Dej ua haujlwm nyuaj yog vim muaj lub siab cov ntsiab lus ntawm alkaline ntiaj teb hlau ntsev, xws li calcium thiab magnesium, yaj tag hauv nws. Qhov no yog qhov tsim kev puas tsuaj rau cov khoom siv hauv tsev, feem ntau yog tshuab ntxhua khaub ncaws. Koj tuaj yeem tso tawm ntawm cov khoom ntiag tug ntawm cov dej no hauv ntau txoj kev.
Haus dej nyuaj lossis dej muag yog qhov tsim kev puas tsuaj rau koj kev noj qab haus huv. Qib ntsev ntau tuaj yeem tsim cov pob zeb tso zis, thiab cov ntsev qis tsuas yog nce me ntsis kom muaj kev pheej hmoo ntawm cov kab mob plawv. Lub saj ntawm dej caij nplooj ntoos hlav yog txiav txim siab los ntawm nws qhov nyuaj.
Zog tawv thiab muag dej
Qhov nyuaj thiab muag ntawm dej yog nyob ntawm theem ntawm ntsev cov ntsiab lus hauv nws. Hauv thawj kis nws yog tus siab, nyob rau hauv lub thib ob nws tsis tseem ceeb. Cov ntsiab lus no tshwm sim, txawm hais tias, vim yog cov yam ntxwv uas dej muaj rau ntawm qee yam. Yog tias koj ntxuav lawv hauv dej nyuaj, cov ntaub nws tus kheej yuav zoo ib yam. Yog tias nws muag muag, ces cov khaub ncaws ua muag muag.
Dej hardness yog ib ntus thiab ruaj khov. Thawj zaug muaj cov calcium thiab calcium bicarbonate, qhov thib ob - lwm yam ntsev. Cov no yog cov feem ntau sulfates thiab chlorides ntawm cov tib cov qub. Lawv raug tso tawm thaum dej npau npau.
Siv dej tawv qhuav tawm ntawm koj cov tawv nqaij thaum koj ntxuav koj lub ntsej muag. Ua npuas ncauj yog qhov tsis zoo tsim hauv nws, thiab nws siv ua rau kev tsim nplai. Tib lub sijhawm, cov dej mos ua rau xeb, thaum bicarbonate hardness, ntawm qhov tsis sib thooj, tsis pub nws tsim.
Cov ntsev muaj nyob hauv cov dej ntuj kuj sib txawv thiab. Nws nce thaum lub sijhawm dej evaporation, thiab poob qis thaum lub caij los nag thiab lub sijhawm daus.
Txoj hauv kev tshem tawm txhav
Thawj txoj kev thiab qhov yooj yim tshaj plaws yog cua sov. Nws tsuas yog tsim nyog los rhaub dej, vim tias ntawm qhov uas tsis ruaj tsis khov ntawm magnesium thiab calcium yuav pib decompose. Qhov no yuav tshem tawm qhov nyuaj ib ntus ntawm dej. Ntxiv mus, nplai yuav yog qhov tshwm sim los ntawm kev ua kom tsis qab ntsev.
Koj tuaj yeem tseem sim sim reagent dej softening. Nws yog ib qho tsim nyog yuav tau ntxiv cov dej qab zib tshauv lossis slaked txiv qaub rau nws. Hauv cov qauv no, cov ntsev ntsev thiab calcium uas tau hloov pauv mus ua ib qho tsis txaus ntseeg thiab muaj qhov sib xyaw ua kom haum. Sodium orthophosphate yog suav hais tias yog txoj hauv kev zoo tshaj kom tshem tawm cov tawv tawv. Nws yog ib feem ntawm ntau tsev neeg thiab cov khoom lag luam.
Lwm txoj hauv kev yuav tsum yog cationization. Ib qho siv hluav taws xob ion-pauv kev tswj hwm tus nqi yuav tsum muab tso rau hauv dej. Cov feem ntau siv cov txauv ion pauv. Ntawm kev sib cuag nrog dej, nws nqus cov cations ntsev. Coj lawv mus deb ntawm calcium, magnesium, hlau thiab manganese, nws muab sodium thiab hydrogen ions, thiab cov dej ua mos.
Rov qab osmosis tuaj yeem siv tau. Nws yog qhov tsim nyog kom dhau dej los ntawm cov kab mob semi-permeable. Qhov no yuav tshem tawm cov ntsev ntau ntawm cov dej, suav nrog cov uas ua lub luag haujlwm txog qhov nyuaj. Qhov ua tau zoo ntawm hom no qee zaum nce mus txog yuav luag 100%.
