Lub lim cov nyhuv ntawm lub phaj thiab ncej lim xovxwm yog heev nyob ntawm cov khoom ntawm cov khoom siv:
* Yog tias cov khoom siv tau zoo dhau (<1μm) or in a colloidal state (such as protein solution), the filter cloth is easy to clog and the filtering efficiency is greatly reduced;
* Yog hais tias cov khoom siv yog corrosive heev (xws li muaj zog acid, corrosion-resistant cov ntaub ntawv (polyporylene) yuav tsum tau siv, tab sis cov cuab yeej siv yuav nce ntxiv.
* Yog tias cov ntaub ntawv muaj cov khoom sib txawv (xws li cov tshuaj lom organic), yuav ua rau muaj kev phom sij, lossis ua rau muaj kev nyab xeeb rau kev nyab xeeb.
Lub ntsiab
Qhov tsis zoo ntawm phaj thiab ncej lim xovxwm yog tsuas yog kev tawm suab, thiab cov khoom siv tsis txaus, nws yog ib qho tsim nyog los sib piv thiab xaiv nrog lwm lub cev qhuav dej cov khoom siv (xws li centrifuges, siv tawv lim tes) raws li cov kev txwv uas tau rub tawm (xws li cov khoom siv los ua haujlwm tshwj xeeb) .
