Water sources diagram method in systems with multiple contaminants in fixed flowrate and fixed load processes

摘要

Developed to deal with water allocation problems (WAP), the Water Source Diagram (WSD) method is here extended to be used in problems involving fixed flowrate operations in multiple contaminant processes, as well as processes formulated by the source and sink point of view. Therefore the WSD becomes a complete methodology to solve WAPs without regenerating operations focusing maximum water reuse. To illustrate the performance of the proposed extension, two case studies handling hybrid systems from the pulp and paper industry are presented, including industrial data from a Brazilian pulp and paper plant. The WSD results are also compared with other author's proposals, showing good performance. (C) 2017 Elsevier Ltd. All rights reserved.
