The Role of Catalytic Ozonation Processes on the Elimination of DBPs and Their Precursors in Drinking Water Treatment

Formation of disinfection byproducts (DBPs) in drinking water treatment (DWT) as a result pathogen removal has always been an issue special attention the preparation safe water. DBPs are formed by action oxidant-disinfectant chemicals, mainly chlorine derivatives (chlorine, hypochlorous acid, chloramines, etc.), that react with natural organic matter (NOM), humic substances. usually refractory to oxidation, due presence halogen compounds so advanced oxidation processes (AOPs) recommended option deal their removal. In this work, application catalytic ozonation (with and without simultaneous radiation), moderately recent AOPs, for substances also called precursors, themselves is reviewed. First, short history about use disinfectants DWT, formation discovery alternative oxidants used presented. Then, sections dedicated conventional AOPs applied remove precursors finalize description principal research achievements found literature processes. sense, aspects such operating conditions, reactors used, radiation sources case, kinetics mechanisms
