SYNOPSIS T he paper describes the refinement and application of a mathematical model to investigate the hydraulic design features of a chlorine contact tank. The mathematical model study is an extension of a previous theoretical and laboratory model study, where the main objectives were to modify the flow through features of an existing chlorine contact tank, in order to reduce the effect of short circuiting and the existence of dead space zones. Flow through curves for a plug source input were obtained from the two‐dimensional depth averaged mathematical model simulations, with the predicted outflow tracer time variations being compared with the corresponding laboratory model results and field data. These comparisons were undertaken for several contact tank configurations, with encouraging agreement being obtained between the predicted and measured results for the original tank configuration. However, the agreement between both sets of results for the final tank configuration was not as good, due to the inability of the mathematical model to reproduce adequately complex three‐dimensional flow features.
