Abstract :Natural waters contain natural organic matter insert ignore into journalissuearticles values(NOM); ubiquitously as a result of the interactions between the hydrological cycle and the biosphere and geosphere. During the chlorination of raw water, chlorine reacts with natural organic matter to produce disinfection by-products insert ignore into journalissuearticles values(DBPs);, such as trihalomethanes insert ignore into journalissuearticles values(THMs); and haloacetic acids insert ignore into journalissuearticles values(HAAs);, which are believed to be harmful to human health. Among the most commonly formed DBPs are the THMs. Many countries have focused on DBPs and promulgated regulations and they have regulated THMs. Because of concerns over the health effects of these organic by-products, treatment of drinking waters contain NOM have become inevitable. Natural organic matter in drinking water treatment are removed by conventional coagulation/flocculation, actived carbon adsorption, ozonation, MIEX resin and membrane filtration.
