Nyob rau hauv lub tshav pob ntawm kev sib cais niaj hnub thiab kev huv, kauv qhov txhab daim nyias nyias, nrog lawv cov qauv compact, siab flux, thiab muaj zog adaptability, tau dhau los ua ib qho tseem ceeb hauv kev lag luam xws li kev kho dej, khoom noj khoom haus thiab tshuaj, thiab tshuaj. Lawv lub hauv paus ntsiab lus tsim yog ua raws li cov kev cai tas mus li ntawm cov txheej txheem sib cais membrane. Los ntawm cov txheej txheem winding meej, cov ntawv sib cais, cov ntaub ntawv txhawb nqa, thiab cov dej ntws channel tau muab tso rau hauv ib qho qauv, txhim kho kev sib cais thiab kev ua haujlwm yooj yim.
Cov txheej txheem tseem ceeb ntawm cov kab mob kis kab mob muaj ntau cov txheej txheem ntawm cov ntaub ntawv ua haujlwm thiab ntws tawm -cov kev taw qhia meshes, alternated stacked thiab qhov txhab nyob rau hauv nruab nrab lub raj xa dej. Cov kua pub nkag mus rau hauv lub membrane module nyob rau hauv siab. Cov kuab tshuaj los yog cov molecules me me uas permeate daim nyias nyias daim ntawv permeate dej, thaum loj molecules los yog ions uas tau khaws cia yog tawm nrog cov concentrate, ua kom muaj kev sib cais. Cov qauv tsim no ua rau kom muaj txiaj ntsig zoo ntawm daim nyias nyias thiab txo cov concentration polarization los ntawm kev kub ntxhov, ua kom lub sijhawm ntev - ua haujlwm ruaj khov. Piv rau phaj-thiab-thav duab thiab hollow fiber ntau daim nyias nyias, kauv lub qhov txhab daim nyias nyias ua rau cov ntaub so ntswg siv rau ib chav tsev ntim ntau tshaj 30%, ua rau lawv tshwj xeeb tshaj yog haum rau loj -scale kev kho mob tsis tu ncua scenarios.
Los ntawm daim ntawv thov kev xav, kauv qhov txhab membrane tshuab tau nkag mus rau ntau qhov chaw: hauv kev kho dej, rov qab osmosis (RO) thiab nanofiltration (NF) kauv lub qhov txhab daim nyias nyias tuaj yeem tshem tawm cov hlau hnyav, ntsev, thiab cov kab mob, ua rau lawv cov kev daws teeb meem rau seawater desalination thiab ultrapure dej ntau lawm; nyob rau hauv kev lag luam khoom noj khoom haus, lawv yog siv rau cov kua txiv kom meej thiab whey protein rov qab, sib npaug zoo preservation thiab kev pab cuam efficiency; nyob rau hauv biopharmaceutical teb, acid- thiab alkali-resistant, siab -precision kauv qhov txhab daim nyias nyias yog siv rau kev siv tshuaj purification thiab tshuaj lom neeg sib cais. Tsis tas li ntawd, rau cov xwm txheej nyuaj xws li siab- dej qab ntsev thiab cov kuab tshuaj organic rov qab, tshwj xeeb- cov khoom siv kauv lub qhov txhab daim nyias nyias (xws li fouling-tiv taus thiab siab- kub- hom resistant) yog txuas ntxiv nthuav dav cov ciam teb thev naus laus zis.
Nrog rau cov qauv nruj zuj zus ntxiv thiab kev xav tau ntau ntxiv rau cov khoom siv rov ua dua tshiab, kauv lub qhov txhab membrane thev naus laus zis tau hloov zuj zus mus rau qis zog noj, fouling tsis kam, thiab kev ua haujlwm ntse. Kev sib xyaw ua ke ntawm cov khoom siv tshiab membrane tshawb fawb thiab kev txhim kho nrog kev tsim kho kom zoo dua qub yuav nthuav tawm nws lub peev xwm hauv kev txuag hluav taws xob thiab txo qis emission, dhau los ua lub hauv paus tseem ceeb thev naus laus zis txhawb kev tsim ntsuab thiab kev tsim kho kom ruaj khov.
