Prior investigations have identified many of the mechanisms by which natural organic matter (NOM), coagulant, and particles interact in ozonated systems. This study investigated the effects of ozonation on coagulation with cationic polymer and with polymer-metal salt mixtures. Pre-ozonation decreased the concentration of NOM that reacts with polymer coagulant demand, and the rate of head loss buildup during filtration.
