| Summary: | Water is the most common raw material in the industries.Due to the increasing water scarcity in certain countries,many industries are exposed to the fresh water risk.In order to overcome this problem,optimal water allocation network is applied in many industrial plants.In this study,a new generic mixed integer non-linear programming (MINLP) involving multiple contaminants,pH,hardness and total dissolved solid (TDS) is present to maximize the fresh water saving in the plant.All options including source of elimination,source of reduction,reuse or recycle, outsourcing and regeneration are considered in water minimization network.Four major steps,limiting water data extraction,superstructure representative,developing mathematical formulation and applying GAMS software are followed in this work.Minimum water target is then design based on the steps used to achieve the maximum freshwater saving and wastewater generation.By the end of this study, the design of water network system give higher percentage reduction of the freshwater consumption and the waste water generation. |
