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 mgl 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
