PVC daim nyias nyias yog cov khoom siv membrane nrog dej purification muaj nuj nqi. Nws tuaj yeem tshem tawm cov impurities thiab cov pa phem hauv dej, suav nrog cov khib nyiab pov tseg, macromolecular organic teeb meem thiab qee cov ions, los ntawm kev tshuaj xyuas lub cev thiab tshuaj ntsuam molecular, yog li txhim kho dej zoo. Nws qhov kev tshuaj ntsuam muaj peev xwm nyob ntawm qhov loj thiab cov duab ntawm daim nyias nyias pores. Txij li thaum lub ultrafiltration membrane ua los ntawm PVC muaj finer membrane pores, nws muaj peev xwm tshem tawm me me hais thiab organic teeb meem.
Tsis tas li ntawd, PVC daim nyias nyias kuj muaj cov tshuaj tiv thaiv zoo thiab tsis yooj yim eroded los ntawm cov tshuaj xws li acids, alkalis, thiab ntsev, uas ua rau nws hloov tau zoo thaum kho cov dej uas muaj tshuaj lom neeg. Nyob rau tib lub sijhawm, qhov chaw ntawm PVC daim nyias nyias yog du thiab tsis yooj yim ua raws li cov av, yog li nws yooj yim los ntxuav thiab tswj, thiab tuaj yeem tswj xyuas cov dej pom zoo.
Txawm li cas los xij, cov khoom siv PVC nws tus kheej tuaj yeem muaj ntxhiab tsw, uas tuaj yeem cuam tshuam qhov saj ntawm cov dej lim los ntawm nws. Yuav kom daws tau qhov teeb meem no, cov pa roj carbon activated feem ntau yog ntxiv tom qab PVC zaj duab xis kom nqus cov ntxhiab thiab txhim kho saj. Cov pa roj carbon activated muaj peev xwm adsorption muaj zog thiab tuaj yeem nqus cov pa phem hauv dej thiab tshem tawm cov hlau hnyav, cov tshuaj chlorine seem, cov tshuaj tsis haum tshuaj organic thiab lwm yam kuab paug.
Feem ntau, PVC daim nyias nyias muaj dav daim ntawv thov kev cia siab nyob rau hauv lub tshav pob ntawm dej purification. Txawm li cas los xij, xav txog cov teeb meem tsw nws tuaj yeem nqa tau, lwm cov ntaub ntawv lossis cov thev naus laus zis yuav tsum tau siv rau hauv cov ntawv thov tiag tiag txhawm rau txhim kho cov dej kom huv ntxiv.
