Txoj hauv kev zoo tshaj plaws kom nkag siab tias RO ua haujlwm li cas yog thawj zaug nkag siab lub tswv yim ntawm osmosis. Osmosis yog cov txheej txheem ntawm kev hla dej los ntawm ib qho semi-permeable membrane. Cov txheej txheem yuam dej txav los ntawm thaj tsam qis dua mus rau thaj tsam siab dua. Qhov no tuaj yeem pom tias cov nroj tsuag nqus dej li cas. Hauv kev rov qab osmosis, txawm li cas los xij, qhov rov qab yog qhov tseeb. Cov dej raug yuam kom txav mus rau qhov qis dua es tsis txhob muaj qhov nce ntxiv vim tias RO daim nyias nyias tiv thaiv cov kab mob kis los ntawm nws.
Qhov rov qab osmosis lim system muaj txiaj ntsig zoo hauv kev tshem tawm cov khoom tawg, cov khoom, thiab cov kuab tshuaj ntau dua li lwm txoj hauv kev pom vim tias lub siab thov thiab xaiv cov yam ntxwv ntawm daim nyias nyias. Nws siv cov txheej txheem semi-permeable membrane ua ke nrog cov lim roj carbon ntau. Cov no tau muab cais ua cov lim dej ua ntej lossis tom qab lim dej nyob ntawm seb lawv nyob qhov twg hauv cov txheej txheem pom. Cov dej uas muaj cov kab mob qis tshaj plaws yog hu ua permeate, thaum cov dej uas muaj qhov siab tshaj plaws yog hu ua brine lossis khib nyiab.
Cov theem ntawm RO system
Ib qho RO system muaj ib mus rau tsib theem pom. Feem ntau yog peb, plaub, lossis tsib-theem RO systems. Raws li qhov xav tau, 5-theem rov qab osmosis muab qhov siab tshaj plaws ntawm kev lim dej los ntawm kev rov qhia cov zaub mov tseem ceeb hauv qib tsib. Tag nrho cov txheej txheem rov qab osmosis ua haujlwm ntawm tib lub hauv paus ntsiab lus, uas suav nrog ib lossis ntau lub lim dej, cov lim roj carbon, thiab RO membrane.
Theem 1 – Sediment filter
Qhov no feem ntau yog thawj (prefilter) theem hauv RO filtration txheej txheem. Nws yog theem uas pom cov kab mob xws li cov av, cov khib nyiab, av, plua plav, thiab lwm yam sediments raug cais tawm ntawm cov dej los ntawm cov khoom siv dej (xws li dej los yog kais dej)
2nd / 3rd Theem - Pre-carbon lim thiab RO membrane
Cov pa roj carbon lim dej thiab RO membrane ua haujlwm kom tshem tawm cov tshuaj chlorine, Volatile Organic Compounds (VOCs), thiab lwm yam impurities uas yuav cuam tshuam rau xim lossis tsw ntawm dej. Cov theem no suav nrog cov lim dej ua ntej ua ntej, RO daim nyias nyias, thiab cov lim dej ua kom cov pa roj carbon activated.
Theem 4 - Semi-permeable membranes
Nyob rau theem no, ntxiv kev tshem tawm cov tshuaj phem (xws li fluoride, lead, thiab chromium) thiab lwm yam khoom tshwm sim vim dej raug yuam los ntawm semipermeable RO membrane. Cov theem no tshem tawm li ntawm 95 mus rau 98% ntawm Tag Nrho Cov Dej Sov (TDS) hauv dej.
Kauj Ruam 5 - Tom qab pom
Ntawm no, cov dej dhau los ntawm qhov kawg pom daim nyias nyias uas tshem tawm cov khoom ntxiv uas yuav tau dim tag nrho lwm cov theem pom. Feem ntau 5-theem RO tshuab siv cov txheej txheem remineralization ntxiv cov ntxhia tseem ceeb uas yuav raug tshem tawm rov qab rau hauv dej ntawm theem no. Nyob rau theem 5, peb cov RO dej lim siv granular activated carbon lim nrog ib tug tshwj xeeb sib tov ntawm carbon tau los ntawm burnt txiv maj phaub plhaub.
Kauj Ruam 6 - Txhim kho alkaline pom
Cov dej uas tsim nyob rau theem 5 ntawm RO txheej txheem yog ntshiab, noj qab nyob zoo, thiab muaj kev nyab xeeb rau haus. Txawm li cas los xij, qee cov lim dej RO suav nrog theem thib rau rau remineralization thiab alkalinization. Vim tias cov txheej txheem RO tau xav kom tau tshem tawm qee cov zaub mov los ntawm cov dej, theem 6 yog suav nrog ntxiv cov zaub mov tseem ceeb rov qab thaum tseem txo cov dej acidity kom nws alkaline. Alkaline dej muaj ntau cov txiaj ntsig, suav nrog kev ua kom dej ntau ntxiv thiab cov khoom antioxidant.
