Removal of DNT from Wastewaters at Radford Army Ammunition Plant
Abstract
2,4-Dinitrotoluene (DNT), a chemical used in the manufacture of single-base propellants, is a suspected carcinogen and has also been linked to heart disease by some studies. In processing propellants containing this ingredient at Radford Army Ammunition Plant (RAAP, Radford, VA) , wastewater is generated containing various concentrations of DNT. This wastewater requires abatement prior to discharge into the New River. At present, a central biological wastewater treatment plant (BWTP) is operated at RAAP for treating wastewaters. Though the Virginia State Water Control Board has not established limits on DNT discharge, monitoring is required; DNT content is discharged wastewaters must be reported semi-monthly Additionally, in the March 29, 1990 Federal Register, 2,4-DNT was listed as a constituent hazardous organic chemical. This project was tasked with the following: performance of a literature review to identify technologies available for both DNT destruction in wastewaters and DNT removal methods, based on the literature review, selection of the most promising technologies for evaluation in the laboratory to determine their removal efficiency; and bench-scale evaluations of one or more optimum technologies to quantify DNT destruction/removal efficiency and to select the best available and most cost effective technology for application at RAAP. Additionally, research was to be performed to evaluate bioaccumulation and determine if DNT was toxic to microorganisms utilized in wastewater treatment.
