Abstract : A bench-scale study for the treatment of munitions wastewater was conducted in a semicontinuous activated sludge treatment system over a period of 30 months. This work effort addressed the suitability of such systems for the treatment of munitions wastewaters, system performance, system removal capabilities, and the determination of kinetic constants. The system proved to be extremely stable and easy to operate. Organic removals reached almost 100% biodegradable COD removal and were consistently in excess of 95%. Complete nitrification and denitrification were consistently achieved. Solids separation and sludge settleability were excellent. Partial removals of RDX, HMX, TAX, and SEX were achieved. DMN was neither formed nor removed during the operation of the system. TNT removal was complete, and despite intensive efforts, no metabolites or degradation products of TNT were found in either the effluent or sludge.
