Muaj ob hom tshuaj ntxuav, ib qho yog siv rau kev ntxuav cov calcium thiab magnesium ions, qhov no yog siv rau hauv cov chaw uas muaj dej ntau dhau, thiab lwm qhov yog siv los ntxuav cov organic. Nws tuaj yeem npaj tau los ntawm koj tus kheej, lossis koj tuaj yeem mus rau Amazon los yuav npaj ua.
Txhawm rau ntxuav cov calcium thiab magnesium ions, koj tuaj yeem siv citric acid lossis hydrochloric acid, citric acid tau npaj rau hauv cov tshuaj ntawm 2%, (hydrochloric acid hloov mus rau 0.2%) PH tus nqi yog khaws cia ntawm li 2 ~ 3, nco ntsoov siv daim ntawv xeem PH los kuaj tus nqi PH ua ntej siv.
Yog tias 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 txog li 11-12.
Ua tib zoo saib thaum ntxuav RO membrane:
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 nrog calcium thiab magnesium ion tshuaj ntxuav, feem ntau yog li ob teev me me; Tom qab kev ntxuav tiav lawm, yaug nrog dej huv, thiab tom qab ntawd yaug nrog cov tshuaj ntxuav organic.
Feem ntau hais lus, tom qab ntxuav nrog ob txoj kev daws teeb meem, cov dej tsim tawm ntawm RO membrane yuav nce ntxiv.
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.
