Yuav ua li cas los tiv thaiv lub membrane osmosis rov qab thaum lub sijhawm ua haujlwm ntawm lub cev?

Kev ua tiav ua ntej lawm; cov ntsiab lus ua haujlwm thaum lub sijhawm ua haujlwm tseem ceeb dua—ntau qhov kev puas tsuaj ntawm daim nyias nyias yog los ntawm "kev ua yuam kev ntawm tib neeg," xws li kev nce siab sai sai lossis kev rov zoo sai dhau. Nco ntsoov plaub lub ntsiab lus tseem ceeb no:

1. Kev nce siab qeeb: tus nqi yuav tsum yog ≤0.07 MPa/feeb. Thaum pib lub tshuab, tsis txhob qhib lub valve tam sim ntawd! Kev nce siab sai sai tuaj yeem ua rau cov khoom membrane poob siab, ua rau cov fibers membrane tsis sib haum thiab tawg ntawm cov nplaum sealing. Txoj hauv kev zoo yog maj mam qhib lub valve pub dej, cia lub siab nce qeeb qeeb mus rau tus nqi teem tseg.
2. Kev Tswj Xyuas Rov Qab Los: Rau ib qho module ≤15%, lub kaw lus ≤85%. Qhov siab dua ntawm tus nqi rov qab los, qhov siab dua ntawm cov pa phem concentration ntawm sab concentrated, ua rau muaj feem yuav scaled. Piv txwv li, yog tias tus nqi rov qab los ntawm ib module tshaj 15%, qhov concentration ntsev ntawm sab concentrated yuav ob npaug, sai sai tsim cov nplai uas thaiv cov qhov hws membrane. Kho qhov system rov qab los ntawm tus nqi raws li qhov zoo ntawm dej; rau cov dej ntsev siab, nws raug pom zoo kom txo nws kom haum.
3. Kev Ntxuav Raws Sijhawm: Yog tias muaj peb lub cim ceeb toom tshwm sim, nws yog lub sijhawm los ntxuav. Lub membrane tsis yog "tsis tas yuav saib xyuas." Thaum muaj kev ua qias tuaj txog qib twg, kev ntxuav yog qhov tsim nyog kom tsis txhob muaj kev puas tsuaj loj heev.

Cov dej tsim tawm ntau dua 10% ntawm tus nqi pib

TDS ntawm cov dej tsim tawm tau nce ntau dua 15% piv rau tus nqi pib

Qhov sib txawv ntawm lub siab hla daim nyias nyias nce ntau dua 15% piv rau tus nqi pib. Kev ntxuav yuav tsum tau ua raws li qhov sib law liag: thawj zaug ntxuav alkaline (kom tshem tawm cov organic matter thiab colloids), ua raws li kev ntxuav acid (kom tshem tawm cov calcium-magnesium scale thiab hlau oxides). Siv cov neeg sawv cev ntxuav tshwj xeeb thiab tsis txhob siv cov kua qaub lossis alkalis kom tiv thaiv kev puas tsuaj rau daim nyias nyias.

4. Kev Soj Ntsuam Lub Sijhawm Tiag Tiag: Ua raws li peb lub ntsiab lus tseem ceeb ntawm cov ntaub ntawv—Kev sau cov dej siab txhua hnub, TDS dej ntawm cov khoom, thiab tus nqi ntws ntawm cov kua. Yog tias muaj qhov tsis zoo tshwm sim (xws li TDS nce siab sai sai), tshawb xyuas qhov ua rau kom tiv thaiv cov teeb meem me me kom tsis txhob loj hlob mus ua qhov tsis zoo loj.
