Kev lag luam dej lim dej muaj ntau yam ua ntej- lim, feem ntau suav nrog PP paj rwb, ceramic, activated carbon, thiab rov qab osmosis lim. Cov lim dej no feem ntau tshem tawm impurities, tsw, thiab cov khoom tsis zoo los ntawm cov dej, txhim kho cov dej zoo.
PP paj rwb lim yog ib hom pre{0}}filter. Lawv feem ntau yog siv los tshem tawm cov khoom tsis huv loj ntawm cov dej, xws li sediment thiab xeb. Kev pom tseeb ntawm PP paj rwb lim yog feem ntau ntawm 5-50 microns, zoo tiv thaiv kev txhaws ntawm cov lim dej tom ntej thiab txuas ntxiv lub neej ntawm lub tshuab lim dej.
Ceramic lim yog tsim los ntawm cov khoom siv ceramic thiab feem ntau yog siv los tshem tawm cov kab mob, kab mob, thiab lwm yam kab mob hauv dej. Qhov pom tseeb ntawm cov ntxaij lim dej ceramic feem ntau yog nyob nruab nrab ntawm 0.1-0.5 microns, tshem tawm cov kab mob zoo thiab txhim kho dej nyab xeeb.
Cov lim dej ua kom cov pa roj carbon activated yog ua los ntawm cov khoom siv roj carbon activated thiab feem ntau yog siv los tshem tawm cov ntxhiab thiab cov khoom tsis zoo los ntawm dej, xws li chlorine thiab organic teeb meem. Kev pom tseeb ntawm cov lim dej lim dej feem ntau yog nyob nruab nrab ntawm 10-50 microns, tshem tawm cov ntxhiab tsw thiab cov khoom tsis zoo thiab txhim kho saj thiab kev nyab xeeb ntawm cov dej.
Lub lim dej rov qab osmosis yog lub lim ua los ntawm semi-permeable membrane technology, feem ntau yog siv los tshem tawm cov ntsev yaj, cov hlau hnyav, cov khoom organic, thiab lwm yam khoom tsis zoo los ntawm dej. Rov qab osmosis cov ntxaij lim dej muaj qhov pom tseeb heev, ncav cuag li 0.0001 microns, tshem tawm cov khoom tsis zoo thiab txhim kho dej nyab xeeb.
Qhov sib txawv ntawm cov khoom ua ntej -filters nyob rau hauv lawv qhov kev pom tseeb, pom cov nyhuv, thiab siv ntau yam. Thaum xaiv lub lim ua ntej -, nws yog ib qho tsim nyog los xaiv ib qho haum raws li koj xav tau thiab dej zoo. Kev hloov lim dej tsis tu ncua kuj tseem yog qhov tseem ceeb los xyuas kom muaj kev ua haujlwm zoo ntawm lub tshuab lim dej.
