● Kev ntxuav cov dej saum npoo av.
● Rov siv cov dej khib nyiab hnyav.
● Pretreatment ntawm RO.
Cov teebmeem hauv qab no tau ua pov thawj raws li kev siv hloov kho PVDF hollow fiber ultrafiltration membrane hauv ntau hom dej:

Kev kho kom zoo yuav tsum tau teem caij thaum cov dej nyoos muaj ntau cov impurities / coarse hais los yog loj feem ntawm cov roj. Defoamer yuav tsum tau siv los tshem tawm cov foams hauv lub tank membrane thaum tsim nyog, thov siv cawv defoamer uas tsis yooj yim rau scale.
