ABSTRACT
Earth is the only planet, which has water in abundant and in ready to us forms. So we have to consider only his water in our discussion. About 97% of wate available on earth from the area under sea, remaining 3 % is found in continent and in atmosphere. But more than 70% of this later portionis locked in glaciers and icecaps. The main reason for water shortage is uneven distribution of rain. Many other reasons are also there. Most of the water available is being polluted. So though there is water, we cannot use it as in the same form. For using the water we have to do some chemical and physical operation on this water. Bio-filtration is one of th operations for the purification of water. But we have large part of water by desalinizing the seawater. Seawater has salination value is 35000 ppm. But according to WHO fo human consumption salinity should be 500 ppm. In desalination process actual value i brought to 500PPM.
