The Government is all set to fix responsibility for pollution of the Yamuna.

Modern wastewater treatment systems require air in order to maintain biological activity. Often air is also needed to maintain a thoroughly mixed system. Any air introduced beyond what is needed for these two processes is considered excessive and may be eliminated to reduce power consumption.

Wastewater reclamation has become a viable alternative to supplement water supplies in water short areas. In particular, membrane treatment has played an important role in purifying the water cost effectively. Reverse osmosis (RO) membranes have been shown to significantly reduce total dissolved solids, heavy metals, organic pollutants, viruses, bacteria and other dissolved contaminants.

Ozone technology has been used for the past two decades or more. It is, however, only now that its use in wastewater treatment has been recognized. The location of ozone use in wastewater treatment determines the goal of treatment. At the same time, ozone finds use in each stage of wastewater treatment.
