Abstract

In this work an optimum storage strategy is proposed for fresh water and waste water minimization in multipurpose batch plants. Three intermediate storage strategies considered for cost comparison. The graphical approach of representation of water composite curves and the concept of water surplus which is similar to the grand composite curve in heat pinch analysis is applied here for targeting fresh water and wastewater minimization. Analysis of results reveals that intermediate storage strategy helps in reuse of low COD wash water for further washings. This strategy reduces fresh water intake by approximately 40% for the industrial case study under consideration
