Abstract :The removal of contaminants from consumable waters by the traditional water treatment techniques is highly difficult. Disinfection of water alludes to the inactivation or pulverization of unsafe living pathogenic beings, which living in the water. Occurrence of disinfection by products insert ignore into journalissuearticles values(DBPs); during disinfection normally demonstrates lethal impacts on human health. Granular activated carbon insert ignore into journalissuearticles values(GAC); has the oldest history of decreasing of organic matters, but its role is reducing by time. TiO2 is used to accelerate the removal of the DBPs. TiO2 nanoparticles have good adsorption phenomena on the removal of those organic compounds at various pHs and temperatures and give good results. This study proved that TiO2 nanoparticles enhanced the efficiency of GAC to remove DBPs from water. While the elimination of trihalomethanes insert ignore into journalissuearticles values(THMs);, dichloroacetic acid insert ignore into journalissuearticles values(DCAA); and trichloroacetic acid insert ignore into journalissuearticles values(TCAA); using 0.5 g of GAC was determined as 61.7, 69.8 and 83.2% respectively, the elimination of them by 0.1 g of TiO2 nanoparticles:GAC insert ignore into journalissuearticles values(1:1); was estimated as 100, 96 and 100%, respectively.
