Abstract:
 Two kinds of amphiphilic modifiers, polyethyleneimine-polyoxyethylene-polyoxypropylene (PEI-PEO-PPO) and polyethyleneimine-polyoxyethylene-polyoxypropylene (PEI-PPO-PEO), were designed and synthesis in order to solve the serious membrane fouling during the application of UF membrane for oily wastewater treatment. Then the antifouling PES ultrafiltration membranes were fabricated by blending modification methods. Experimental results showed that the modified PES ultrafiltration membrane possess superior anti-pollution performance for handling oily wastewater. Compared with the unmodified PES membrane, the flux decay ratio was decreased from 40.8% to 31.3%, the flux recovery ratio (simple hydraulic cleaning) was increased from 42.3% to about 99.5%. The hydrophilic PEO segments segregated onto the membrane surface and then formed a stable hydration layer near the membrane surface via the hydrogen bond. The contaminant was difficult to break the hydration layer and adsorb onto the membrane surface, thus endowing the membrane with a superior antifouling performance.
