- Control of fouling is a critical issue to increase the competitiveness of ultraï¬ltration (UF)membranes for drinking water and wastewater treatments. Highly fouling resistant UF membranes synthesized by photo-graft copolymerization of a water soluble monomer, poly(ethylene glycol) methacrylate (PEGMA), onto a polyethersulfone UF membrane have been evaluated with respect to the adsorptive as well as the ultraï¬ltration fouling. Protein, humic substance and polysaccharide solutions were used as the model for foulants occurring in the water sources for drinking water as well as in wastewater efï¬uents. The results show that the modiï¬ed membranes exhibited a much higher fouling resistance for all foulants than the unmodiï¬ed membranes. Their combined high fouling resistance and high rejection suggests that the obtained modiï¬ed membranes are very promising as a new generation of thin-layer composite low fouling UF membranes for drinking water and wastewater treatment applications.
