Vim lawv cov qauv tsim tshwj xeeb thiab kev ua tau zoo, siab - cov ntaub ntawv siab ua lub luag haujlwm tseem ceeb hauv cov tshuab sib cais membrane, tuav cov haujlwm sib cais uas xav tau siab osmotic siab, siab concentration, thiab siab purity. Lawv daim ntawv thov nthuav dav kev tsim kho dej, kev kho dej khib nyiab, biopharmaceutical purification, thiab lub zog-txog teb, ua rau lawv yog ib qho tseem ceeb thev naus laus zis txhawb kev tsim khoom huv si thiab kev siv cov khoom siv.
Hauv kev kho dej, siab - cov ntaub ntawv siab yog ib qho tseem ceeb ntawm cov dej hiav txwv loj - kev desalination. Nrog rau lawv txoj haujlwm ruaj khov nyob rau hauv kev kub ntxhov ntawm ntau lub megapascals thiab ntau dua, rov qab osmosis siab - cov ntaub ntawv siab tuaj yeem kov yeej qhov siab osmotic siab ntawm cov dej hiav txwv, hloov cov dej nyoos nrog cov ntsev ntsev ntawm kaum tawm txhiab milligrams ib liter rau hauv dej tshiab uas ua tau raws li lub teb chaws lossis thoob ntiaj teb cov qauv dej haus, txaus siab rau cov dej xav tau ntawm cov ntug dej hiav txwv thiab cov kob. Ib txhij, nyob rau hauv cov dej khib nyiab desalination thiab siab -salinity hauv av purification, siab -cov ntaub ntawv siab tuaj yeem khaws cov calcium, magnesium, thiab sulfate ions, txhim kho cov saj thiab siv tau ntawm cov dej.
Kev kho cov dej khib nyiab hauv kev lag luam yog lwm qhov tseem ceeb ntawm daim ntawv thov rau siab - siab membranes. Rau siab - ntsev organic cov dej khib nyiab tsim los ntawm kev lag luam xws li tshuaj lom neeg, hluav taws xob, thiab metallurgy, siab - cov ntaub so ntswg muaj peev xwm ua tiav cov ntsev concentration thiab dej tshiab rov qab rau hauv xoom- tso tawm los yog ze rau - xoom- cov txheej txheem tso tawm, hloov cov dej khib nyiab rau hauv cov txheej txheem rov siv tau dej los yog ua raws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tsawg. Hauv kev kho cov dej khib nyiab pov tseg, siab - cov ntaub ntawv siab kuj tseem tuaj yeem khaws cov ammonia nitrogen, cov hlau hnyav, thiab cov organic teeb meem recalcitrant, txhim kho qhov ruaj khov ntawm cov dej ntws zoo.
Hauv kev lag luam biopharmaceutical thiab tshuaj zoo, qhov uas yuav tsum tau muaj rau kev sib cais purity yog nruj heev, siab -siab membranes ua lub luag haujlwm tseem ceeb hauv kev ua kom huv thiab hnyav rov qab. Kev sib cais ntawm cov tshuaj tua kab mob, peptides, thiab kev npaj enzyme tuaj yeem ua tiav kev sib cais ntawm cov khoom xyaw nquag thiab impurities los ntawm kev siab -siab rov qab osmosis los yog nanofiltration, ua kom cov khoom tawm los thiab zoo. Hauv kev ua kom zoo ntawm cov tshuaj suav tshuaj suav tshuaj, siab - cov pa hauv siab tuaj yeem tshem tawm cov xim loj ntawm cov xim molecular thiab colloids, txhim kho cov purity ntawm cov extract. Tsis tas li ntawd, siab - siab hnyav- cov kuab tshuaj tiv thaiv tuaj yeem ua haujlwm ruaj khov hauv cov tshuab uas muaj cov kuab tshuaj organic xws li cawv, ketones, thiab esters, ua tiav cov kuab tshuaj rov qab thiab cov khoom siv concentration, txo cov khoom pov tseg pov tseg.
Nyob rau hauv lub zog thiab cov peev txheej rov qab los, siab - cov ntaub ntawv siab yog siv nyob rau hauv oilfield tsim cov dej kho kom tshem tawm cov roj thiab ntsev kom tau raws li qhov yuav tsum tau txhaj tshuaj lossis tso tawm. Hauv kev rho tawm cov peev txheej xws li lithium thiab poov tshuaj, siab - cov ntaub so ntswg muaj peev xwm pab tau rau hauv kev sib cais thiab concentration ntawm brine los ntawm cov pas dej ntsev, txhim kho tus nqi rov qab ntawm cov ntsiab lus tseem ceeb.
Nrog rau kev nce qib hauv cov ntaub ntawv tshiab thiab cov txheej txheem tshiab, daim ntawv thov dav dav ntawm siab - siab membranes tau nthuav dav mus rau hauv cov chaw tawm tshiab xws li hluav taws xob- qib ultrapure dej npaj thiab kev kho cov kua siv los ntawm cov roj teeb hluav taws xob tshiab, ua kom pom dav dav dav thoob plaws kev lag luam thiab kev tshaj tawm, thiab nws txoj kev loj hlob ntxiv.
