Water Reuse in Industry: Necessities and Possibilities

Abstract

To begin with, lack of water, declining quality of it and environmental restrictions caused to increase requirements of reusing wastewaters extremely. By industrialization and reduction of pressure on water sources, using water in industry has adequate potential to reduce costs in saving water and treatment of wastewater. Wastewater can be recycled direct and indirect based on the type and quality. There are different ways to reuse water according to progressed technology these days. Furthermore, using intelligently and reusing water with ultimate use of missed water in environment present a growing challenge in industrial management. According to availability restrictions of fresh water sources and their protection requirement, implementation of water recycling plans in water sustainable management strategy is crucial. By progressing of industrializing in developed countries, water consumption in industry has been increased simultaneous by five principal factors. One of the methods of limiting water consumption is reuse wastewater. Reduction of water consumption by industrializing can diminish water removal from local resources. Therefore, enhancement of water availability and improvement of social relations, increasing of input water’s efficiency, lowing off wastewater discharge and their pollutant loads, decrease expenses of thermal energy and process of principal costs are the most crucial factors. Finally, reusing of wastewaters has adequate potential for decreasing costs of any project as well as wastewater treatment.
