Design of a Wastewater Reuse Network for Electroplating Processes

摘要

Electroplating plants consume huge amounts of water daily for clenaing and rinsing. Wastewater constains a variety of hazardous or toxic pollutants that are environmentally regulated. An effective way to minimize wastewater is to design a wastewater reuse network (WWRN) so that used water can be reused to a maximum extent in the same plant. In this paper, a mathematical approach is introduced to design an optimal network, even if multip'le pollutants are contained in water streams. The approach is general, systematic and easy to use. A case study is given to demonstrate its applicability.
