Abstract

We investigated the treatment performance of conventional membrane separation, UV irradiation, UV/O3 system and UV/anodized TiO2 membrane technology for the removal of N-Nitrosodimethylamine (NDMA) from water. The RO membrane did not prove to be effective for NDMA removal. The UV/anodized TiO2 membrane process decomposed almost 100% of NDMA in the range of all NDMA concentrations. UV/A-Ti-M system was achieved the complete removal of NDMA within 20 mg l−1 of NDMA concentration, indicating that the UV/ anodized TiO2 membrane process is a promising treatment technology for treating NDMA contaminated water. With regards to by-products, DMA yield increased with an increase in initial NDMA concentration, whereas MA yield decreased.
