Undoubtedly, water is tasteless, colorless, and odorless. However, it is full of impurities and dangerous products and activities are making it more pollute day by day. Various suspended and dissolved inorganic and organic matters are present there, which cause different problems while disrupting the beauty of the eco system. As the availability of the water is unable to fulfill the current and future demands, it is essential to treat the waste water and repurpose the same to a great extent. Another reason to treat the water is to save the environment from the harmful effects of industrial processes.
