Qhov sib txawv ntawm cov khoom siv ultrafiltration thiab cov khoom siv rov qab osmosis

Qhov sib txawv tseem ceeb ntawm ultrafiltration membrane thiab thim rov qab osmosis yog qhov sib txawv ntawm qhov pore loj. Lub pore loj ntawm lub nkoj ntawm thim rov qab osmosis membrane yog ib feem ntawm cov ultrafiltration membrane, thiab qhov pom tseeb ntawm rov qab osmosis membrane yog siab dua li ntawm ultrafiltration membrane. Ultrafiltration membrane piv rau thim rov qab osmosis membrane, rov qab osmosis membrane aperture yog ntau me dua li ultrafiltration membrane, rov qab osmosis membrane aperture yog 0.0001 micron, ultrafiltration membrane aperture yog 0.001 micron. Lub pore loj ntawm qhov rov qab osmosis membrane yog ib feem ntawm cov ultrafiltration membrane, yog li cov dej lim los ntawm cov rov qab osmosis membrane yog ntau ntshiab dua li ntawm cov ultrafiltration membrane.

Ultrafiltration membrane yog cov txheej txheem sib cais ntawm daim nyias nyias uas cov membrane muaj cov qauv ntxeem tau asymmetric. Cov txheej txheem pom yog cov txheej txheem kev daws teeb meem raws li lub hauv paus ntsiab lus ntawm lub zog sib txawv ntawm ob sab ntawm daim nyias nyias, kev ua haujlwm siab feem ntau yog 0.01 txog 0.03Mpa, thiab cov pore loj ntawm ultrafiltration membrane yog li 0.001 txog 0.01 microns. Lub interception molecular hnyav yog 1,000-500,000 daltons, yog li cov txheej txheem ultrafiltration membrane sib cais yog ib zaug suav hais tias yog txheej txheem kev sib cais ntawm lub cev.

Rov qab osmosis membrane yog ib qho khoom siv semi-permeable membrane nrog cov khoom tshwj xeeb tsim los ntawm kev simulating ib qho roj ntsha semi-permeable membrane. RO yog cov lus Askiv luv ntawm rov qab osmosis membrane, Suav yog lub ntsiab lus ntawm rov qab osmosis. Tag nrho cov dej ntws los ntawm qis mus rau siab. Thaum cov dej txias, cov dej yuav ntws los ntawm qhov siab mus rau qhov qis. Qhov no yog hu ua lub hauv paus ntsiab lus ntawm thim rov qab osmosis. Lub aperture ntawm rov qab osmosis membrane yog tsib labths (0.0001 micron) ntawm cov plaub hau tib neeg. Cov kab mob thiab cov kab mob loj dua 5,000 npaug, tso cai rau cov dej molecules nkaus xwb thiab qee cov ntxhia muaj txiaj ntsig zoo hla mus, thaum lwm cov impurities thiab cov hlau hnyav raug tshem tawm ntawm cov kav dej khib nyiab.

Lub aperture ntawm rov qab osmosis membrane yog 1/100 ntawm lub aperture ntawm lub ultrafiltration membrane, thiab qhov pom tseeb ntawm RO rov qab osmosis membrane nce mus txog 0.0001 micron. Txawm li cas los xij, qhov pom tseeb ntawm ultrafiltration membrane yog 0.001 microns. Yog li, rov qab osmosis daim nyias nyias tuaj yeem tshem tawm cov hlau hnyav, tshuaj tua kab, chloroform thiab lwm yam tshuaj lom neeg los ntawm dej, tab sis ultrafiltration membranes tsis tuaj yeem. Lub ultrafiltration membrane tshem tawm cov pa phem thiab cov kab mob, thiab thim rov qab osmosis tshem tawm lawv tag nrho.
