WATER POLLUTION CONTROL

Abstract

This research dealt with the difficult question of the best treatment plant configuration in a very limited manner where flow of effluent was restricted to flow direct to a discharge point or flow to a single plant and then from the plant to a discharge point. These problems can be handled much more effectively using discrete integer variables in the formulation of the model, as such we switched to the mixed integer, continuous variable formulation. In this model we used a much more extensive and realistic supporting flow network. Quality goals are enforced by introducing the auxiliary variables. The decomposition procedure which consists of alternatively solving the relaxed sub-problems was adopted and found to that these types of regional optimization models would thus seem to offer great promise for regional water quality control.
