SUN 143-10. Solventless Extruded Powder N-5 General. Water Pollution Study (Denitrification).
Abstract
The biological denitrification process was studied to determine its effectiveness in removing nitrates from Sunflower Army Ammunition Plant (SAAP) wastewater. Laboratory and pilot plant studies were conducted on both batch and continuous operations. Sewage and sludge from Imhoff settling tanks were used as sources of bacteria to treat neutralized wastewaters that were high in nitrates, ranging from 100 to 230 mg/l of nitrate nitrogen. Nitrate removal ranged from 70% at low temperatures to as high as 99% at high temperatures. Bacterial denitrification was found to be a feasible and practical method to reduce the concentration of nitrates in SAAP wastewater. (Author)
