International experiences for Utilization of Solar Energy For Thermal Desalination - Research Paper ExampleTherefore, there has been a considerable interest in the use of renewable or alternative energy sources to meet the demands of the diligence (Eltawil, Zhengming, and Yuan 2009 2245), since the supply of these renewable forms is potentially interminable and the generation of energy is almost completely clean. That, and given their low cost of maintenance (Eltawil, Zhengming, and Yuan 2009 2245), such energy sources, especially the harvesting of solar energy, has been get much attention lately. The final use of solar energy is for the desalination of brackish water in order to produce and supply WHO approved drink water to areas that are almost deprived of alert water resources (Eltawil, Zhengming, and Yuan 2009 2246). Water is the fundamental need of humanity, and a fundamental requirement for the functioning of industry and society. However, the overwhelming ratio of water is in the form of seawater or other forms of brackish water it is estimated that only 3% if water is available as fresh water, and out of that, less than 1% is accessible (Eltawil, Zhengming, and Yuan 2009 2246). ... Already, over a billion of the worlds population has no access to fresh water, and the demand is likely to increase by 40% of the present amount (Eltawil, Zhengming, and Yuan 2009 2246). In light of these statistics, it has become imperative that new avenues be explored that should depict with an easy, cheap and clean method of fresh water production. To that end, the utilisation of solar energy is the most effective. This paper analyses three methods of harbouring this technology, namely Multi-effect distillation or MED, Multistage bourgeon Distillation or MSF, and Reverse Osmosis, the distribution for which is given below. Fig. 1 Distribution of renewable energy powered desalination technologies (Eltawil, Zhengming, and Yuan 2009 2248). It explores which of these m ethods is the most efficient and cost-effective. It lead make with a discussion of each of these methods, as follows, followed by a study of advantages of MED over the other methods. Multi-effect distillation, or MED, is the most common and the oldest of all the techniques employ for freshwater desalination (Bruggen 2003 7). It harnesses the concept of evaporation-condensation, in that steam obtained from brackish water by evaporation is allowed to condense at a low temperature and pressure, and the heat therefrom given off is utilised to evaporate more water from the brine (Bruggen 2003 7). The water produced upon condensation of steam is collected as non-saline fresh water the ultimate goal of the set up. It is obvious that initially some energy from an external source would be needed in order to produce steam and start the cycle the rest of the steps in the cycle are
