ABSTRACT

Water shortages and unreliable water quality are considered major obstacles to achieve sustainable development and improvement in the quality of life. The water demand in the country is increasing fast due to progressive increase in the demand of water for irrigation, rapid industrialization, population growth and improving life standards. Water reuse is already an important element in water resource planning. Use of highly treated wastewater effluent is receiving more attention as a reliable water resource. For local authorities, supplying fresh water to everyone has become a key environmental and economic issue. Evaporation, or distillation, is the oldest form of treatment capable of removing soluble contaminates from water or other solvents. Desalination is the process where high TDS water is heated to produce water vapor that is then condensed to form fresh water. At present desalination is the most reliable and efficient method to treat the high TDS water. The water obtained after the process of desalination can further be used in any of the industrial processes that require mainly fresh water for their various manufacturing processes. THE RESULT shows that the presence of TVR plays a major role in increasing the total quantity of the distillate produced. It was noticed from the trials taken that the increase in the TVR pressure resulted in: the increase in condensate generation, decrease in the steam consumpion, decrease in the costing of the steam, increase in the efficiency of the system, increase in the Gain Output Ratio, Performance Ratio.
