Tom qab siv RO dej purifier rau ib ntus, nws muaj peev xwm ua rau cov impurities tuaj yeem txhaws hauv RO tsev thiab ntawm RO membrane. Yog li, nws yog qhov pom zoo kom ntxuav cov vaj tsev thiab cov membrane feem ntau thaum siv RO system. Nws yog ib tus cwj pwm zoo uas yuav tsum nco ntsoov xyuas kom cov membrane thiab vaj tsev nyob huv si txhua lub sijhawm, vim tias qhov zaus ntawm RO daim nyias nyias tau ntxuav yog muaj feem xyuam nrog cov dej zoo. Hauv tsab xov xwm no, peb yuav muab cov ncauj lus kom ntxaws txog yuav ua li cas ntxuav lossis nyem RO daim nyias nyias hauv tsev.
Thaum cuam tshuam nrog cov dej tawv, ntau cov ntsev, cov zaub mov, thiab cov khoom txawv teb chaws uas tsis xav tau tuaj yeem sib sau ua ke thiab cuam tshuam cov dej ntws, uas ua rau qis qis ntawm daim nyias nyias. Qhov no tuaj yeem ua rau txo qis ntawm qhov tsis lees paub nrog rau kev txo qis hauv cov dej hauv koj lub cev. Yog li, ntxuav koj daim nyias nyias yog ib kauj ruam yooj yim hauv kev tswj koj lub cev thiab xyuas kom koj tau txais cov dej zoo tshaj plaws txhua lub sijhawm.
Muaj ob hom tshuaj ntxuav: ib qho rau ntxuav cov calcium thiab magnesium ions, uas yog siv nyob rau hauv cov cheeb tsam uas muaj dej zoo, thiab lwm yam rau tu cov organic tebchaw. Nws tuaj yeem tsim los ntawm kos hauv tsev lossis yuav npaj ua tiav. Txhawm rau ua cov txheej txheem ntxuav no, xyuas kom tseeb tias koj muaj PH tester. Yog vim li cas rau qhov no yog tias thaum ntxuav lub membrane, peb siv citric acid los yog hydrochloric acid; citric acid yog tsim los rau hauv 2% tov, yog li ntawd tus nqi PH yuav tsum nyob ib ncig ntawm 2 - 3.Yog ntxuav cov organic teeb meem, siv 0.1% sodium hydroxide ntxiv rau 0.025% sodium dodecyl sulfonate, sib tov nrog dej huv thiab kho tus nqi PH mus txog 11-12.
Tsuas yog ib qho hnyav tuaj yeem siv rau ib lub sijhawm, tsis yog ob qho tib si hnyav. Mixed-siv yuav tsis tsuas yog tsis muaj kev cuam tshuam tab sis kuj ua rau irreversible kev puas tsuaj rau RO membrane. Yog tias koj xav siv cov kuab tshuaj ob qho tib si, thawj zaug ntxuav cov membrane nrog calcium thiab magnesium ion ntxuav cov tshuaj rau li ob teev; Tom qab ntawd yaug nrog dej huv, ua raws li cov tshuaj ntxuav cov organic. Yog lawm, yog tias qhov txhaws hnyav dhau lawm, tsuas yog siv lub twj tso kua mis kom tso cov reagent rau hauv RO membrane plhaub, tsau nws rau ob teev, thiab tom qab ntawd ntxuav nws. Tom qab ntxuav, yaug lub membrane nrog dej huv.
Txawm hais tias kev ntxuav RO daim nyias nyias yog ib qho kev coj ua zoo, nws tsis pom zoo kom ntxuav cov membrane tsis tu ncua yog tias nws ua haujlwm tsis zoo. Peb thov kom hloov daim nyias nyias txij li kev ntxuav cov membrane tuaj yeem nyuaj yog tias koj tsis paub txog cov tshuaj lossis cov kev daws teeb meem uas siv hauv cov txheej txheem.
