Free chlorine is widely used as a primary and secondary disinfectant for drinking water.
When disinfection byproducts (DBPs) are concerned or where the free chlorine
residual is difficult to maintain, chloramines are usually used to provide a stable
disinfection residual in distribution systems. Kinetic models for chloramines have been
developed by researchers in a bench-scale level. Chloramines are formed when free
chlorine and ammonia are mixed in a turbulent environment. Currently, experience and
rule of thumb are used in the design of mixers that are used in the chloramination
process. In this study, CFD models combing the chloramines kinetic model and the turbulent
micro-mixing model were developed and tested against tracer testing and pilot-scale testing. A
new micro-mixing model multi-fluid model (MFM) was used together with the
traditional species transportation model. Numerical simulations were compared with
experimental measurements to evaluate the model's performance. Includes 4 references, table, figures.
