    Abstract

    This article describes a kinetic model for nitrification in a drinking water distribution system. Monod kinetics were used to develop a steady-state plug-flow kinetics model to describe the variations of ammonia, nitrite, and nitrate-N concentrations in a chloraminated distribution system. Active ammonia-oxidizing bacterial and nitrite-oxidizing bacterial biomasses in the distribution system were determined using predictive equations within the model. The kinetic model used numerical analysis and was solved to predict ammonia, nitrite, and nitrate using C programming language for computers, which is similar to FORTRAN but simpler to use.
