AWWA WQTC71621

This powerpoint presentation begins by providing a brief overview of chlorination, and strategies to reduce disinfection byproduct (DBP) formation. Research objectives were to: investigate haloacetic acid and nitrosamineformation as a result of the interactions betweendisinfectant residual, pipe materials, and corrosioninhibitors;elucidate the kinetics of disinfectant residualdegradation and DBP formation; and,develop empirical and mechanistic models topredict haloacetic acid and nitrosamine formation. Research methodologies included: simulated distribution system (SDS) to determine the significance of influential factors; material-specific simulated distribution system (MS-SDS) for single factor experiments with the presence of pipe coupons; uniform formation conditions (UFC) to identify the roles of corrosion inhibitors and pipe materials; and, pipe loops to study the influence of biofilm and hydrodynamics. Results of kinetic studies are presented. Includes tables, figures.
