The objective of this study was to determine whether fluorescence can be used to represent the chlorine-reactive fraction of natural organic matter (NOM), and that a two-species model, with some measure of fluorescence representing the reactive NOM fraction, can be used to model chlorine decay. The study examined the chlorine and fluorescence decay of chlorinated waters and evaluated the impact of different source waters, pH, temperature, rechlorination, and treatment type; coagulation, activated carbon adsorption (GAC), ultraviolet (UV) irradiation, ozonation, and ozone / biofiltration (O3/BF). The latter four treatment processes were performed after coagulation. The treatment processes were all performed at the benchscale. The water set aside to represent raw (untreated) water is filtered with a 1-µm cartridge filter. Results for two source waters (Harwoods Mill Water Treatment Plant, Newport News, Virginia and Winchester Water Treatment Plant, Kentucky), four different treatment levels, and three different chlorine doses are included in this study. Includes 12 references, table, figures.
