Synthesis of Water Utilization System Using Concentration Interval Analysis Method (I) Non-Mass-Transfer-Based Operation

摘要

A strategy for water and wastewater minimization is developed for continuous water utilization systems involving fixed flowrate (non-mass-transfer-based) operations, based on the fictitious operations that is introduced to represent the water losing and/or generating operations and a modified concentration interval analysis (MCIA) technique. This strategy is a simple, nongraphical, and noniterative procedure and is suitable for the quick yields of targets and the identification of pinch point location. Moreover, on the basis of the target method, a heuristic-based approach is also presented to generate water utilization networks, which could be demonstrated to be optimum ones. The proposed approaches are illustrated with example problems.
