Performance of photocatalytic membrane reactor with dual function of microfiltration and organics removal

A nano-structured TiO2 membrane having desired pore structure has been prepared by the anodization treatment of micro-porous tubular type pure titanium filter. The anodized nano-structured TiO2 membrane was found to act as photocatalyst and decompose N-nitrosodimethylamine (NDMA) efficiently under UV irradiation. This UV/anodized TiO2 membrane process realized the complete removal of NDMA with 20 mg L-1 concentration, indicating that this process can be a promising technology for the purification of NDMA contaminated water.This study was supported by Basic Science Research Program through National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology (2011-0013792) and partially was partially supported by the Eco-Innovation project of the Ministry of Environment
