Use Cascade Analysis to Optimize Water Network (Dept. of Chem Eng)

Abstract

The drive toward environmental sustainability and the rising costs of fresh water and effluent treatment have encouraged the process industries to find new ways to reduce fresh water and wastewater flow rates. At the same time, the development of systematic techniques for water reduction, reuse and recycling within a process plant has advanced. The introduction of water pinch analysis (WPA) as a tool for the design of optimal water networks has been one of the most significant advances in the area of water conservation over the last decade (1-13).
