Flow Rate Targeting for Concentration- and Property-Based Total Water Network with Multiple Partitioning Interception Units

Multiple partitioning interception units, such as flotation, flocculation settling, ultrafiltration, reverse osmosis, etc. are placed in series in practical wastewater treatment plant for the purpose of regeneration reuse/recycle, and/or for waste treatment for final discharge. Currently, no pinch-based approach addresses the flow rate targeting problem for the water network with multiple partitioning interception units. In this paper, the generalized Improve Problem Table (IPT) is first presented to target the concentration- and property-based total water network with multiple partitioning interception units. The procedure for the generalized IPT approach is illustrated in detail by solving a revised literature example. The generalized IPT includes the deduced flow rate and mass balance equations for the water network with multiple partitioning interception units, and they are utilized to check the feasibility of the results. The Excel Goal Seek feature is applied to determine the optimal solutions, and ...
