Cov lus nram qab no teev cov qauv ntawm ultrafiltration, microfiltration thiab rov qab osmosis txheej txheem thiab ua haujlwm ua haujlwm kom sib piv.
Kev ua thiab kev khiav haujlwm
Zoo ib yam li kev rov qab osmosis, microfiltration thiab ultrafiltration kev tsim tawm yuav tsum tau kov yeej cov teeb meem ntawm concentration polarization thiab membrane pore clogging. Feem ntau, ultrafiltration thiab microfiltration membrane qhov clogging qhov teeb meem yog loj heev, feem ntau xav tau kev siv tshuab hluav taws xob nrawm dua.
Vim li no, nyob rau hauv tus tsim ntawm microfiltration, ultrafiltration txheej txheem, ntxiv rau qhov tsim ntawm tib yam reverse osmosis txheej txheem, xyuam xim rau qhov kev xaiv ntawm membrane saum npoo tshaj tawm, kua turbulence, pretreatment thiab membrane tu thiab lwm yam, tseem xav tau tshwj xeeb mloog mus rau lub Yaug rov qab los ntawm lub cev kom zoo.
Raws li cov ultrafiltration txheej txheem membrane flux ntau ntau dua qhov rov qab osmosis, ces cov concentration polarization yog cuab kev yooj yim, nws yog ib qho yooj yim tsim ib txheej ntawm txheej txheej hauv membrane, ces daim nyias nyias tsis yuav nce nrog lub siab nce, Qhov permeability no yog hu ua cov kab mob tseem ceeb heev.
Rau ib qho kev xyuam xim ntawm ib qho kev daws teeb meem, lub siab ncav cuag ib qho muaj nqis tom qab lub fwj tshuaj flue mus txog ib qho tseem ceeb heev, yog li qhov kev khiav lag luam yuav tsum raug xaiv nyob ze ntawm qhov teeb meem tsis muaj teeb meem nyob ze ntawm kev khiav hauj lwm, lub sij hawm no lub siab feem ntau yog 0.4-0.6MPa , siab dhau Lub siab tsis tsuas yog useless thiab teeb meem.
Lub lag luam ntawm txoj kev ua haujlwm ultrafiltration feem ntau yog qhov tsis ncaj ncees lawm, uas yog, cov kua dej thiab lub qhov zis ntws sib npaug, cov khoom siv ntws cuam tshuam qhov tuab ntawm lub membrane ciam txheej, ua kom zoo dua daim ntawv membrane deg yog kev ua kom txo cov concentration ntawm polarization teebmeem, txhim kho cov kua flux, uas Thiab rov qab kho osmosis txheej txheem zoo sib xws.
Hangzhou Shuidun Technology yog tshwj xeeb ntawm kev tsim thiab kev txhim kho cov dej tsis huv kho cov khoom uas muaj qhov zoo thiab resonsable nqi, nws yog qhov khoom ntawm kev kho dua reverse osmosis dej ua haujlwm. Txais tos rau ib qho kev nug.
