Targeting and Design Procedure for Water-using Networks with Single Contaminant

Abstract

Minimizing of wastewater has become a focus of research as the reduction of wastewater discharge and water conservation has great importance. Wastewater discharge and fresh water consumption can significantly be reduced by Integration of the water system. The integration is done by reuse, regeneration reuse/recycling of waste wastewater appropriately. This work shows the development of a systematic technique which target freshwater consumption and wastewater discharge to achieve the maximum water recovery for systems involving a single contaminant. A generic linear programming model has been used based on water network superstructure to generate the maximum water recovery targets and design minimum water network .It has been used in this work water path analysis and improved source shift algorithm to evolve a preliminary water network to reduce number of interconnections by incurring a penalty on both wastewater and freshwater flow rates. This method has been tested for one problem reported in the literature. It is cleared from the illustrated problems that the proposed procedure needs much less computation compared with methods taken from other literatures.
