Biological Pilot Plant Study at Radford Army Ammunition Plant

Abstract

Biological pilot plant studies were conducted at Radford Army Ammunition Plant (RAAP) on wastewaters originating from the manufacturing of single-base propellants and nitroglycerine. These wastes were treated with a complete mix activated sludge system, a rotating biological disc treatment system, and an aerated waste stabilization (dispersed growth) system. Extensive studies indicated that the complete mix activated sludge system tested was unstable on a long-term basis, unless very close control was maintained over waste composition and loading rates on a continuous basis, conditions not possible to meet at RAAP. The rotating biological disc treatment system was evaluated for a period of over three months and found to be very stable and to provide excellent treatment. A short study conducted using the aerated waste stabilization (dispersed growth) system indicated this to be a highly efficient waste treatment system.
