This paper describes a kinetic model for nitrification in a drinking water distribution system. Using Monod kinetics, a steady state plug-flow kinetics model was developed to describe the variations of ammonia, nitrite and nitrate-N concentrations in a chloraminated distribution system. Active ammonia-oxidizing-bacteria (AOB) and nitrite-oxidizing-bacteria (NOB) biomass in the distribution system was determined using predictive equations within the model. The kinetic model used numerical analysis and was solved by C language to predict ammonia, nitrite, nitrate variation. Includes 41 references, tables, figures.
