Performance tests were conducted to determine the capability of granular activated carbon GAC to adequately treat pink water munitions wastewater from Army ammunition plants AAPs. Comparative isotherm tests were conducted with five GACs to recommend an optimized grade for pink water treatment and to study temperature and compositional effects. Target effluent criteria of 0.04 mgL for trinitrotoluene TNT, 0.03 mgL for cyclotrimethylenetrinitramine RDX or cyclotetramethylenetetranitramine HMX, and 0.0007 mgL fo9r 2,4-dinitrotoluene 2,4-DNT were achieved in the isotherm tests. Pilot scale multiple column tests were conducted at Iowa AAP to determine GAC capabilities under typical operating conditions. The effluent criteria were generally met for RDX, HMX, and 2,4-DNT but not for TNT.
