Abstract

The in-situ embedment approach was adopted to surface-modify polysulfone ultrafiltration membranes using TiO2 nanoparticles. The coverage ratio of nanoparticles on membranes surface was changed by varying the pH and TiO2 nanoparticle concentration in the water (coagulation) bath. The membranes were characterized and evaluated by scanning electron microscope observation, contact angle measurement and conducting anti-biofouling test using P. aeruginosa. The results show that the well-dispersed TiO2 nanoparticles in the water bath of pH 4 were successfully embedded onto the membrane surface with the coverage ratio being variable. A membrane was more hydrophilic when the TiO2 coverage ratio was higher. Compared with the unmodified membrane, the modified membrane had a similar filterability and a higher anti-biofouling ability. The anti-biofouling ability was dependent on the TiO2 coverage ratio. The best anti-biofouling performance was achieved when the coverage ratio was between 22.4% and 27.7%, for which the P. aeruginosa adhesion (after 12-hour cultivation) reduced by 90% and the biofilm thickness (after 24-hour cultivation) decreased by 70%.
