Rov qab osmosis (RO) thev naus laus zis tau dhau los ua qhov kev xaiv nrov rau kev kho dej hauv ob qho tib si hauv tsev thiab kev lag luam. RO yog cov txheej txheem pom uas siv cov txheej txheem semi-permeable tshem tawm cov impurities ntawm dej. Tab sis dab tsi raws nraim yuav tshem tawm RO membrane?
Feem ntau, RO membranes muaj txiaj ntsig zoo ntawm kev tshem tawm ntau yam kab mob ntawm cov dej, suav nrog:
1. Dissolved minerals thiab ntsev: RO daim nyias nyias ua tau zoo ntawm kev tshem tawm cov minerals yaj, ntsev, thiab lwm yam inorganic compounds los ntawm dej. Cov no suav nrog calcium, magnesium, sodium, thiab chloride ions, thiab lwm yam. Los ntawm kev tshem tawm cov impurities, RO tuaj yeem pab txhim kho qhov saj thiab zoo ntawm cov dej haus, nrog rau kev ua kom lub neej ntev ntawm cov khoom siv dej.
2. Organic compounds: RO daim nyias nyias tuaj yeem tshem tawm ntau yam organic tebchaw los ntawm dej, suav nrog tshuaj tua kab, tshuaj tua kab, thiab lwm yam tshuaj. Qhov no ua rau RO yog cov cuab yeej tseem ceeb rau kev lag luam uas yuav tsum tau ntxuav cov dej kom huv rau cov txheej txheem tsim khoom, nrog rau cov tswv tsev muaj kev txhawj xeeb txog cov kab mob hauv lawv cov dej haus.
3. Cov kab mob thiab kab mob: RO daim nyias nyias muaj peev xwm tshem tau ntau hom kab mob thiab kab mob los ntawm dej. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis yog txhua lub tshuab RO yog tsim los tshem tawm cov kab mob microbiological, thiab kev kho mob ntxiv yuav tsum tau muaj nyob rau qee kis.
4. Cov hlau hnyav: Nyob ntawm hom RO membrane siv, nws kuj tseem tuaj yeem tshem tau qee yam hlau hnyav los ntawm dej, xws li txhuas, arsenic, thiab mercury. Qhov no tuaj yeem yog qhov tseem ceeb tshwj xeeb rau cov tsev neeg uas muaj cov kav dej laus lossis hauv thaj chaw uas muaj cov hlau hnyav hnyav.
5. Tag nrho cov kuab tshuaj yaj (TDS): RO daim nyias nyias muaj peev xwm txo tau tag nrho cov yaj yaj (TDS) hauv dej, uas yog hais txog cov concentration ntawm ntau cov kuab tshuaj yaj thiab ntsev. Kev txo TDS feem ntau yog lub hom phiaj tseem ceeb rau kev kho dej, vim TDS qib siab tuaj yeem ua rau muaj teeb meem xws li kev tsim cov nplai thiab dej tsis zoo.
Hauv cov ntsiab lus, RO daim nyias nyias muaj peev xwm tshem tawm ntau yam impurities los ntawm dej, ua rau lawv muaj zog rau kev kho dej. Txawm li cas los xij, tsis yog txhua lub tshuab RO raug tsim sib npaug, thiab qhov ua tau zoo ntawm RO membrane yuav nyob ntawm ntau yam, suav nrog qhov zoo ntawm cov dej, hom membrane siv, thiab cov kab mob tshwj xeeb uas muaj nyob hauv dej. Nws yog ib qho tseem ceeb uas yuav tau sab laj nrog tus kws kho dej kom txiav txim siab txog kev kho mob uas tsim nyog rau koj cov kev xav tau tshwj xeeb.
