Water is one of the basic need for the survival of human beings on Earth. Nearly 70 percent of Earth’s surface is covered by water, only 2.5 percent of it is fresh. It is painful to say but it is true that only 1 percent of freshwater is easily reachable and much of it is trapped in glaciers and snowfields. We require it for daily uses like bathing, washing, cleaning and drinking and many more. Harsh reality is that water is unevenly distributed and large no. of human communities have no easy access to fresh water, to fulfil their basic needs. So we need to wisely use it and try to save every drop of it. As world’s population is increasing day by day and more industries are being setup, rate of water pollution has also increased. In this paper an attempt has been made to sum up and conclude various works on treatment of wastewater from different perspectives. Various mechanical, biological and electro-coagulation methods have been developed to treat wastewater. Every method works differently, with varying limitations and efficiency. This area still requires far more research, investment and development so that efficiency of proposed method is high.
