Cov lim dej thiab cov dej lim dej yog ob hom khoom siv kho dej. Qhov sib txawv tseem ceeb ntawm lawv yog txoj kev thiab kev ua tau zoo ntawm kev kho dej. Qhov sib txawv ntawm ob yog piav qhia hauv qab no.
Ua ntej tshaj plaws, lub lim dej feem ntau yog cov cuab yeej yooj yim uas nws lub luag haujlwm tseem ceeb yog tshem tawm cov impurities loj hauv dej, xws li xuab zeb, av, hais, thiab lwm yam. Lub lim feem ntau muaj cov lim xov xwm, xws li lub vijtsam lossis cov khoom, uas cuam tshuam. thiab tshem tawm cov loj me me no impurities. Cov lim dej muaj cov nyhuv pom tsis zoo thiab feem ntau yog siv los tiv thaiv cov khoom siv hauv qab los ntawm kev puas tsuaj los ntawm cov khoom tsis zoo, lossis kho cov dej ua ntej kom muab cov dej nkag zoo dua rau cov khoom siv kho dej tom ntej.
Qhov thib ob, lub tshuab lim dej yog cov khoom siv kho dej ntau dua thiab siv tau zoo. Cov dej purifiers yog tsim los tshem tawm ntau yam teeb meem hauv dej, suav nrog cov kab mob, kab mob, kab mob, cov hlau hnyav, cov organic teeb meem, inorganic teeb meem, thiab lwm yam. Cov dej purifiers feem ntau siv cov cuab yeej ua ke, xws li ultrafiltration, thim rov qab osmosis, tshuaj tua kab mob ultraviolet, thiab lwm yam. ., kom ntseeg tau tias dej zoo mus txog qee cov qauv. Cov nyhuv pom ntawm lub tshuab lim dej yog qhov siab, uas tuaj yeem muab cov dej ntshiab huv thiab nyab xeeb dua thiab ua tau raws li qhov xav tau ntawm cov dej hauv tsev, kev lag luam, kev kho mob thiab lwm yam.
Tsis tas li ntawd, muaj qee qhov sib txawv ntawm cov qauv thiab kev siv cov lim dej thiab cov dej purifiers. Cov lim dej feem ntau yog me me, yooj yim rau nruab, thiab tuaj yeem siv nws tus kheej los yog ua ib feem ntawm kev kho dej loj dua. Cov dej purifiers feem ntau xav tau ntau qhov chaw thiab cov cuab yeej txhawb nqa, suav nrog cov kav dej nkag, cov kav dej tawm, cov khoom siv hluav taws xob, thiab lwm yam. Kev teeb tsa thiab siv cov tshuab lim dej kuj tseem nyuaj dua thiab xav tau qee yam kev txhawb nqa thiab kev saib xyuas.
Muaj qhov sib txawv ntawm cov lim dej thiab cov dej lim dej hauv cov ntsiab lus ntawm kev ua haujlwm, cov nyhuv, qauv thiab kev siv. Kev xaiv cov cuab yeej siv twg yog nyob ntawm cov kev xav tau tshwj xeeb ntawm cov dej zoo thiab kev kho mob. Rau cov tsev neeg zoo tib yam, kev siv cov lim dej tuaj yeem tiv thaiv kev nyab xeeb ntawm cov dej hauv tsev, tab sis rau cov kev xav tau zoo dua qub, xws li kev npaj cov dej haus, yuav tsum muaj lub tshuab lim dej kom zoo dua.
