Abstract
The recent increase in awareness of industrial ecology has inspired research in inter-plant water integration. Industrial water conservation and wastewater reduction are becoming increasingly important for sustainable water resource development in industrial parks. Water supply and pricing structures provide incentives to increase water recovery ratio. This work proposes a superstructural-based mathematical optimization method for total water networks with constrained freshwater supply. This work first explores the implications of differential price, minimum freshwater flowrate, and the number of regeneration units for different constrained water supplies. Considering minimum water-using cost as the optimization objective, the minimum freshwater flowrate and its corresponding total water network structural are determined.
