenses in relation to pool chemicals, bottles of drinking water and at the same time the useful life of the piping and machinery system will be extended., thanks to the extraction of minerals that cause oxidation or obstruction in the pathways.
4 Myths of Domestic Reverse Osmosis
In 2 months or so, you would begin to recover your investment with your osmosis if you stop drinking from plastic bottles. In addition, you reduce pollution and drink more distilled water free of toxins.
Disadvantages of reverse osmosis filtration system
Osmosis water treatment equipment with incorrect flow is the main error
Truly, reverse osmosis water treatment has more advantages than disadvantages.
Although there are more advantages than disadvantages to reverse osmosis, in reality, the important thing is to find the one that provides the flow you need.
Cons of osmosis water treatment
Negative points of reverse osmosis water treatment
The problems that we can encounter with reverse osmosis equipment are:
- To start, This process demineralizes the water, also extracting the healthy minerals that naturally exist in water such as calcium or magnesium and for this reason it is recommended to have a remineralizing filter (in the next point we develop the concept).
- Generally, the reverse osmosis device has a short lifespan of the equipment itself.
- The filters sIf they are not replaced in the appropriate time, they can become clogged and damage the reverse osmosis membrane.
- This process can be a little slow, since it requires water pressure to purify.
- To conclude, you are going to have considerable water losses down the drain, that is, during the process a quantity of water will be lost down the drain.
How much water does reverse osmosis waste?
The rejection/product ratio can vary from 2 to 1 (2 liters of water to the drain for 1 liter of water produced) up to 12 to 1, depending on the quality of the product, the working pressure and the characteristics of the water to treat
How much water does reverse osmosis throw away?
This video shows the amount of water that a domestic reverse osmosis device throws down the drain for each liter of purified water it filters.

Pros and cons of bottled water
Advantages of bottled water
Bottled water can have advantages for consumption, for example, waters with very weak mineralization have less dry residue and, therefore, fewer minerals, which is why it can be good for a person with kidney problems. Additionally, consumers can choose between strong, weak or very weak mineralization. Their flavor is also more neutral than tap water, which is why they are indicated when preparing coffees or infusions.
Disadvantages of bottled water
Its drawbacks are rather practical: its acquisition for daily consumption represents a significant investment of time and money. In addition to the ecological cost: bottles are usually made with plastics derived from petroleum, which are polluting or will entail a new cost in recycling. A factor to which is added the energy consumption when extracting the water, treating it and transporting it to the points of sale.
Reverse osmosis drinking water
Advantages of consuming drinking water with Water Osmosis
What Reverse Osmosis Water Treatment Means for Drinking Water
Reverse osmosis water treatment of drinking water
Thanks to the osmosis of water, not only is the taste of water much better, greatly reducing salts, OC and THM, also when cooking foods retain their flavors and properties, including infusions and coffee.
We can use the water to irrigate plants as well as animals and aquariums.
Another use that we can give to this water is ideal for household appliances such as irons, robot vacuum cleaners, avoiding problems with limescale, oxidation, stains on surfaces, among others. If osmotized water is used throughout the house, for example in the shower, we will notice less itching on the skin as well as less irritation.
Another advantage of water osmosis is that it is easy to install as well as fast with the Idrania reverse osmosis system.
Advantages of reverse osmosis water treatment
1st benefit of osmosis drinking water: It is healthy
Drink osmotized water who
According to hundreds of studies around the world, Tap water that follows the drinking water regulations set by the World Health Organization (the US and the countries of the European Union follow these standards) is just as healthy as bottled water.
According to the WHO, tap water should have a mineralization level of less than 100 parts per million. However, in some areas of Spain - mainly in the Mediterranean basin - it is normal for this indicator to exceed the figure. Reverse osmosis equipment has a osmosis filter system that eliminate and separate from microparticles that are visible to the human eye to metal ions, of the ionic range, which are smaller than molecules and bacteria such as yeasts, fungi and viruses. In addition, these osmosis systems also respond to the presence of microplastics in water.
Mains water is analyzed numerous times a day to ensure that it is safe for consumption and, if it is not, the municipal water company is obliged to inform consumers of the incidents.
Osmosis water health
But, in reality, health level It cannot be said that it is better or worse than any bottled or tap water.. An older adult may need the minerals contained in the water to help strengthen their muscle and bone structure, or on the contrary, osmosis water may be the one that suits them best because, being of very low mineralization, it increases the diuretic properties characteristic of the water itself
2nd benefit of osmosis drinking water: Savings of money compared to mineral water
Osmosis water for drinking helps not waste
- Although, obviously, the savings will depend on what you spend on the device and what the spare parts and revisions cost you.
- Therefore, with the simple gesture of drinking tap water at home and always carrying a reusable bottle with you, you can save a lot of money, up to €550 per year.
- A water filter also helps save a considerable sum of money in the home economy.
3rd benefit of osmosis drinking water: Gain in comfort
Savings on trips to the supermarket and transportation
There is no doubt about this, if you don't buy mineral water, you don't have to transport it.
- The tap is an unlimited source of water, whenever you need it, whether for drinking, cooking, making coffee or tea, watering your pet or watering your plants.
- If you use the tap, you don't have to buy, carry or throw away plastic bottles to do all these activities.
4th benefit of osmosis drinking water: Good taste
Drinking water treatment with reverse osmosis system: Improved flavor
- In some cities, tap water tastes good. However, water sometimes has an unpleasant taste, which is easily eliminated through the use of water filters.
- In hard water, that is, water that has many dissolved salts, mainly calcium (which becomes encrusted) and magnesium, the presence of chlorine makes it have that characteristic flavor, it is a combination of the two characteristics. That's why filter jugs improve the flavor.
- There are blind tests that show, 9 out of 10 people do not notice the difference between filtered water and bottled water.
- And for those who buy bottles because they prefer sparkling water, there is now a market for soda machines that can satisfy you.
Sodastream soda machine
What is the Sodastream device
SodaStream is a device for preparing homemade carbonated soft drinks following the principles of the invention that Guy Gilbey built in 1903.
The device allows users to carbonate drinking water to create soda.
5th benefit of treating drinking water with osmosis: You take care of the environment
Reduce the generation of plastics by not buying bottled water
- Certainly, there is a great carbon footprint associated with bottled water, with some reports estimating around 82,8 grams of CO2 per half-liter bottle.
- On the other hand, with tap water, the environmental impact is close to zero, except for the water used and purification activities.
Disadvantages of osmosis for drinking water
1st against osmosis to drink water: Waste of water
When passing through the osmosis filter, not all the water passes through the membrane. A separate part will be filtered, with a very low concentration of minerals, which is what you will drink, and another part where all the minerals have remained, therefore more concentrated, will be thrown down the drain. Although manufacturers tell you about proportions of 1 to 4 (four liters discarded for each liter filtered), the figure is usually much higher, this is only the optimal and is not so easily achieved. Figures from 1 to 10 are quite normal and if the equipment is not well chosen and the network pressure is not adequate, this figure can be multiplied by two or three.
But since that water goes directly to the drain you don't notice it, and since tap water is cheap you don't notice it on the bill. The pity is that with such low efficiency figures, the water you are throwing away is practically as good as that from the tap.
2nd disadvantage of osmosis water for drinkingDanger due to poor maintenance
If the device is not well maintained and the filters are changed when necessary, not only will they not filter well, but the quality of the water will worsen. And monitoring the performance and condition of the filters is not an easy task. In city water treatment plants, it is done by experts with many years of experience, in this case you have to do it yourself. And it doesn't make much sense that your manufacturer's recommendations apply to you, when the composition of tap water is different in each place. You don't have to be alarmist but you have to be careful.
3rd drawback osmosis drinking water low pH
By eliminating salts we reduce the pH of the water, which could corrode metals such as faucets or pots, incorporating that metal into the water. The pH can drop below the limits of drinkability.
What pH does osmosis water have?
El water osmosis has a pH approximately 6,5.
4th drawback of reverse osmosis purified water system: low popularity
for snobbery
We only have to look at the type of advertising that bottled water does to see sculptural bodies, with which they convey the idea that drinking bottled water is synonymous with being healthy and beautiful. For this reason, many people look towards the models that appear on television and, as happens with other products, they buy them by emulation. Brands compete in this type of advertising and an important factor to take into account is that we do not have to look for a relationship between advertising and quality since they do not always go hand in hand. Taking a look at the label that talks about the composition of the water can clear up any doubts, although some basic knowledge about water is needed to be able to properly interpret the labeling.

How does a domestic reverse osmosis unit work?
Operation reverse osmosis system:
- The water entering the equipment is pre-filtered to eliminate suspended solids, in order to protect the membrane and the pressure pump.
- Subsequently, it is driven by the high pressure pump to the activated carbon filters, this eliminates free chlorine that damages the membranes as well as eliminating components that are adsorbed by the activated carbon such as organic compounds.
- The membrane that receives this water, partitions into two different volumes, one of permeate (smaller volume) that contains approximately a total of dissolved solids of 10% of the original water, which is housed in the hydropneumatic type storage tank ( not in contact with the environment) this allows it to be collected safely for dispensing, and as it is under pressure, its extraction is quick and comfortable.
- The other portion of water corresponding to the rejection is discarded; it contains the ions that were retained by the membrane, with a content of total dissolved solids higher than the feed water. This volume is higher than the permeate volume due to design conditions, allowing the membrane surface to be cleaned continuously during the osmosis process, avoiding clogging.
- Prior to dispensing, the osmisis water passes through a carbon filter, eliminating gases produced during the process as well as any type of taste, which is why it is in a pleasant form for consumption.
- This process is carried out automatically, avoiding electricity and water consumption when the equipment is stopped.

Using reverse osmosis water treatment
Reverse osmosis salt water
Sea/salt water osmosis process
What does the salt water reverse osmosis process consist of?
The reverse osmosis process consists of applying pressure on a salt water solution and making it pass through a semipermeable membrane whose function is to allow the solvent (water) to pass through it, but not the solute (dissolved salts).
reverse osmosis to desalinate seawater
Water is an essential resource for life, and yet more than 40% of people have problems accessing it. Of the total on Earth, only 2% is sweet. It is found frozen in glaciers or in a liquid state in the ground. The latter is what people use every day. The rest, that is, almost all of it, is salty.
Subsequently, you will be able to answer the following questions: Can we take advantage of it to supply those places that need it most? Yes. Desalination technology makes it possible thanks to reverse osmosis engineering, equipment and services.
TRANSFORM SEAWATER INTO DRINKING WATER THROUGH reverse osmosis water treatment
Currently, reverse osmosis water treatment technology produces salt at the lowest energy cost per cubic meter of water.
If, on the other hand, you want to favor the flow in the opposite direction (from the most concentrated solution to the most dilute one), it is necessary to apply a hydraulic pressure (Force P) that must overcome the osmotic pressure and the natural flow of water through the membrane (figure c and d). Specifically, this is the phenomenon that takes place, for example, in a desalination plant where to get it salt-free water by applying a certain pressure on it and motivating its passage through semipermeable membrane

Reverse osmosis in wastewater treatment
Reverse osmosis wastewater treatment
Reverse osmosis in wastewater treatment
Approximately three-quarters of freshwater use in our country is for irrigation and industrial purposes (cooling, power generation, etc.).
For non-potable applications, treated wastewater is an excellent source of consistent, energy-saving water to facilitate the requirements needed in inconsistent sources.
Recycled effluent is also a productive solution to recharge groundwater sources (where the soil naturally filters water to a potable state, suitable for drinking), increasing the flow of rivers and streams, as water re-use gray in home and commercial applications.
Sterilizers for reverse osmosis wastewater treatment
Bacterial growth is always a concern in any type of water application. Not only is chlorine treatment expensive, but it can also be poisonous to plants at high enough concentrations.
Ultraviolet sterilizers can eliminate any bacterial or viral growth in water, without the use of dangerous or expensive chemicals.
Ultraviolet radiation instantly destroys microbiological organisms without damaging the water or leaving any type of harmful side effects.

Reverse osmosis in the food industry
Reverse osmosis process in the food industry
How the reverse osmosis water treatment process is carried out in the food industry
The process of reverse osmosis in the food industry It can be carried out using purifiers, which apply the immersed pressure to conduct the liquid through an impurity extractor membrane.
Certain components may arise that put aside reverse osmosis membrane for water treatment because of the pressure. In turn, certain concentrations are trapped by the water treatment system because they are dissolved impurities that cannot be eliminated with conventional filtration.
The end result is high-quality fresh water that gives food and drinks a better flavor. Some bottled water supply companies use the technique ofl reverse osmosis treatment for water to purify all kinds of liquids and package them for fine consumption.
What is reverse osmosis water treatment for in the food sector?
Uses of reverse osmosis in the food sector
One of the industries that most need purified water treatments is the food and beverage sector. For this reason, it is necessary to proceed to the reverse osmosis in the food sector to meet strict decontamination specifications and offer preventative solutions against disease.
In addition to providing greater security, the reverse osmosis water treatment technique makes food taste better. For example, the extraction of starch in potatoes has been used to produce many long-lasting foods that have a creamier texture when fried.
In turn, fruit concentrates gave way to powdered drinks, thus eliminating large quantities of water and allowing them to be used at any time. In addition to that, powdered juice takes up less space than the classic presentations of natural juice.
Other applications of the reverse osmosis in the food industry They are for the preparation of sugary juices, which require special treatment in order for them to last longer. And how can we forget whey, poles and even cookies that increasingly become more resistant to the passage of time and external environmental factors.
In conclusion, the application of food osmosis It serves to enhance the flavors, smells and colors of foods and drinks. That is why juices or vegetables are becoming more colorful and bright, thus becoming more attractive in the eyes of the consumer.
Reverse osmosis milk
What is reverse osmosis milk used for?
Reverse osmos in milk use
Frequently, Raw milk is subjected to reverse osmosis to concentrate the solids and separate the water from the rest of the nutrients.
Similarly, A nanofiltration process is applied when you want to eliminate salts and concentrate lactose and pasteurized whey proteins.
Reverse osmosis filtration is applied for: concentration of milk, whey or fermented UF
Reverse osmosis filtration processes for milk water treatment
In the dairy industry, four different membrane filtration processes are used: microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis. l
1st step water treated by reverse osmosis milk: Reverse osmosis
- Reverse osmosis is the process with the narrowest membrane possible in the separation of liquids. It concentrates the total solid material, and only water can pass through the membrane; All dissolved and suspended material is retained.
2nd reverse osmosis process for milk water treatment: Nanofiltration (NF)
- Nanofiltration separates a range of minerals from liquids, allowing only the fluid and certain monovalent ions to pass through the membrane.
3rd step water treated by reverse osmosis milk:: Ultrafiltration (UF)
- The ultrafiltration (UF) membrane separates the input material (e.g., skim milk) into two streams, allowing water, dissolved salts, lactose, and acids to pass through in either direction, while being retained. (and therefore, concentrate) proteins and fats.
4th reverse osmosis process for milk water treatment: Nanofiltration (NF): Microfiltration (MF)
- Microfiltration employs the most open type of membrane, which is used to separate bacteria, spores and fat globules from the flow; It is also used for the fractionation of skim milk.

reverse osmosis beer
Osmosis treatment attribute for beer water
Merit osmosis treatment for beer water: no impact on the water
Below we will briefly explain How can the state of the water in your beer impact and how to fix it.
Beer contains more than 90% waterIn addition to being essential for the production of the drink, it facilitates its process. For starters, water is used to steep the malt, which can affect the final result of the beer; On the other hand, it also helps to clean and rinse in several other processes, such as pasteurization, steam generation and CO2 management, for this reason, The composition and quality of the water are of vital importance.
Knowledge of the mineral composition and pretreatment of water is essential for brewing beer.
, since if it contains too many minerals that must be eliminated or reduced, it can unfavorably impact the flavor of our beer. Some common problems are usually the following:
- The ions present in the water supply will directly affect the flavor of a beer, for better and worse. The most basic discussion about water is about hardness. The longer the water is, the more ions it contains.
- The presence of calcium sulfate (CaSO4) or calcium carbonate (CaCO3) can give beer a slightly astringent or bitter taste.
- Football (Ca+2) and magnesium (Mg+2) in large quantities will produce metallic flavors.
- Sodium (Na+) in excess could give the beer a salty flavor.
- El chloride (Cl-), alone or combined with sodium, will give the beer a fuller-bodied flavor.
What additives should be added to reverse osmosis beer water?
Beer styles must be suitable for reverse osmosis water treatment use
Some beer styles are suitable for direct use of reverse osmosis water, such as Czech lager.
Almost all beers can be brewed with 100% RO water, but some beer styles require a few simple additions to get the best flavor.
Types of additives to add to reverse osmosis beer
These additives that must be added to reverse osmosis beer are called “brewing salts” and the most common are gypsum, calcium chloride, Epsom salts, chalk, sodium chloride, and baking soda. .
- Gypsum (CaSO4 or calcium sulfate) is used in water to bring calcium and sulfate. It is a white powder.
- Calcium chloride (Pickle crisp or CaCl2) is used to add calcium and chloride. It is a highly hygroscopic white powder; That is, it easily absorbs moisture from the air, so it should be stored in small quantities in tightly closed containers.
- Epsom salt (MgSO4 or magnesium sulfate) is used to provide magnesium and sulfate.
- Table salt (NaCl or sodium chloride) adds sodium and chloride to water. Non-iodized salt is available in grocery stores for this purpose.
- Chalk (CaCO03 or calcium carbonate) has traditionally been used in the past as a way to raise the pH of the mash where necessary. However, it does not dissolve well without extraneous measures and should be avoided by most brewers.
- Sodium bicarbonate (NaHCO3) can be used in those exceptional cases where the pH of the mash must be raised.

Osmosis water for irrigation
Reverse osmosis: water treatment for agricultural irrigation
Osmosis irrigation
One of the treatments used to adapt water for agricultural work is reverse osmosis for water treatment, the main technology in water treatment plants for agricultural use.
What does the reverse osmosis water process for irrigation consist of?
Succession of reverse osmosis water treatment for irrigation
- The process of water treatment by reverse osmosis for irrigation consists of applying pressure on the water to make it pass through a semipermeable membrane, which allows the passage of pure water, but not the solute or dissolved salts.
- This is how pure water passes through the membrane, from the side where the concentration of salts is higher, to the side where the concentration is lower.
- As a result, we obtain that the concentration of salts is minimized in favor of pure water, which increases considerably.
Advantages of osmosis water for irrigation
Among others, we find that reverse osmosis treatment for water For irrigation and agriculture it has the following advantages:
- Eliminates harmful components for agricultural irrigation.
- Reduces hardness, nitrates, sulfates, chlorides, sodium and heavy metals.
- It can supply any volume of water demand.
- Compliance with water quality requirements.
- Savings in water use.
- Environmental preservation.
- Savings in energy and fertilizer costs.
Osmosis water for aquariums
Why is osmosis water used for aquariums?
Reasons for using osmosis water for aquariums
Osmosis water is increasingly used by aquarium hobbyists who take care of both Marine fish and sweet water, since the water produced by these systems is of high quality, since removes more than 90% of impurities.
It must be taken into account that reverse osmosis systems are also used to obtain highest quality mouth water for human consumption. Likewise, it is recommended for our pets and for certain plants such as bonsais, orchids or geraniums.
Reverse osmosis is a complete water purification system that removes all types of contaminants from tap water and contributes to the work of the aquarium filtration system.
How do reverse osmosis filters for aquariums work?
Operation of reverse osmosis filters for aquariums
To convert the network water into osmosis, the system incorporates several treatment stages, each of them with a specific function. These are the stages that are generally needed to obtain osmosis water for the aquarium:
- Sediment prefiltration
- Cartridge with activated carbon
- Membrane
- Filter
- Deionization cartridge
Benefits of osmosis water for aquariums
1. Benefits of osmosis water for aquariums: Pure water
- The result is pure water, free of algae, nitrates, heavy metals, minerals and salts. So what advantage does it have? It leaves us free to precisely add the substances required for the health of the fish, such as salts, minerals and other types of additives.
2. Advantage Aquarium water treatment by reverse osmosis; Savings in materials
- Water treated with an aquarium reverse osmosis water treatment is permitted. save in expenses of certain maintenance elements of the aquarium, such as resins or some chemicals treatment.
In saltwater aquariums, the addition of nitrate or heavy metals is not required. Furthermore, you can stimulate the growth of algae and plants in both freshwater and marine tanks.
3. PRO reverse osmosis for aquarium water treatment: Specific systems
- It must be taken into account that, except for small fish tanks, reverse osmosis water treatment systems for aquarium water treatment are specially designed for that use.
- These teams will be different depending on the capacity of the aquarium, since each one produces different volumes of water per day.
4. Advantage in reverse osmosis treatment for aquarium water: Alternative to tap water
- In Spain, the quality of water varies depending on the municipality supply. In this sense, cities such as Burgos or San Sebastián enjoy high water quality, while others such as Vigo, Madrid, Guadalajara, Palencia, Orense or Málaga are at the bottom.
- In addition, we must take into account the hardness of our tap water, since most fish are affected if it contains a lot of lime.

Types of reverse osmosis equipment
Types of osmosis: standard, compact or with pump
1. Standard reverse osmosis equipment
To begin with, we have a water reverse osmosis device with 5 stages, which is divided into two bodies that have a set of filters and the pressurized tank.
Standard reverse osmosis: This is the most widespread option on the market.
- To begin with, standard reverse psmosis is the one that offers the best value for money. Thus, most of the osmosis on the market and the most economical ones are standard, that is, they are not direct.
- In this option specifically, we must pay special attention to the quality of the membrane, since it is responsible for the quality of the water that is generated.
Details Basic 5-stage water osmosis system
- These osmosis, like all, They have two carbon filters, a sediment filter and a membrane.
- In addition, they have a pressurized tank where water accumulates, since osmosis generates it very little by little.
- Likewise, they are hydraulic osmosis, that is, they work with the energy of water and do not have an electrical system, which prevents them from having extras that require electricity, such as autoflushing.
- That means we have a decent flow of water but if we take out too much at once we will leave the tank empty and we will have to wait to take out more.
Standard reverse omosis 6 stages
- The additional stage is the one corresponding to an ultraviolet lamp, through which an attempt is made to ensure the elimination of all the bacteria present in the water.
Cons standard reverse osmosis
- The disadvantage of these osmosis systems is that they have unsealed filters, that is, they are changed by hand by removing the old filter and inserting a new one into the container. As they are unsealed filters, the possibility of contamination when changing them is greater than with sealed filter systems.

2. Compact water osmosis system
Secondly, there is a compact osmosis system that is housed in a housing where the components and filters are placed, saving space.
Advantages of compact reverse osmosis equipment
- This is undoubtedly the ideal option for places where there is little space.
- Generally, the compact ones are usually osmosis that come sealed inside a box, so as they have a protective casing they are not damaged by impacts.
- Their advantage is that they are more beautiful and usually have security systems. sealed filters, which, as we have said, offer more security when carrying out maintenance.
- On the other hand, they are usually electric, which means that they may have extras such as water and pressure sensors and solenoid valves that regulate their operation.
- In this way, with these extras the performance of the purifier is improved.
- Other systems, such as Aquastop, detect leaks and paralyze the system to avoid accidents caused by leaks.
Disadvantages of compact reverse osmosis
- However, the maintenance of compact reverse osmosis should in any case be done by a professional.
- Likewise, compact reverse osmosis equipment is somewhat more expensive than standard equipment, although the quality of the water ultimately depends on the quality of the membrane.

- They have different purification stages and are effective in reducing sediments, heavy metals, contaminants and water salts.
- If there are people in the home with cancer, hypertension, liver or gastrointestinal problems, they can benefit from this system that eliminates the presence of sodium.
- One of the benefits of having the system Inverse osmosis at home is that a minimum consumption of electrical energy is required, so you should not worry about a high increase in the monthly bill. Furthermore, unlike other systems, its maintenance is low thanks to its molecular design.
Possibilities in reverse osmosis pool devices
- With sediments: They are a pretreatment that eliminates suspended particles.
- With carbon prefilters: Protects the membrane from possible oxidation due to chlorine.
- Osmosis membrane: Made of semi-permeable polyamide that retains salts dissolved in water and suspended particles.
- With drain flow regulator: Controls the drain flow and creates the necessary counterpressure.
- Accumulation: With a pressurized tank it guarantees instant water flow.
- Carbon post-filter: final treatment after the membrane that eliminates generated flavors.
How many stages should my reverse osmosis equipment have?
Most water filtration experts agree that 5 stages is the standard to purify most water for human consumption, although 6 and 7 stage equipment is also sold, the filter types may vary from one to another. Of course, there are also 3 and 4 stage ones, although they are less common.
Before purchasing any reverse osmosis equipment, You should make sure what filters are included and what their function is..
List of all types of filters in a reverse osmosis equipment
1# Sediment prefilter
Its opening is 5 microns and can effectively filter rust, sand and solid impurities in the water.
2# Granular activated carbon (GAC) pre-filter
It can effectively absorb water chlorine, by-products, odors, colors and other materials.
3# Block activated carbon prefilter
Its aperture is 1 micron. It can remove smaller particles, suspended solids and colloids.
4# Semipermeable membrane
Its aperture is 0,0001 microns. It can effectively remove many bacteria, heavy metals, pesticide residues and other harmful substances.
5# Activated carbon post-filter
Regulates the taste of the water and eliminates any possible residual taste and odors coming from the tank.
6# Remineralizing postfilter
It adds minerals to water and increases its alkalinity, eliminating any sour taste sensation and improving its taste.
7# UV Postfilter
It is usually used as a last step to eliminate and inhibit the growth of microorganisms. The UV system can reduce 99% of bacteria and viruses in water.

Tips for buying a reverse osmosis system
How to choose an osmosis water system
Choose the system carefully since not all reverse osmosis equipment is the same.
It is advisable to choose that osmosis water equipment which provides us with lower water consumption on the market. The advantages of best osmosis equipment market is that they are small in size and do not require connection to the electrical grid.
When choosing a reverse osmosis equipment supplier, we have to opt only for those that offer us the maximum guarantee of security and have the most modern technology. We must also assess that this device can be configurable according to the needs we have, and that it meets the maximum guarantees in terms of security.
A system with these characteristics provides many health benefits, transforms tap water into quality water, in addition to saving us a lot of money and time throughout the year.
To buy a reverse osmosis system it is advisable to research and have knowledge about the product, you have to know how your water filters work or which is the best system that best adapts to the conditions of your home.
If you are a large family, water consumption will be greater, so you will need a certain product than a couple.
Not all systems are the sameCurrently on the market there are many products for water purification but not all offer the same results, it will depend on the material with which they are made, the type or how many purification stages they take.
Tips for buying reverse osmosis equipment
What to take into account when choosing reverse osmosis equipment?
If you want your house to have a quality system, that lasts a long time and remains intact like the first day, plus it fits your needs and your budget It is highly recommended to follow the following guidelines:
- Kind of team. Among the domestic reverse osmosis models, two types of device stand out:
- Standard: Standard equipment is the most basic and, therefore, usually the cheapest. They are usually placed under the sink, inside the cabinet, so they are not very discreet.
- Compact: For small apartments or for homes where more discretion is sought than with the standard, the compact reverse osmosis system is the best solution. Models like the Binature have opted for rounded shapes and a careful design to better adapt to kitchen spaces, being the most compact equipment on the market.
- Reverse osmosis equipment has between 3, 4 or 5 purification stages.
- However ideally it should have 5 stages. Because? If the water comes from a well or an area with high levels of sediment, this type of product will act correctly, filtering without any problems. Otherwise, if there were fewer stages, the performance would not be the same.
- Materials are one of the points on which special emphasis should be placed.. A product that does not have quality materials will break down more easily, it will not have the same effect as those reverse osmosis systems with good materials. One point to pay attention to is to check if the product is supported by certifications such as European Conformity (CE).) or Water Quality associations. This will tell us that it is a reliable and high quality product, a safe investment.
- Price. When choosing domestic reverse osmosis equipment we have to take into account that the need for a home's water supply is generally not very great. Therefore, we must try to buy equipment that meets our needs, something that is measured by liters per minute. For example, in domestic reverse osmosis 1,5 liters of water per minute is a reasonable figure, since that amount can be obtained 24 hours a day.
- What is the amount of water you want your reverse osmosis product to filter? Generally this depends on the size of the home and the number of people who live in it. You should buy the product that best suits your needs.Production of liters per minute What are your home's purified water needs? Normally, 1,5 liters of osmosis water per minute is usually more than enough for a home, but for example, if an almost continuous flow is necessary, it is worth thinking about other more powerful models.
- tank capacity It has to be large, it is advisable that it be greater than 5 liters. The filter tubes must match the capacity of the tank, since they will be connected to it and to the tap.
- Maintenance cost. We will have to take into account that it will be necessary to change filters at least once a year. Therefore, low maintenance cost equipment like the Sintra is an interesting option in the short and long term.
- Production-rejection value. Reverse osmosis usually includes a process in which water is divided into two parts when passing through a membrane: a potable part and a rejection part, which is not suitable for consumption. In this sense, we can choose an ecological product, such as the Advance model.
- Direct flow or with tank Some of the most modern systems have direct flow, without the need to include a stagnant water tank. This feature improves the quality of the process, but also has an impact on the price.
- With or without pump. We can study the option of including a water pump or not. The water pump is recommended if you live in a building with low pressure, but if the pressure is adequate, it is not necessary.
- Be easy to install.

Situations to use a reverse osmosis pump
Reverse osmosis with pump: When the pressure is variable.
In many locations with low supply pressure or when supplied from tanks or wells, maximum pressures that exceed the previously recommended figure are usually reached.
In these cases, the pump stops and starts again when the pressure drops.
Therefore, it is important to observe the measurements on the pressure gauge while consuming water and if it reads less than 3,5kg/cm2, you will need to purchase a pump.

Suggestions for buying industrial reverse osmosis water purifier
INDUSTRIAL REVERSE OSMOSIS EQUIPMENT
How does industrial reverse osmosis (RO) work?
While, with normal osmosis, osmotic pressure dilutes the salt content by filtering the non-salinized water source into the saline water source, reverse osmosis (RO) uses this same concept to drive the highest concentration of water through the semipermeable membrane - separating approximately 95 to 99 percent of all Total Dissolved Solids (TDS) from the treated water and decreasing salinity in the process.
The more the water is filtered, the greater amounts of pressure are required to continue pushing the feed water forward: the Reverse Osmosis (RO) System has to account for the increase in osmotic pressure throughout the Reverse Osmosis process ( RO) since the feed water grows continually salinized. These Industrial Reverse Osmosis (RO) systems are designed to treat tap, brackish and sea water to produce clean drinking water for human consumption and for use in many water treatment applications and industries worldwide.
Types of industrial RO systems
Industrial Brackish Water Reverse Osmosis Systems
Brackish water is a source of salt water that has a lower salinity than ocean water and a higher salinity than fresh water sources, this can happen for many different reasons, but most commonly in nature this occurs in the estuaries.
Many single-stage, single-pass reverse osmosis (RO) systems also create brackish reject water.
Two-stage, two-pass reverse osmosis (RO) systems can reuse this brackish reject water as long as the TDS level is within the range of the membranes.
This makes industrial brackish Reverse Osmosis (BWRO) Systems ideal for treating water with a medium level of salinity, coming from the tap or other brackish sources.
Industrial reverse osmosis and seawater desalination systems
Industrial seawater reverse osmosis systems are designed to treat large sources of water with high levels of salinity, whether from the ocean or other water sources with large amounts of contaminants.
Depending on the level of total dissolved solids (TDS), some reverse osmosis (RO) systems can also treat the reject water produced by the industrial seawater reverse osmosis (SWRO) system.
This is a more difficult task to accomplish for seawater RO systems than brackish RO systems, as the reject water from the seawater RO system has a much higher level of TDS that can be easily out of reach of the reverse osmosis (RO) membrane.
Another key feature that differentiates industrial seawater reverse osmosis (SWRO) systems from industrial brackish water reverse osmosis systems is that seawater reverse osmosis (RO) systems require more power to produce higher pressure to overcome the higher osmotic pressure in high salinity waters, which may slightly affect the maintenance cost of these systems
Efficient industrial RO systems
Industrial reverse osmosis (RO) systems with energy recovery devices (ERD) installed will use less energy as the device is designed to capture and reuse energy from high-pressure motorized pumps.
This process can save energy for high-pressure pumps by decreasing the amount of horsepower (HP) needed to keep them running, and the industrial reverse osmosis (RO) system as a whole.
How to make reverse osmosis at home
What do we need for a homemade reverse osmosis equipment?
The first thing will be to get all the elements that make up the filter bed:
- A tank: to introduce the filter bed
- Pebbles of different sizes from pebble-type to medium-sized
- Fine sand (beach type)
- Activated carbon
We must bear in mind that both the tank and all the elements must be washed previously with plenty of water using anti-bacterial detergents.
How to assemble a homemade reverse osmosis system filter?
The layout is very simple, you must place:
- First the sand
- Second some pebble type stones
- Then the activated carbon bed
- Finally, the medium-sized stones and the largest ones at the bottom.
In this way, the dirty water enters through the top and will filter downwards, passing through all the layers, obtaining more crystalline water at the bottom of the tank. Of course there are more sophisticated versions that carry this filtered water through a pipe that leads to a tap where we can fill jugs, glasses...
If you want it easier, you already know that we are dedicated to the marketing of filters of all prices, although as weekend entertainment so that children can learn how to make a homemade water filter, it is not bad at all.

Why is a storage tank necessary in a reverse osmosis system?
Why use a storage tank in a reverse osmiosis system
Use of reverse osmosis water storage pressure tank
A reverse osmosis system is slow: It takes one minute to purify 6 to 9 centiliters of water. If you were to turn on the tap to pour a glass of water and fill it at production speed, you would have to wait at least 5 minutes for it to fill. With a storage tank this inconvenience is avoided.
How the tank of a reverse osmosis equipment works
Operation of the tank of a reverse osmosis equipment
Reverse osmosis tanks are generally pressurized, that means that inside they have an air chamber at a pressure of 0,5 bar and another water chamber. When the water reaches the tank, the air chamber begins to compress, thus providing the water with the necessary pressure and force to come out of the tap.
As a general rule, pressurized tanks have a useful capacity much smaller than the total volume of the tank.
Over time, the tank's air chamber may lose some pressure, so it is advisable to do an annual check, coinciding with changing the filters.

Symptoms of hard water
- Clothes that look dirty and feel rough and scratchy
- Dishes and glasses stained with mineral buildup
- Film on glass shower screens, shower walls, bathtubs, sinks, faucets, etc.
- Sticky and lifeless hair
- Dry, itchy skin and scalp
Hard water does not cause any adverse health effects, so why soften water? Just because drinking hard water isn't bad for you doesn't mean it isn't costly in other ways.
Hard water costs
- Inefficient or failed appliances
- clogged pipes
- Higher electricity bill because scale buildup makes it harder to heat water
- Additional costs for detergent, shampoo and cleaning products
Water softener properties
The solution against lime:
Prevent and control, through the ScaleBuster water softener, the lime formation without using chemicals, effectively and ecologically altering the crystalline structure to eliminate its capacity for encrustation and adhesion, maintaining, at the same time, all the mineral properties of the water that are essential for our health.
What is the descaler for?
Depending on the area you live in, the water coming into your home may exceed the recommended lime levels.
Water with a high level of lime is called hard water and has a high concentration of minerals, particularly calcium and magnesium salts.
Consumption of water that is too hard can cause both health problems (dryness and eczema in atopic skin), and breakdowns in household appliances in contact with water (washing machine, dishwasher, coffee maker, boiler, electric heater or water heater).
Lime problems in water
The main problem that consumers face, in terms of comfort, when using household water is limescale.
- Scale and limescale residue in sanitary installations (toilets, sinks, drains, taps and shower heads).
- Lower pressure in the water in the home. Formation of lime deposits in pipes that reduce the internal diameter as well as the water flow.
- Disadvantages in hygiene: dryness and itching of the skin and scalp, as well as dermatological problems.
- Embedding in domestic hot water generation equipment (boilers, water heaters and water heaters), household appliances (washing machine, dishwasher) and in all our pipes.
Benefits of using a descaler
The advantages of using a descaler are many:
- Extends the life of appliances by preventing lime buildup from causing breakdowns or damage.
- Get you to save on anti-lime products and on pipe and appliance repairs.
- Prevents skin problems and dryness for the whole family.
- Extends the life of appliances by preventing lime buildup from causing breakdowns or damage.
- Get you to save on anti-lime products and on pipe and appliance repairs.
- Prevents skin problems and dryness for the whole family.
- Very economical descalers and without the need for continuous and expensive maintenance on bags of salt or chemicals to keep the system running.
- Without wasting liters of water as occurs in ion exchange softeners. It is important to save, in addition to conserving and not wasting this precious resource.
- Without the need for an electrical connection, ScaleBuster generates its own energy (autonomous technology).
- It does not need drainage, nor does it generate wastewater (sodium), so it does not discharge or contaminate groundwater.
- Drinking, salt-free water suitable for human, animal and plant consumption. Salt-free water softeners are also the ideal complement for those on a low sodium diet.
- Less aggressive water without causing itching and irritation to your skin or hair.
- Very compact equipment, save space and are easy to install in all types of pipes.
Is it worth using a water softener?
How could a water softener benefit you?
Household cleaning products: Hard water affects the strength of cleaning products. Conditioned water offers greater cleaning power by reducing the amount of soap needed by up to 70%.
Washing and care of clothes: Your clothes will be softer, cleaner and whiter, and the colors will be much brighter. Using soft water increases the life of clothes, towels and bedding by up to 33% and extends the life of your washing machine.
Dishwashing and glassware: Dinnerware and glassware will be easier to clean and stain-free. Soft water is better for your skin, so your hands will feel softer and look better. Softened water also extends the life of your dishwasher.
Water heaters: According to a recent study by the Battelle Institute, hard water can cause up to 24% loss of efficiency in water heaters. With softened water, heaters maintain original factory efficiency over a 15-year lifespan. The same goes for dishwashers or any other hot water appliance.
Bathing and showering: In the bathroom, your soap and shampoo will lather better, with less effort. Your hair and skin will feel noticeably cleaner and softer. Sinks, showers, bathtubs and toilets will have less soap residue and dirt.
Preventing scale in plumbing and pipes: Over a period of time, scale forms and clogs the pipes. When pipes become clogged, water flow is restricted and water pressure is drastically reduced. Water softening eliminates these problems significantly and eliminates scale previously formed over time.
Stains reduced: Water softeners prevent rings, stains or unsightly mineral buildup in bathtubs, showers and sinks. Soft water also preserves the beauty of faucets and countertops.
Main differences and advantages between softener and osmosis
Comparison between softener and osmosis
It is logical that you may have doubts when deciding which of the two solutions is most appropriate for your home. In this post we explain the main differences and advantages of both systems.
How a water softener system works
The most common and effective way to eliminate the effects of hard water is to remove the minerals that cause hardness. Water softeners remove calcium and magnesium by ion exchange . The mineral ions that cause hardness are captured by the softener resin and are exchanged for sodium or potassium ions. Soft water does not contain minerals that cause scale.
Water softening by ion exchange
- The tank of a water softener is filled with resin beads coated with sodium ions. As hard water passes through, the resin beads act as a magnet, attracting calcium and magnesium, or hardness, ions in exchange for sodium ions.
- Eventually, the resin beads become saturated with mineral ions and must be "recharged." This process is called regeneration .
- During regeneration, a strong brine solution passes through the resin tank, bathing the resin beads in a stream of sodium ions. These sodium ions replace the built-up calcium and magnesium ions that are sent down the drain.
- Regeneration goes through some cycles including backwash y brine extraction . The process is electronically controlled by the control valve at the top of the resin tank.
- Once the regeneration process is complete, the resin bed is quickly rinsed to remove excess sodium.
- The softener is ready to remove hardness as the water enters the home.

Reverse osmosis rejection water
Reverse osmosis water rejection
Reject water in reverse osmosis in wastewater treatment
The rejection of water from reverse osmosis systems (it is a challenge for those growers who use this equipment to obtain the best quality of water for irrigation) can be presented as a drawback when deciding to use an osmosis system.
When we need large quantities of osmosis water we must know that the amount of water discarded will be at least double the water produced by the osmosis equipment.
That is why we wanted to publish an article talking about the rejection water from reverse osmosis systems, the different factors to minimize it and how to take advantage of this water.
What is reject water in reverse osmosis systems?
In all reverse osmosis systems, the reject water or residual water is the water that comes out of the tube that is connected and sent to the drain (the black one).
Once the tap water has passed through the sediment and carbon filters, it enters the reverse osmosis membrane, which will purify a quantity of water and send another quantity of water with the dissolved salts that we want to eliminate to the drain.
Thus, the rejection water is clean water without chlorine but with an EC which will be between 15-20% higher than that of tap water.
Circumstances to evaluate to minimize the water rejected by a reverse osmosis system
1st factor to Minimize the water rejected by a reverse osmosis system: The EC of the grid water
- Reverse osmosis equipment They remove up to 95% of salts from water. That is, depending on the EC of the tap water, so will the quality of the purified water.
- The life of the membrane will depend directly on the EC of the tap water. The higher the EC, the life of the membrane will decrease due to the amount of salts retained. Although the positive part of this is that we will reject the minimum amount of water possible.
2nd parameter to review to minimize the water rejected by a reverse osmosis system: The water inlet pressure
The manufacturers of reverse osmosis membranes recommend a minimum pressure of 4,3 Kg/cm2 (BAR) so that the membrane works in good conditions. Therefore, water production will increase or decrease depending on the pressure of water entering the membrane. Insufficient water pressure will cause the equipment to produce less water and, at the same time, water rejection will be greater. If we have a water pressure lower than the recommended one, we must install a Pressure Pump Kit. In this way we will ensure that the equipment works in optimal conditions.
3rd element: Minimize water rejected by a reverse osmosis system by installing a flow restrictor
- The amount of water rejected by a reverse osmosis system will depend directly on the flow restrictor installed.
- Many osmosis equipment is designed to remove 4:1, 5:1, 6:1 or more.
- This means that for every liter of water produced, 4, 5 or 6 times more water is needed to be eliminated through the drain (or garden).
- GrowMax Water reverse osmosis systems are designed to reject ONLY two liters of water for every liter of water purified, this saves a lot of water!

Reverse osmosis waste water recycling and reuse systems
How can we take advantage of the reject water from reverse osmosis?
Water recycling and reuse systems thanks to reverse osmosis water treatment
Maintaining the decline in the number of freshwater sources we have is vital to the preservation of our planet, and to ensure the safety of our natural freshwater sources.
We have designed hundreds of ultrafiltration systems that purify water around the world, and we design more every day.
If you have wastewater treatment needs, there are systems in place to find out how we can meet any purification or recycling standards you may have.
How to Reuse Reverse Osmosis Reject Water
As we have mentioned previously, reject water contains a greater amount of salts than tap water. We have also commented that it is clean water of sediments and without chlorine, which will allow us to use it for other uses. For example, by accumulating the reject water in a tank, we can use it to clean growing rooms and cabinets, trays, pots, tools, etc.
In addition, we can also use it to mop floors or for water in sinks. Also for watering lawns, fruit trees or plants and flowers that do not need salt-free water. Finally, for all of you who have a pool, do not hesitate to fill it with the reject water generated by reverse osmosis equipment.

How to start osmosis?
How to purge reverse osmosis
Below we explain how to start up a reverse osmosis unit, with all the details so that you can do it yourself:
- Turn off the inlet water: To carry out the installation, make sure that the inlet water to the osmosis equipment is closed.
- Clean the prefilters: Cleaning the prefilters prevents the dirt they come with from the factory from entering the membrane, potentially clogging it completely. To clean, disconnect the tube that carries the water to the membrane and direct it towards a container. Next, turn on the water and let it run until it is clear. Finally, the tube must be connected back to the membrane and the osmosis caps are closed.
- Fill and clean the tank: Open the water inlet valve and let the tank fill for approximately one hour. After this time, empty it completely by opening the service tap (the one installed in the sink). This process of filling and emptying the tank must be repeated once more and the compact osmosis will be ready for use.
Don't forget that... Once started, it is advisable to carry out regular maintenance on the compact osmosis equipment to ensure its optimal functioning. To do this, it is necessary to change the prefilters, the membrane and the postfilter with certain frequency.
