5 Lub Tswv Yim Kom Ntev Tau Lub Neej RO Membrane Thiab Txuag Cov Nqi

1. Xyuas kom meej tias kev kho dej pub ua ntej zoo

Qhov zoo ntawm cov dej pub yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev ua haujlwm thiab lub neej ntawm RO membrane. Cov tshuaj tsis xav tau hauv cov dej nyoos, xws li cov khoom seem, colloids, cov organic matter, thiab chlorine, tuaj yeem ua rau puas tsuaj rau daim nyias nyias. Yog li ntawd, kev siv cov txheej txheem ua ntej kho yog qhov tseem ceeb.

Ua ntej, nruab ib lub lim dej kom tshem tawm cov khoom loj xws li xuab zeb, av nplaum, thiab xeb, uas tuaj yeem khawb qhov saum npoo ntawm daim nyias nyias. Qhov thib ob, siv lub lim dej carbon activated los tshem tawm cov chlorine thiab cov organic compounds - chlorine, tshwj xeeb, tuaj yeem oxidize cov khoom siv daim nyias nyias, ua rau kev ua haujlwm desalination poob qis sai. Rau cov dej uas muaj turbidity siab lossis cov ntsiab lus colloidal, ntxiv cov kauj ruam coagulation thiab flocculation tuaj yeem txhim kho kev ua haujlwm ua ntej. Los ntawm kev ua kom ntseeg tau tias cov dej pub ua tau raws li qhov yuav tsum tau nkag ntawm RO membrane, koj tuaj yeem txo qhov kev pheej hmoo ntawm daim nyias nyias fouling thiab tso lub hauv paus ruaj khov rau kev ncua nws lub neej kev pabcuam.

2. Tswj Xyuas Cov Kev Ua Haujlwm Kom Zoo

Kev siv lub tshuab RO hauv qhov ntau thiab tsawg uas tau pom zoo yog qhov tseem ceeb heev kom tsis txhob muaj kev ntxhov siab ntau dhau rau ntawm daim nyias nyias. Cov yam ntxwv tseem ceeb uas yuav tsum tau saib xyuas suav nrog kev ua haujlwm siab, kub, thiab tus nqi rov qab los.

Kev ua haujlwm siab dhau heev tuaj yeem ua rau daim nyias nyias puas tsuaj sai dua thiab ua rau siv hluav taws xob ntau dua. Ib txwm ua raws li cov lus qhia ntawm cov chaw tsim khoom kom tau qhov siab zoo tshaj plaws. Qhov kub kuj cuam tshuam rau kev ua haujlwm ntawm daim nyias nyias - qhov kub siab dua tuaj yeem txhim kho cov dej ntws tab sis kuj tseem yuav ua rau kom muaj kev sib sau ua ke thiab ua rau muaj kev qias neeg. Yog li ntawd, nws yog qhov tsim nyog los tswj qhov kub ntawm cov dej pub rau hauv qhov ntau thiab tsawg tsim nyog, feem ntau ntawm 25 ° C thiab 35 ° C. Tsis tas li ntawd, qhov rov qab los (qhov sib piv ntawm cov dej khoom rau cov dej pub) yuav tsum tsis txhob siab dhau. Qhov rov qab los ntawm kev ua haujlwm siab tuaj yeem ua rau muaj cov ntsev thiab cov khoom tsis huv ntawm qhov chaw ntawm daim nyias nyias, ua rau muaj kev pheej hmoo ntawm kev sib sau ua ke. Kev kho qhov rov qab los ntawm kev ua haujlwm raws li qhov zoo ntawm dej thiab kev tsim qauv tuaj yeem sib npaug ntawm kev ua haujlwm ntawm cov dej thiab kev tiv thaiv daim nyias nyias.

3. Siv Cov Txheej Txheem Ntxuav Kom Huv Si Thiab Ua Kom Zoo

Txawm tias tau kho ua ntej zoo lawm los xij, qhov ua rau daim nyias nyias lwj kuj tseem yuav tshwm sim raws sijhawm. Kev ntxuav raws sijhawm thiab raug tuaj yeem tshem tawm cov tshuaj ua qias thiab rov ua kom daim nyias nyias ua haujlwm tau zoo dua. Txawm li cas los xij, kev ntxuav tsis raug tuaj yeem ua rau daim nyias nyias puas tsuaj ntau dua, yog li nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem ntxuav kev tshawb fawb.

Ua ntej, tsim kom muaj ib lub sijhawm tu vaj tse tsis tu ncua raws li cov cim qhia kev ua haujlwm ntawm lub kaw lus, xws li kev txo qis ntawm cov dej ntws, kev nce siab ntawm kev ua haujlwm, lossis kev txo qis ntawm kev tshem dej ntsev. Qhov thib ob, xaiv cov tshuaj ntxuav kom haum raws li hom kev ua qias tuaj - piv txwv li, siv cov tshuaj ntxuav acidic kom tshem tawm cov nplai inorganic (xws li calcium carbonate) thiab cov tshuaj ntxuav alkaline kom tshem tawm cov organic fouling thiab biofouling. Tsis txhob siv cov tshuaj lom neeg uas tsis sib xws nrog cov khoom siv membrane. Thaum lub sijhawm ntxuav, tswj qhov concentration ntawm cov tshuaj ntxuav, kub, thiab lub sijhawm ntxuav kom nruj. Tom qab ntxuav, yaug lub membrane kom huv si nrog dej huv kom tshem tawm cov tshuaj ntxuav seem, uas tuaj yeem ua rau puas tsuaj mus sij hawm ntev yog tias tso tseg.

4. Saib Xyuas thiab Tswj Xyuas Qhov Zoo ntawm Dej tas mus li

Kev saib xyuas tas li ntawm cov dej pub, cov dej tsim tawm, thiab cov dej sib xyaw zoo tuaj yeem pab nrhiav tau cov teeb meem thaum ntxov thiab ua cov kev ntsuas tiv thaiv raws sijhawm. Cov cim qhia tseem ceeb suav nrog qhov turbidity, pH tus nqi, chlorine content, tag nrho cov khoom yaj (TDS), thiab conductivity.

Nruab cov cuab yeej saib xyuas online kom taug qab cov cim qhia no hauv lub sijhawm tiag tiag. Piv txwv li, lub ntsuas turbidity tuaj yeem ceeb toom koj txog kev nce ntxiv ntawm cov khoom seem hauv cov dej pub, ua rau koj kuaj xyuas thiab hloov lub lim dej ua ntej kho. Lub ntsuas pH tuaj yeem pab tswj cov pH dej pub kom nyob hauv qhov ntau zoo tshaj plaws (feem ntau yog 6.5 txog 8.5) kom tiv thaiv kev xeb lossis kev tawg ntawm daim nyias nyias. Kev kuaj xyuas TDS thiab kev coj ua ntawm cov dej khoom tsis tu ncua tuaj yeem cuam tshuam txog kev ua haujlwm ntawm daim nyias nyias - txhua qhov nce sai sai yuav qhia txog kev puas tsuaj lossis kev ua qias tuaj ntawm daim nyias nyias. Los ntawm kev ceev faj txog kev hloov pauv dej zoo, koj tuaj yeem daws cov teeb meem ua ntej lawv nce siab, yog li tiv thaiv daim nyias nyias thiab txo cov nqi kho.

5. Txais Yuav Kev Kaw thiab Khaws Cia Kom Zoo

Yog tias kaw thiab khaws cia RO tsis raug, nws yuav ua rau daim nyias nyias puas tsuaj loj heev, tshwj xeeb tshaj yog thaum tsis ua haujlwm ntev. Yog li ntawd, kev ua raws li cov txheej txheem kaw thiab khaws cia kom raug yog qhov tseem ceeb kom ntev lub neej ntawm daim nyias nyias.

Thaum kaw lub tshuab rau lub sijhawm luv luv (tsawg dua ib lub lim tiam), yaug lub membrane nrog cov dej khoom kom tshem tawm cov khoom seem, tom qab ntawd ua kom lub membrane ntub kom tiv thaiv kev qhuav - kev ziab tuaj yeem ua rau puas tsuaj rau lub membrane qhov porous qauv. Yog tias kaw lub sijhawm ntev (ntau tshaj ib lub lim tiam), siv cov tshuaj preservative (xws li sodium bisulfite kua) kom muab lub membrane rau hauv. Xyuas kom tseeb tias qhov concentration ntawm preservative yog tsim nyog thiab hloov cov tshuaj tsis tu ncua kom tiv thaiv kev loj hlob ntawm cov kab mob. Ua ntej rov pib dua lub tshuab, yaug lub membrane kom huv si nrog dej huv kom tshem tawm cov tshuaj preservative, xyuas kom meej tias cov dej khoom ua tau raws li qhov yuav tsum tau ua.

Xaus lus

Kev ua kom lub neej ntawm cov RO membranes ntev dua thiab txo cov nqi khiav lag luam tsis yog ib txoj haujlwm nyuaj - nws yuav tsum tau ua kom tiav kev kho ua ntej kom zoo, tswj hwm cov kev ua haujlwm kom zoo, ntxuav tas li, saib xyuas cov dej kom zoo, thiab kaw thiab khaws cia kom raug. Los ntawm kev ua raws li tsib lub tswv yim no, koj tsis tsuas yog ua kom lub neej ntawm RO membranes ntev dua, txo qhov zaus ntawm kev hloov pauv kim, tab sis kuj txhim kho qhov ua tau zoo ntawm RO system, txo cov nqi zog thiab kev saib xyuas. Kev siv sijhawm thiab kev rau siab rau cov kev ntsuas tiv thaiv no yuav coj cov txiaj ntsig kev lag luam mus sij hawm ntev thiab xyuas kom meej tias koj lub tshuab kho dej ua haujlwm ruaj khov thiab txhim khu kev qha.
