Abstract

The application of photo-catalysis combined with membrane filtration for the oxidation of humic acid substances (HA) which is one of the major natural organic matters (NOMs) is discussed in this paper. Theoretical model shows a potential advantage of photo-catalytic filtration under low flux conditions. Cross-flow filtration is applied for HA removal using a TiO2 membrane under UV conditions. An increase of the flux through the membrane was observed by applying UV light.
