Ultrafiltration (microfiltration) thiab microfiltration (microfiltration) kuj yog qhov sib txawv xws li kev siv zog ntawm txoj kev sib cais, feem ntau yog siv sib cais, kuj siv tau rau kev sib cais, xws li cov kab mob cua thiab cov khoom raug tshem tawm.
Lub membrane siv rau ultrafiltration yog ib daim duab asymmetric nrog nruab nrab pore loj txog li 10 txog 200 A, thiab muaj peev xwm tuav cov macromolecules thiab colloidal tiam uas muaj ib lub cev loj ntawm 500 lossis ntau tshaj. Cov kev khiav hauj lwm yog 0.1 mus 0.5 MPa.
Cov khoom siv cov kua qaub raws li qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, uas qhov hnyav los ntawm daim nyias nyias nyob ntawm micropores ntws mus rau sab tsawg ntawm daim nyias nyias rau cov kua, cov tshuaj macromolecules los yog colloidal ib yam dab tsi, tuaj yeem tsis dhau ntawm daim nyias nyias,
Thiaj li paub lub sib cais ntawm cov tshuaj macromolecular thiab colloidal thiab cov kuab tshuaj nyob rau hauv cov ntaub qhwv cov kua. Txoj cai tuav ntawm lub ultrafiltration membrane rau cov khoom tshuaj macromolecular yog qhov kev ntsuam xyuas cov nyhuv, thiab cov nyhuv ntawm cov kev cuam tshuam kev cuam tshuam yog tsuas yog nyob rau ntawm qhov pore loj thiab cov duab ntawm lub npo npog txheej txheem ntawm daim nyias nyias.
Ntxiv rau sieving, daim duab membrane, cov adsorption nyob rau hauv lub plhaub taum thiab qhov tuav ntawm cov khoom nyob hauv daim nyias nyias kuj tseem cia cov macromolecules raug daig. Xyaum tau ua pov thawj tias, qee zaum, lub cev thiab tshuaj cov khoom ntawm daim nyias nyias nyob ntawm ultrafiltration kev sib cais muaj feem tseem ceeb, vim tias kev kho ultrafiltration ntawm cov kua tshuaj macromolecular, cov tshuaj osmotic tov rau qhov txheej txheem ntawm kev cuam tshuam. Nyob rau hauv qhov kev nkag siab, nws zoo ib yam li rov qab osmosis.
ntxiv nrog rau ntxuav nrog dej sov, tab sis kuj tseem niaj hnub siv cawv tu vaj tu tsev; Kev kho membrane ntawm cov kav dej hauv tsev feem ntau siv tshuaj sodium hypochlorite. Yog tias koj muaj cov ntaub ntawv npaj ua tiav, cov mis mos thiab tu vaj tu tsev yog txiav txim siab los ntawm kev sim.
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.
