Targeting for multiple resources

Abstract

The source composite curve is useful in simultaneously setting targets for the minimum freshwater requirement and minimum effluent treatment. The source composite curve also helps in reducing waste production for a variety of applications. In this paper, a methodology is developed to target multiple resources through the source composite curve in order to minimize the operating cost of the overall process. It is observed that it is not necessary to maximize the usage of the resource with the minimum unit cost. Hence, a prioritized cost for each resource is devised to select appropriate resources that minimize the operating cost subject to the availability of the resources.
