A number of Army Ammunition Plants AAPs generate wastewater contaminated with 2,4,6-trinitrotoluene TNT, hexahydro-1,3,5-trinitro-1,3,5-triazine RDX, and tetramethylenetetranitramine HMX from loading, assembly, and packing of munitions, as well as washout or demilitarization operations. These wastewater streams are commonly referred to as pinkwater due to the characteristic color of the water. The current state-of-the-art for treatment of pinkwater is adsorption onto granular activated carbon GAC. The use of GAC adsorption is both costly and generates a by-product spent GAC, which is a hazardous waste. The goals of applying biological treatment using the Anaerobic GAC-fluidized bed reactor GACFBR were to reduce operating costs and eliminate the generation of the hazardous waste by-product. The objectives of the project were to evaluate the ability of Anaerobic GAC-FBR to treat pinkwater over a year s period, and determine the economics of treatment compared to adsorption using GAC. The GAC-FBR demonstration unit was manufactured by EFX1 specifically for this work. The system was tested hydraulically and electrically at EFX and then transported to McAlester Army Ammunition Plant McAAP for the demonstration. EFX personnel assisted in the installation and commissioning of the system at McAAP. EFX then trained McAAP personnel on normal monitoring, sampling and Operations and Maintenance OM activities required, and provided continued technical and analytical support throughout the duration of the demonstration.
