Brackish Water Desalination Using Solar Desalination Pannel
Journal Title: Current Investigations in Agriculture and Current Research - Year 2018, Vol 3, Issue 1
Abstract
The origin and continuation of mankind is based on water. Water is one of the most abundant resources on earth, covering three-fourths of the planet’s surface. Water is one of the earth’s most abundant resources, covering about three-quarters of the planet’s surface. The reason for this apparent contradiction is, of course, that - 97.5% of the earth’s water is salt water in the oceans and only 2.5% is fresh water in ground water, lakes and rivers and this supplies most human and animal needs. It would be feasible to address the water-shortage problem with seawater desalination; however, the separation of salts from seawater requires large amounts of energy which, when produced from fossil fuels, can cause harm to the environment. Therefore, there is a need to employ environmentally-friendly energy sources in order to desalinate seawater. Solar distillation systems are increasingly attractive in the areas suffering from shortages of fresh water but where solar energy is plentiful and where operational and maintenance costs are lowWater is essential for life. Many countries around the world, especially developing countries and countries in the Middle East region, suffer from a shortage of fresh water. The United Nations (UN) Environment Programme stated that one-third of the world’s population lives in countries with insufficient freshwater to support the population [1]. Consequently, drinking water of acceptable quality has become a scarce commodity. The total global water reserves are _1.4 billion km3, of which around 97.5% is in the oceans and the remaining 2.5% is fresh water present in the atmosphere, ice, mountains and ground water. Of the total, only _0.014% is directly available for human beings and other organisms [2]. Thus, tremendous efforts are now required to make available new water resources in order to reduce the water deficit in countries which have shortages [3]. According to World Health Organization (WHO) guidelines, the permissible limit of salinity in drinking water is 500ppm and for special cases up to 1000ppm [4].
