Evaluation of anaerobic biological activated carbon and UV/oxidation on the destruction of 2,4-dinitrotoluene in a propellant laden wastewater
- IT Corporation, Cincinnati, OH (United States)
While many army ammunition facilities are involved in evaluating the best treatment approach to explosives in wastewaters and groundwaters, little work has been performed on wastewaters containing both explosives and propellants. This paper examines the application of anaerobic biological activated carbon using an AnBAC pilot system and UV/Oxidation using an Ultrox UV/Oxidation system in the treatment of 2,4-dinitrotoluene (2,4-DNT) in the wastewater from the single-base propellants production facility at Radford Army Ammunition Plant located in Radford, Virginia. The propellants detected in the wastewater include ethyl alcohol (ethanol) and ethyl ether. This paper provides an evaluation of the efficiencies of both AnBAC and UV/Oxidation in the destruction of 2,4-DNT given variances in ethanol and ethyl ether concentrations. The affects of retention times, oxidant combinations, oxidant dosages, and UV exposure are evaluated for optimization of the UV/Oxidation system. In the evaluation of the AnBAC system, column dimensions/retention times are evaluated together with granular activated carbon (GAC) requirements, inoculation times, buffer requirements and biomass production. A discussion of the capital and operating costs and how they are affected by variances in concentrations of ethanol, ethyl ether, and 2,4-DNT are discussed with respect to both AnBAC and UV/Oxidation.
