Modelling the prediction of chlorine residuals in blended desalinated and fresh surface waters

In order to secure drinking water supply for Adelaide, seawater reverse osmosis (SWRO) desalination plant (SWRO) is under construction at Port Stanvac. Desalinated water will be blended with conventionally treated surface water. The blending operation will add complexity to chemical disinfectant dosing requirements that ensure compliance to health and aesthetic guidelines and community expectations. With the aim of developing a practical model for prediction of optimum chlorine dosing of blended waters, chlorine-decay data was obtained from laboratory studies for blend ratios of desalinated water to filtered surface water. A chlorine decay model, consisting of a two component exponential decay with linear function was developed based on reactions of chlorine with 'fast' and 'slow' reacting organic compounds. The model in development requires input data comprising the initial chlorine dose and the chlorine residual at a defined time (e.g.72 hours) for the treated surface water, in order to estimate chlorine decay behaviour for any blend ratio with desalinated water
