Description:
Drinking water distribution systems with ammonia present from either naturally occurring ammonia or ammonia addition during chloramination are at risk for nitrification. Nitrification in drinking water distribution systems is undesirable and may result in water quality degradation and subsequent non-compliance with existing regulations. Therefore, nitrification control is necessary to maintain water quality in drinking water systems when free ammonia is present. The fundamental processes affecting nitrification occurrence in distribution systems are discussed: (1) chloramine chemistry, (2) nitrifier growth kinetics, and (3) monochloramine inactivation kinetics along with a summary of nitrification monitoring and responses typically implemented at drinking water utilities.
