Ultrafiltration membrane thiab thim rov qab osmosis membrane yog ob qho tib si lim membrane cov khoom lag luam uas ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev sib cais membrane, feem ntau yog siv hauv kev kho dej.Ob lub lim membrane cov khoom no yog siv los ntawm ntau tus neeg siv uas xav tau kev kho dej.Txawm hais tias ob qho tib si ultrafiltration membranes thiab thim rov qab osmosis membranes tau siv hauv kev kho dej, muaj ntau qhov sib txawv ntawm lawv.
Qhov sib txawv ntawm ultrafiltration membrane thiab thim rov qab osmosis membrane yog qhov loj heev, suav nrog tab sis tsis txwv rau: qhov sib txawv ntawm qhov hnyav molecular ntawm kev cuam tshuam, qhov sib txawv ntawm cov dej kom tsawg, qhov sib txawv ntawm daim ntawv thov, qhov sib txawv ntawm cov dej ua tau zoo thiab qhov sib txawv hauv nqe.Cov kev sib txawv no tau piav qhia raws li hauv qab no:
1. Qhov sib txawv ntawm qhov hnyav molecular ntawm kev cuam tshuam.Lub interception molecular hnyav ntawm qhov rov qab osmosis membrane yog> 100, uas tuaj yeem cuam tshuam tag nrho cov organic teeb meem, yaj ntsev, ions thiab lwm yam khoom uas muaj qhov hnyav molecular ntau dua 100, kom cov dej molecules thiab cov khoom uas muaj qhov hnyav molecular tsawg dua 100 tuaj yeem dhau mus;Qhov hnyav molecular ntawm ultrafiltration membrane yog> 10000, uas tuaj yeem raug dai rau hauv biofilms, proteins, macromolecular tshuaj, kom cov ntsev inorganic, me me molecular tshuaj thiab dej tuaj yeem dhau mus.Los ntawm qhov sib txawv ntawm qhov hnyav molecular ntawm kev cuam tshuam, nws tuaj yeem pom tias qhov tseeb ntawm qhov rov qab osmosis membrane yog ntau dua li ntawm ultrafiltration membrane.
2. Qhov sib txawv ntawm cov dej.Feem ntau, cov turbidity yuav tsum tau ntawm ultrafiltration membranes rau cov dej haus yog tsawg tshaj li cov reverse osmosis membranes, thiab muaj me ntsis txawv nyob rau hauv cov dej haus kub thiab pH.Cov kev xav tau ntawm ultrafiltration membrane yog qis dua li cov rov qab osmosis membrane, yog li cov ultrafiltration membrane tuaj yeem tiv taus cov dej nrog cov dej tsis zoo.
3. Qhov txawv ntawm daim ntawv thov teb.Txawm hais tias ob qho tib si ultrafiltration membrane thiab thim rov qab osmosis membrane yog cov lim dej uas ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev sib cais ntawm daim nyias nyias, lawv txawv heev hauv daim ntawv thov vim muaj ntau yam xws li pom qhov tseeb, kev tsim qauv, thiab cov yam ntxwv ntawm cov qauv.Rov qab osmosis membrane feem ntau yog siv rau hauv dej brackish desalination, kev npaj dej ntshiab, kev sib cais tshwj xeeb thiab lwm yam kev lag luam, ultrafiltration membrane feem ntau yog siv hauv kev kho dej phwj, dej ntshiab pretreatment thiab tsim cov dej haus thiab lwm yam kev lag luam.
4. Qhov sib txawv ntawm cov dej ua tau zoo.Qhov zoo ntawm cov dej tsim yog feem ntau cuam tshuam nrog kev pom tseeb ntawm cov lim membrane thiab cov dej kom zoo, qhov rov qab osmosis membrane tsis tsuas yog siab dua li cov ultrafiltration membrane hauv kev pom tseeb, nws cov dej kom tsawg kuj zoo dua li ultrafiltration membrane. , yog li cov dej zoo ntawm qhov rov qab osmosis membrane zoo dua li ultrafiltration membrane, los yog tsawg impurities, huv dua.
5. Nqe sib txawv.Ultrafiltration membranes thiab thim rov qab osmosis membranes muaj ntau hom, tab sis feem ntau, tus nqi ntawm rov qab osmosis daim nyias nyias yog kim dua li ultrafiltration membranes.
Toption Machinery yog cov chaw tsim khoom ntawm cov khoom siv kho dej.Toption Machinery cov khoom siv rov qab osmosis dej kho thiab cov khoom siv kho dej ultrafiltration tau lees paub thiab qhuas los ntawm ntau tus neeg siv khoom rau nws cov cuab yeej siv siab heev, cov ntaub ntawv zoo, kev ua haujlwm ruaj khov thiab kev pab cuam tom qab muag zoo.Nyob rau hauv lub neej yav tom ntej, Toption Machinery yuav ntxiv dag zog rau kev tshawb fawb thiab kev loj hlob, tas li txhim kho cov khoom ua tau zoo thiab cov kev pab cuam, thiab muab cov neeg muas zaub nrog ntau cov khoom siv kho dej zoo, thiaj li los txhawb txoj kev loj hlob ntawm Tuam Tshoj cov khoom siv kho dej kev lag luam.
