چکیده
|
Nitrate contamination of ground water resources has increased in asia,europe,united states,and various other parts of the world. this trend has raised concern as nitrates cause methemoglobinemia and cancer. several treatment processes can remove nitrates from water with varying degrees of efficiency,cost,and ease of operation. available technical data,experience,and economics indicate that biological denitrification is more acceptable for nitrate removal than reverse osmosis and ion exchange. this paper reviews the developments in the field of nitrate removal processes which can be effectively used for denitrifying ground water as well as industrial water. © 2012 hindawi publishing corporation.
