The effect of ozonation on particle behavior was investigated under a variety of conditions. Spontaneous particle coagulation (particle agglomeration without coagulant addition), lowered coagulant requirements, and formation of new particles were observed in some cases. In most of these instances, the observed changes could be induced by changing solution pH and carbonate concentration via strictly inorganic reactions; they did not require the presence of ozone. In future studies of ozonation, greater attention should be paid to changes in the inorganic composition of the water accompanying ozonation and to the possible influence of these changes on the system behavior.
