Performance studies on solar thermal systems for augmenting the desalination rate of effluents and saline water

Abstract

Water is one of the natures most important gifts to mankind It is essential to life as a person s survival depends on drinking water Our earth seems to be unique among the other known celestial bodies It has water which covers two third of its surface and constitutes 60 70 weight of the living world Actually only 1 of the world s water is usable to us About 97 is salty sea water and 2 is frozen in glaciers and polar ice caps Thus that 1 of the world s water supply is a precious commodity necessary for our survival The consumption of this small quantity of water is unfit for drinking due to pathogens and salinity and is a major health hazard world wide Huge quantities of polluted water in the form of effluents are available in industries like textile and tannery In fact these industries are facing lot of problems to dispose the effluents To overcome these problems it was planned to desalinate the industrial effluent and salt water using solar desalination technique to produce fresh water newline
