Distributed wastewater treatment network design with detailed models of processes

Abstract This paper addresses design of wastewater treatment network by a sequential approach with mathematical models of treatment processes. This is a method applying insight based techniques in first stage, namely water pinch analysis and wastewater degradation concept, followed by mathematical programming. The design approach can be used for synthesis and also for retrofit of wastewater treatment networks. Application of mathematical models of treatment processes allows taking into account relation between removal ratio of treatment process and treatment flow rate as well as concentration of certain contaminants. The approach was used for solving problems of designing and retrofitting wastewater treatment systems of various industrial plants.
