Multiperiod Planning of Water Networks in Industrial Cities
MetadataShow full item record
Freshwater is an important natural resource which is required in various processes of several industries . With rapid industrialization around the globe, there has been a steady rise in demand of freshwater. As freshwater reserves are limited, there is a need to use them efficiently. Optimization of water networks in industries is a step in the direction of efficient utilization of water and for cutting down cost. Several works have been dedicated and implemented in industries for the conservation of freshwater resources. As industries grow in size with time, their water network should evolve accordingly. Current methodologies deal only with individual period optimization and do not consider the industrial city planning horizon. This is the first attempt to present a multi-period planning approach for synthesis of integrated water network within industrial cities. The formulations presented in this paper consider the cases of direct recycle and reuse (without treatment) and regeneration and reuse(with treatment). Source-sink mapping model has been implemented in both the cases The work presents optimization based models to determine the minimum freshwater usage and lowest cost design for direct recycle and reuse and lowest cost design for regeneration and reuse.
