TiO2, a hydrophilic and ultraviolet (UV) light-active photocatalyst, was applied to prepare poly(vinylidene fluoride) (PVDF)/ TiO2 mixed matrix hollow fiber membranes (HFMs) by the phase inversion method. The membranes were characterized by scanning electron microscopy (SEM), attenuated total reflection Fourier transform infrared (ATR FT-IR) spectroscopy, contact angle measurement and UV-Vis absorbance. The membranes' performances for treating surface water were evaluated based on the water flux, humic acid (HA) rejection and total organic carbon (TOC) rejection in surface water. The results showed the hydrophilicity as well as water flux of the mixed matrix membranes was significantly improved under UV light irradiation when compared to original PVDF membranes. The as-prepared PVDF/ TiO2 mixed matrix membranes rejected over 40% of humic acid and 20% of TOC in a surface water sample, which were comparable to conventional PVDF membranes, but had much better anti-fouling properties.
