The anti-biofouling performance of silver nanoparticles (Ag NPs) modified polyethersulfone (PES)membrane was evaluated during the concentration of fermentation broth. The Ag NPs containingmembrane did not exhibit biofouling mitigation performance during thefirstfiltration cycle, but couldhelp to recover waterflux upon physical cleaning. After threefiltration-clean cycles, the Ag NPscontaining membranes presented higher waterflux and slowerflux decline than the control membraneswithout Ag NPs. Ag NPs on the membrane surface facilitated the effective removal of cake layer. Moreover, the Ag NPs-containing membrane had no negative effects on the activities of bacteria infermentation broth.
