V2O5-TiO2 nanoparticles were incorporated on to the ceramic ultrafiltration membrane surface and inside of pores for the enhanced oxidation of micropollutants by H2O2/UV. After V2O5 was successfully coated on the membrane through filtration-coating method, the catalytic oxidation of micropollutants was conducted on a V2O5-TiO2 catalyst in the presence of H2O2/UV. It has been found that catalytic reactions between H2O2/UV and V2O5 can improve permeate water quality as well as mitigate the membrane fouling. Consequently, a more strategic use of hybrid V2O5-TiO2 catalyst-coated ceramic UF membrane for the micropollutant removal, which requires less amount of oxidants due to catalyst, approaches to be a more economical suggestion.
