Effect of natural organiz matter on monochloramine decomposition: pathway elucidation through the use of mass and redox balances

Article Abstract:

Chloride emerged as the major halogen decay product both in the presence and absence of natural organic matter (NOM) on monochloramine. Monochloramine is often used as a drinking water disinfectant for systems where free chlorine residuals are difficult to maintain or where disinfection byproduct formation is significant. Ammonia and nitrogen gas are the primary nitrogen decay products when monochloramine decomposes in the absence of NOM. When NOM is present, the product speciation changes such that little nitrogen gas production occurs.
