txo alkalinity

---

Nws tsis yog ib txwm yuav tsum tau txo cov alkalinity. Vim tias cov khoom siv dej feem ntau muaj qis qis, thiab vim tias feem ntau pH regulator ib txwm yuav tsum tau txo cov pH (thiab thaum noj cov kua qaub kuj tseem txo cov alkalinity).

Tab sis muaj cov xwm txheej, xws li hauv qee cov dej hauv av, qhov chaw muab khoom los nrog siab pH thiab alkalinity. Los yog nws kuj tshwm sim hais tias cov tshuaj tau ntxiv indiscriminately rau hauv dej, ua kom muaj zog imbalances, ib tug ntawm lawv yog siab alkalinity.

Txhawm rau txo alkalinity txoj kev sib txawv yog tias pH siab lossis qis:

Txo alkalinity nrog siab pH

Tsis txhob sim txo qis pH vim nws yuav nyuaj heev. Lub siab alkalinity muaj lub zog siab rau neutralize acids (nws yog lub ntsiab lus ntawm alkalinity), thiab cov kua qaub uas peb txhaj yuav muaj tsawg heev ntawm pH.

Thiab nyob rau hauv cov ntaub ntawv no, cov txheej txheem muaj kev txhaj tshuaj etching (tseem hu ua hydrochloric acid los yog salfumán los yog muriatic acid) kom deb li deb tau nyob rau hauv qab ntawm lub pas dej ua ke (nrog rau lub raj, piv txwv li). Peb yuav tsum siv cov tshuaj hydrochloric acid kom ntau li ntau tau, vam tias 30%.
Thaum peb txhaj cov kua qaub, peb yuav tsum tua cov dej phwj tuaj kho, thiab nws tsis tig mus txog rau hnub tom qab.

Tus nqi ntawm hydrochloric acid hauv cc thiab ntawm 30% uas peb xav tau yog:
1,55 x (m3 ntawm pas dej ua ke) x (tam sim no nyeem alkalinity – xav alkalinity theem)

Nrog peb piv txwv ntawm 50 m3 pas dej ua ke, thiab xav tias peb pib los ntawm alkalinity ntawm 180 ppm, kom ncav cuag alkalinity ntawm 100 ppm peb xav tau:
1,55 x 50 x (180 - 100) = 6200 cc = 6,2 litres ntawm 30% etching

Peb yuav tsum tsis txhob sim qis dua 40-50 ppm ntawm alkalinity txhua hnub. Yog tias tsim nyog, muab faib ua ob peb ntu.

Thaum 24 teev peb ntsuas qib alkalinity thiab pH, thiab peb tuaj yeem pom 3 qhov xwm txheej:

• Alkalinity ntawm 80 thiab 120, thiab pH nyob rau hauv ntau yam zoo li (kwv yees tsawg dua 7,5 rau pas dej ua ke nrog chlorine, thiab 7,8 rau pas dej nrog bromine): nyob rau hauv cov ntaub ntawv no peb ok, peb ua tiav, nws yog ib qho yooj yim.
• Alkalinity tseem siab dua 120, thiab pH ntau dua lossis sib npaug rau 7,2. Peb tuaj yeem rov ua cov txheej txheem ntawm kev txhaj tshuaj etching, tab sis teeb tsa peb tus kheej lub hom phiaj ntawm kev txo qis alkalinity ntawm 10 mus rau 10 ppm. Qhov no yog vim hais tias pH yuav luag ntawm qhov txwv, thiab yog tias peb mus deb dhau nws yuav poob mus rau theem uas peb yuav tsis tuaj yeem tsa nws tom qab.
  Qhov tseeb, yog tias nyob rau hauv ib qho ntawm cov kev sib tham pH poob qis dua 7,0 peb yuav tsum tsis txhob txuas ntxiv, thiab peb yuav tsum siv txoj kev piav qhia hauv qab no kom txo qis alkalinity nrog pH tsawg.
• Alkalinity tseem siab, tab sis pH qis dua 7,0 - 7,2: peb yuav tsum tsis txhob txuas ntxiv, peb yuav tsum siv cov txheej txheem txo alkalinity nrog pH tsawg.

Txo alkalinity nrog pH tsawg

Thaum pH qis thiab alkalinity siab, nws yog qhov xwm txheej phem tshaj plaws, vim nws yog qhov nyuaj tshaj plaws kom rov qab tau qhov sib npaug. Yog tias peb siv cov kua qaub, pH yuav poob ntau dua, thiab tom qab ntawd peb yuav tsum tau muab cov hauv paus kom sib npaug, tab sis lawv yuav ua rau cov alkalinity nce ntxiv, thiab peb nkag mus rau lub voj voog. Nco ntsoov tias pH thiab alkalinity yog yuav luag ib txwm hloov nyob rau hauv tib txoj kev coj, thiab yog li ntawd lawv tsav tsheb nyob rau hauv lub opposite kev taw qhia yog tsis pom tseeb.

Raws li peb tsis tuaj yeem nce pH nrog pH nce ntxiv (vim tias alkalinity yuav nce ntxiv), ces peb yuav tsum siv txoj kev hu ua aeration, uas cov dej raug rau lub cev "txhaj tshuaj" cua kom nws poob nws cov pa yaj, tshwj xeeb carbon dioxide (CO₂ ). Tsis tau mus rau hauv ntau cov tshuaj ntsuam xyuas, hais tias los ntawm dissolving CO₂ nyob rau hauv dej nws pH txo, thiab yog hais tias peb tswj kom rho tawm ntawm dej, peb yuav nce nws.

Koj tau nyeem kom raug, los ntawm aerating dej zoo peb tswj kom tshem tawm CO₂ thiab tsa nws cov pH, tsis muaj tshuaj ntxiv, yog txheej txheem lub cev.

Muaj ntau txoj hauv kev los ua kom cov dej ntws tawm, txhua yam koj xav tau. Koj tuaj yeem taw qhia cov thrusters los tsim me ntsis vortex, tab sis cov nyhuv me me. Koj tuaj yeem txaws txhua hmo…. Tab sis qhov tseem ceeb tshaj plaws yog tias koj ua ib qho me me "kwj dej": nrog PVC yeeb nkab thiab ob peb lub luj tshib koj ua ib hom giraffe; Koj txuas ib kawg mus rau lub impeller, thiab nyob rau lwm yam koj muab ib tug PVC plug nyob rau hauv uas koj ua ib tug me me qhov, zoo li nws yog lub taub hau da dej. Lub luj tshib qis tuaj yeem yog 45 degrees kom lawv "plug" dej ncaj qha rau hauv pas dej.

Koj qhib qhov pom, thiab yog tias koj tuaj yeem npog lwm lub impellers kom lub siab siab dua, qhov zoo dua. Cov sijhawm ua haujlwm yog xav tau, nws nyob ntawm qhov loj ntawm lub pas dej thiab pH theem, tab sis koj yuav tsum tau khiav nws tsis pub tsawg tshaj 6-8 teev. Thiab koj yuav pom tias pH yuav tau nce me ntsis.

Lub luj tshib thiab cov yeeb nkab yog ib qho yooj yim kom tau, tej zaum yuav nyuaj dua yuav ua li cas txuas rau lub impeller. Yog tias koj lub pas dej impellers yog cov ABS dawb uas muaj lub hau ntswj, koj tuaj yeem koom nrog 32mm PVC yeeb nkab nrog cov hauv qab no:

Thaum peb tswj kom nce pH mus rau 7,2, peb rov txhaj tshuaj hydrochloric acid kom txo cov alkalinity. Qhov siab dua peb tau tsa cov pH, qhov zoo dua, vim peb tuaj yeem kho qhov ntau ntawm alkalinity. Yog tias peb tuaj yeem nce mus rau 7,6, txhua yam zoo dua. Nco ntsoov tias koj tsis tas yuav kho alkalinity uas yuav txo qis pH hauv qab 7,0 - 7,2.

TSEEM CEEB: Yog, yog, raws li koj nyuam qhuav pom, dej tsaws tsag, dej tsaws tsag, thiab lwm yam. hauv cov pas dej lawv tsis yog "tsis muaj txim“…. muaj qhov cuam tshuam ncaj qha rau kev nce pH, yog li nws siv (los yog tsim txom) tej zaum yuav contraindicated nyob ntawm tej yam kev mob ...

Dawb residual chlorine, tag nrho cov tshuaj chlorine

Chlorine yog cov tshuaj tua kab mob ntau tshaj plaws hauv pas dej da dej thiab spa, thiab nws lub hom phiaj tseem ceeb yog los tua kab mob thiab oxidize cov kab mob hauv dej, yog li muab kev tiv thaiv rau cov neeg ua luam dej. Cov tshuaj chlorine uas muaj cov pas dej ua ke thiab muaj peev xwm oxidizing cov kab mob hauv dej yog hu ua dawb residual chlorine. Cov tshuaj chlorine uas tau tas nws lub zog tua kab mob los ntawm kev ua pa nrog cov kab mob hu ua chlorine ua ke. Tag nrho cov tshuaj chlorine yog qhov sib npaug ntawm cov tshuaj chlorine uas tsis muaj chlorine thiab khi chlorine. Cov chlorine dawb residual nyob rau hauv lub pas dej ua ke yuav tsum nyob nruab nrab ntawm 0,3 thiab 1 mg / L, thiab qhov pom zoo cov tshuaj dawb residual chlorine nyob rau hauv lub thermal dej yuav tsum nyob nruab nrab ntawm 3 thiab 5 mg / L.

cyanuric acid

Cyanuric acid, tseem hu ua "stabilizer" lossis "conditioner," ua rau cov tshuaj chlorine ruaj khov thaum raug tshav ntuj ultraviolet rays. Ob chlorine tebchaw (dioxy thiab trioxy) twb muaj qee cov cyanuric acid. Kev siv cov tshuaj tua kab mob txuas ntxiv tuaj yeem nce qib ntawm cyanuric acid. Cov ntsiab lus cyanuric acid yuav tsum tsawg dua lossis sib npaug li 50 mg / L.

CEEB TOOM:

Txhawm rau kom tau txais cov txiaj ntsig ntawm cyanuric acid, pH yuav tsum nyob nruab nrab ntawm 7.0-8.4 thiab tag nrho alkalinity yuav tsum tsawg dua lossis sib npaug li 240 mg / L.

tag nrho alkali

Tag nrho alkalinity yog ib qho kev ntsuas ntawm cov khoom alkaline (tsuas yog bicarbonates thiab carbonates) hauv dej. Yog tias sodium chloride, sodium trichloride, lossis tshuaj pleev yog siv los ua tshuaj tua kab mob, tag nrho cov alkalinity yuav tsum nyob rau hauv thaj tsam ntawm 100 txog 120 mg / L. Yog tias calcium, sodium, lossis lithium hypooxide siv los ua cov tshuaj tua kab mob, tag nrho cov alkalinity yuav tsum nyob rau hauv thaj tsam ntawm 80 txog 100 mg / L.

PH

pH hais txog lub zog ntawm acidic los yog alkaline tshuaj nyob rau hauv dej. pH 7,0 yog nruab nrab thiab pH ntau ntawm pas dej ua ke thiab spa dej yuav tsum nyob nruab nrab ntawm 7,0 thiab 7,8.
