Abstract:

Hexahydro-1,3,5-trinitro-1,3,5-triazine RDX is the primary constituent in the explosive munitions that are produced at Holston Army Ammunition Plant HSAAP, Kingsport, TN. Part of a modernization effort for the 66-year-old plant includes the goal of zero RDX discharge to the facility industrial wastewater treatment plant. This study examines multiple technologies for removing RDX from the process waste stream at Holston Army Ammunition Plant. The treatment technologies evaluated included granular activated carbon GAC, anoxic biotreatment, zerovalent iron ZVI, alkaline hydrolysis, ultra-violet oxidation, and electrochemical decomposition. Evaluation criteria include capital and operating cost, and effectiveness in transforming RDX to nontoxic end products. Based on laboratory assessments using site water, alkaline hydrolysis and electrochemical treatment were selected for pilot scale evaluation. The RDX removal half-lives for the selected technologies were on the order of 0.25 hr with decomposition of RDX from 10,000 microgramsL to less than 20 microgramsL.
