Abstract

Evaluates the formation of halogenated and non-halogenated disinfection by-products (DBPs) resulting from (1) ozonation followed by chlorination/chloramination, (2) ozonation followed by coagulation and chlorination/chloramination, and (3) ozonation of prechlorinated/prechloraminated water. Based on laboratory-scale studies, presents kinetic models for the formation of DBPs from these various approaches. Reports on verification of the models at several utilities using pilot- and full-scale ozonation and chlorination/chloramination. Published in 1999.
