%X Low pressure membrane technology,including microfiltration and ultrafiltration,is being applied more and more in the wastewater reclamation.However,membrane fouling,especially fouling resulted from organic materials,stays a technical obstacle.In this study,the filtration experiments were performed with cellulose acetate microfiltration membrane,under constant-flux filtration mode.Secondary effluent organic matter(EfOM for short),EfOM fractions based on hydrophilic-hydrophobic property,model protein solution(BSA),humic acid were used for microfiltration experiments.Based up on the observation by using ATR-FTIR and XPS,humic acid possesses the least fouling potential among all organics used.In terms of functional groups,ATR-FTIR suggests that more amide(1 535 cm-1),aliphatic C-H(2 860~2 970 cm-1),and hydroxyl(3 400 cm-1)on membrane surfaces after filtration of BSA,EfOM,and hydrophobic part of EfOM.Comparing TMP/V,hydrophobic-basic EfOM possesses the greatest fouling potential and humic acid possesses the least fouling potential.And UVA and EEM results suggest that hydrophobic-basic EfOM and protein contributes a lot to cellulose acetate membrane fouling.
