Cometabolism of Monochloramine by Nitrosomonas europaea under Distribution System Conditions


This presentation was given at the AWWA Water Quality Technology Conference and Exposition Conference in Toronto, Canada on November 7, 2012 during the session on “Disinfectants: Impact and Changes in the Distribution System.” The presentation highlights the ongoing WaterRF project, “Monochloramine Cometabolism: The Missing link in Understanding Disinfectant Loss During Nitrification Episodes in Distribution Systems” (project # 4341). It focuses on occurrence of monochloramine cometabolism under drinking water condition, kinetic models to describe monochloramine cometabolism, and the potential significance of monochloramine cometabolism in practice.
