1. Ultrafiltration (UF)
Ultrafiltration yog daim nyias nyias kev sib cais tshuab uas ua haujlwm hauv siab. Nyob rau hauv ib qho siab, me me molecular solutes thiab solvents dhau los ntawm kev tsim tshwj xeeb uas muaj qhov ntau thiab tsawg tus neeg siv lub ntsej muag sib luag yog khaws cia ntawm ib sab. Qhov no tso cai rau ib nrab huv ntawm macromolecular tshuaj.
Qhov zoo ntawm ultrafiltration:
Cov haujlwm yooj yim thiab tus nqi qis.
Tsis xav tau cov tshuaj ntxiv.
Cov kev ua haujlwm me me piv rau evaporation lossis khov-kom qhuav, uas tsis muaj theem hloov.
Tsis ua rau kub thiab txias lossis ph thiaj li hloov pauv, uas pab tiv thaiv tsis tau zoo, kev ua tsis tau, lossis auromolecules biological.
Ultrafiltration yog tsuas yog siv nyob rau hauv kev npaj ntawm biological macromolecules rau:
Kev nqis
Lub cev tuag
Kev xav ntsoov
Txwv:
Tsis tuaj yeem tsim cov hmoov kom qhuav.
Rau cov kev daws teeb meem muaj protein, nws ib txwm ua tiav tsuas yog 10% -50% siab.
Ultrafiltration yog haum rau ob qho tib si application. Tus yuam sij rau ultrafiltration lus dag nyob rau hauv daim nyias nyias nws tus kheej, uas los rau ntau hom thiab cov kev qhia tshwj xeeb yog nyob ntawm kev xav tau ua haujlwm.
2. Nanofiltration (nf)
Nanofiltration tso rau ntawm ultraFiltration thiab rov qab osmosis nyob rau hauv cov nqe lus ntawm kev saib xyuas tseeb. Nws yog feem ntau siv nyob rau hauv dej kho thiab muaj kev siv tshuaj ntsuam arealination.
Cov Nta Tseem Ceeb:
Kev cai lij choj noj qab haus ntev li 90%.
Tus nqi qis dua piv kom rov qab osmosis, ua rau nws muaj nyiaj ntau dua thaum ultra-siab dej huv tsis tas yuav tsum tau.
Nanofiltration yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau theem ntawm kev coj dawb huv nrog kev txuag nqi.
3. Rov Qab Osmosis (RO)
Rov Qab Osmosis yog ib daim nyias nyias nyias yog qhov sib cais siv tau los ntawm qhov sib txawv. Nws tau pib los ntawm Aerospace Technology kev tshawb fawb hauv Tebchaws Asmeskas thaum 1960s thiab tau txij li tau txais kev siv tau hauv kev thov neeg pej xeem.
Cov ntawv thov ntawm RO:
Kev tsim cov chaw dej, lim dej kom huv thiab cov dej distilled.
Cawv ntau thiab dej cawv cov txheej txheem.
Pretricatment ntawm dej rau cov chaw tshuaj thiab kev lag luam electronics.
Kev Lag Luam Tshuaj: Cov Kev Lag Luam, Kev Sib Cais, Kev Ua Yeeb Yam, thiab Kev Npaj Dej.
TOILER FEEWENING THIAB DESALINATION.
Kev Desalination ntawm Seasater thiab cov dej brackish.
Dej kho thiab dej lim dej hauv kev lag luam zoo li papermaking, electroplating, zas, thiab ntau dua.
Cov ntsiab lus tseem ceeb:
Rov Qab Osmosis muaj kev tsis lees txais ntsev ntau dua 99%, ua rau nws txoj kev xaiv uas nyiam tshaj plaws rau kev tsim cov dej siab.
