Fouling prevents adoption of membrane technologies. Increasing the hydrophilicity of a membrane’s surface reduces fouling. Many researchers have successfully enhanced membrane hydrophilicity and therefore antifouling performance by imbedding inorganic nanoparticles on membrane surfaces. However, despite these studies that demonstrate the effectiveness of this technique, no study has analyzed which nanoparticle most effectively reduces fouling. This study helps fill this research gap. Four different nanoparticles, TiO2, SiO2, ZnO, and ZrO2, were dispersed in a PES casting solution at 1 wt %, and composite membranes were prepared from this casting solution via phase inversion. The membranes’ were analyzed, and the results were compared. SiO2 most enhanced antifouling performance.
