Dab tsi yog Txoj Cai Ntawm Tangential Flow Filtration?

Tangential flow filtration yog hais txog daim ntawv pom nyob rau hauv uas cov kua ntws cov kev taw qhia yog perpendicular mus rau qhov pom kev. Cov tshuaj ua kua tuag lub kaum sab xis yog feem ntau microporous pom (MF, microfiltration), suav nrog daim ntawv pom siv rau kev ua kom tsis muaj menyuam. Cov kev taw qhia ntws ntawm cov kua yog tib yam li cov filtration. Nrog rau cov txheej txheem pom, lub thickness ntawm ncuav mog qab zib txheej los yog gel txheej ntawm daim nyias nyias maj mam nce thiab tus nqi ntws maj mam txo. Thaum lub lim nruab nrab yog ultrafiltration membrane los yog microfiltration membrane nrog me me pore loj, cov khoom muaj nyob rau hauv pub kua yog siab. Txoj kev tuag kawg pom yog saws, thiab tus nqi ntws poob sai heev. Yog li ntawd, tuag ces kaum pom tau tsuas yog ib qho me me ntawm cov kua pub. Rau qhov loj-scale kua-kua pom, tangential flow filtration yog yuav tsum tau. Cov kua dej yuav ua rau lub zog shear rau saum npoo ntawm cov lim xov xwm, yog li txo qhov sib xyaw ntawm cov ncuav mog qab zib los yog gel txheej thiab ua kom ruaj khov pom tus nqi. Yog li, tangential flow filtration yog dav siv nyob rau hauv ultrafiltration (UF) thiab ib nrab microfiltration (MF) txheej txheem.
