Abstract

A mathematical model which predicts and controls residual chlorine levels in cooling tower blowdown is developed and analyzed. The model has eight variations to allow for (a) the fraction of the recirculating water chlorinated, (b) the type of chlorine feed equipment used, and (c) the time length of the chlorine feed period. The variations to the model are useful not only in predicting residual chlorine levels in the blowdown, but also in making alterations in existing chlorination programs which minimize chlorine waste, provide more disinfecting efficiency, and reduce residual chlorine levels in the blowdown.
