Fouling is one of the most important problems in membrane processes. The deposition of particles and their sticking on the surface, results in the formation of layers on the surface of membrane. These layers, together with particles left inside the membrane lead to a fluid-passing resistance and as a result the output flux in the lapse of time is reduced. In this research, TiO2 particles on the surface of composite RO membrane were self-assembled and radiated by UV light. The coating of membrane surface with TiO2 particles and radiation with UV light, results in a creation of photocatalytic property with an increased hydrophilicity on the surface of membrane. The flux, through a coated and UV light irradiated membrane, has increased to a large extent in comparison with a neat membrane. In this research, the performance of photocatalytic decomposition and ultrahydrophilicity under UV irradiation, which create the self-cleaning specialty in a TiO2 coated membrane and an increase in the flux, have been studied.
