Many utilities rely on chlorine disinfection to meet primary disinfection requirements.
This article reports on a model developed to predict DBPs in the distribution system of the Massachusetts Water Resources Authority, which serves many Boston-area customers. The authors encourage utilities to investigate water quality characteristics of their own water so that equations presented in this article can be modified by coefficients appropriate for a given water system. Operators will then have a tool that will allow them to determine a chlorine dosage that will keep them safely balanced on that tightrope. Mass.
