Abstract
Authors describe a mathematical programming model for the reconfiguration of existing water networks based on the stream properties that impact the performance of the process units and the environment. The model simultaneously evaluates the repiping of the existing network through the placement/reassignment of the existing treatment units, and the addition of new treatment units while addressing environmental constraints.
In addition, it accounts for the options of process modification and increased capacity of the plant. The purpose of the optimization model is to minimize the total annualized cost of the system, which incorporates the capital investment associated with process retrofitting and the operating cost which includes the cost of fresh resources. Several case studies are presented to illustrate.
