Nitrogen and Phosphorus Removal from Wastewater
2014-9-22 A post-treatment process is therefore required to remove nitrogen and phosphorus from the effluent. However, because such effluents contain only small amounts of organic compounds, a carbon source must be added to remove the nitrogen. The conventional methods for post-treatment denitrification often employ methanol for the removal of nitrate .
