Abstract

Identifies the extent and causes of nitrification in utilities currently using chloramines as a disinfectant. Also identifies waters prone to nitrification problems, and the operational, chemical, and microbiological parameters that lead to an occurrence. Determines the impacts of chloramine chemistry, temperature, pH, and detention time on nitrification and develops a protocol to predict a nitrification occurrence. Published in 1995.
