Nyob rau hauv cov txheej txheem kev sib cais membrane, tubular ultrafiltration membranes, nrog rau lawv cov yam ntxwv zoo thiab zoo adaptability rau ntau yam kev khiav hauj lwm tej yam kev mob, tau dhau los ua ib tug tseem ceeb technology rau kev kho mob siab - tshem tawm cov khib nyiab, siab - viscosity, thiab yooj yim fouled feed solutions. Lawv qhov tseem ceeb yog nyob rau hauv lawv lub peev xwm los kov yeej cov kev sib tw sib cais uas cov txheej txheem nyias nyias tawm tsam nrog, thiab hauv lawv lub luag haujlwm tsis tuaj yeem hloov pauv hauv qhov siab - kev txhim kho zoo ntawm ntau lub lag luam.
Lub ntsiab tseem ceeb ntawm tubular ultrafiltration membranes yog thawj zaug hauv lawv cov kev tiv thaiv zoo heev -fouling thiab ruaj khov kev ua haujlwm muaj peev xwm. Lawv qhov dav ntws channel tsim tso cai rau cov tshuaj pub noj kom tswj tau tus nqi siab thaum lub sij hawm hla - ntws pom, zoo suppressing concentration polarization thiab particulate matter deposition ntawm daim nyias nyias. Txawm hais tias muaj cov txheej txheem nyuaj uas muaj roj, flocculants, lossis cov ntsiab lus siab, lawv tuaj yeem tswj xyuas lub voj voog ntev thiab cov flux ruaj khov. Cov yam ntxwv no ua rau txo qhov zaus ntawm kev kaw ntau zaus rau kev ntxuav thiab hloov daim nyias nyias, txhim kho kev ua haujlwm txuas ntxiv thiab kev lag luam.
Thib ob, tubular ultrafiltration daim nyias nyias muaj cov kev xav tau zoo rau kev pub noj tshuaj pretreatment, tso cai rau kev ua haujlwm ncaj qha txawm tias nyob rau hauv cov xwm txheej uas muaj kev hloov pauv loj hauv cov khib nyiab pov tseg, txo qhov nyuaj thiab tus nqi ntawm pretreatment cov kauj ruam. Nws cov qauv ua kom yooj yim rau kev ntxuav lub cev rov qab, ntxuav huab cua, thiab tshuaj tua kab mob, ua rau muaj cov kab mob sib kis tau zoo thiab kev ua haujlwm sai ntawm daim nyias nyias. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev kho dej loj, khoom noj thiab tshuaj, thiab cov txheej txheem tshuaj uas yuav tsum tau ua haujlwm tas mus li.
Nyob rau hauv daim ntawv thov, qhov tseem ceeb ntawm tubular ultrafiltration membranes nyob rau hauv lawv broad cross-kev txhawb nqa kev lag luam. Hauv kev kho dej khib nyiab thiab rov qab siv cov dej rov qab, nws tuaj yeem ua kom huv huv biochemical effluent los yog cov dej khib nyiab, khaws cov colloids, kab mob, thiab cov khib nyiab tshem tawm kom muaj kev nyab xeeb ntawm cov txheej txheem tom ntej lossis rov siv dua. Hauv kev lag luam zaub mov thiab dej haus, nws tuaj yeem qhia meej thiab mloog cov kua txiv hmab txiv ntoo, cov khoom noj siv mis, thiab cov nroj tsuag rho tawm, sib npaug kev khaws cia zoo thiab txhim kho kev muaj peev xwm. Nyob rau hauv biopharmaceutical teb, nws muaj peev xwm qhia meej fermentation broths thiab concentrate proteins, xyuas kom meej cov khoom purity thiab tawm los. Hauv kev lag luam tshuaj thiab mining, nws yog siv rau pigment thiab catalyst rov qab thiab slurry concentration, txhim kho kev siv peev txheej.
Tsis tas li ntawd, qhov siab -kub tsis kam, muaj zog acid thiab alkali tsis kam, thiab hnyav tsis kam ntawm tubular ultrafiltration membranes tso cai rau lawv hloov qee cov khoom sib cais nyob rau hauv huab cua txias, ua kom yooj yim cov txheej txheem thiab txo kev siv zog. Nws cov qauv tsim qauv kuj pab txhawb kev nthuav dav thiab kev hloov kho, ua kom cov lus teb sai sai rau cov kev xav tau ntawm cov nplai sib txawv thiab cov txheej txheem hloov pauv.
Zuag qhia tag nrho, tubular ultrafiltration membranes, nrog rau lawv cov kev sib xyaw ua ke ntawm kev muaj zog antifouling, dav siv tau yooj yim, kev saib xyuas yooj yim, thiab kev ntseeg siab, tau dhau los ua cov cuab yeej tseem ceeb rau kev nyuaj rau kev sib cais, muab cov khoom siv kev txhawb nqa rau kev tsim khoom huv si, kev siv khoom siv, thiab kev nyab xeeb ntawm dej. Lawv qhov tseem ceeb yuav tseem ceeb ntxiv nyob rau hauv cov txheej txheem ntawm ntsuab, qis- carbon, thiab siab - kev loj hlob zoo.
