RDX Biodegradation by a Methanogenic Enrichment Culture Obtained from an Explosives Manufacturing Wastewater Treatment Plant

ثبت نشده
چکیده

This study examined the biodegradation of RDX in wastewater from an industrial wastewater treatment plant at the Holston Army Ammunition Plant in Kingsport, TN. Serum bottles containing 100 ml of a basal salts medium amended with 10 percent (v/v) sludge from the anoxic filter at the plant were amended with RDX and incubated under methanogenic conditions. Biodegradation intermediates corresponding to the mono-, di-, and trinitroso-RDX were observed. A methanogenic enrichment culture, derived from the wastewater, biodegraded 25 uM RDX in less than 16 days when ethanol was supplied

Stimulating the anaerobic biodegradation of explosives by the addition of hydrogen or electron donors that produce hydrogen.

The anaerobic biodegradation of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and 2,4,6-trinitrotoluene (TNT) by a methanogenic mixed culture was investigated. Microcosms containing a basal medium and the mixed culture were amended with ethanol, propylene glycol (PG), butyrate or hydrogen gas as the electron donor and a mixture of TNT (50...

Anaerobic Biodegradation of RDX and TCE: Single- and Dual-Contaminant Batch Tests

Several sites in the United States have groundwater contaminated with mixtures of high explosives and chlorinated solvents. This research examined the ability of two microbial cultures (anaerobic sludge and a facultative enrichment culture) to biodegrade singleand dual-contaminant mixtures of trichloroethene (TCE) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) under anaerobic conditions. In ...

Characterization and Kinetic study of PAH–degrading Sphingopyxis ummariensis bacteria isolated from a petrochemical wastewater treatment plant

The expansion of a microbial bank for the degradation of polycyclic aromatic hydrocarbons (PAHs) is crucial for removal of these persistent pollutants. In this study, five gram-negative, aerobic, non-fermentative bacterial strains (III-R3, IV-P11, IV-P13, IV-R13, and V-P18) were isolated from the activated sludge of a petrochemical wastewater treatment plant using enrichment pro­ tocol based on...

Anaerobic treatment of army ammunition production wastewater containing perchlorate and RDX.

Perchlorate is an oxidizer that has been routinely used in solid rocket motors by the Department of Defense and National Aeronautics and Space Administration. Royal Demolition Explosive (RDX) is a major component of military high explosives and is used in a wide variety of munitions. Perchlorate bearing wastewater typically results from production of solid rocket motors, while RDX is transferre...

ERDC/CERL TR-08-3, Anaerobic Treatment of Wastewaters Containing Perchlorate from Munitions Handling and Production

Perchlorate, an oxidizer routinely used in solid rocket motors, is easily washed out of old motors. The washout operation, however, leads to wastewater containing perchlorate. Royal Demolition Explosive (RDX), a major component of military high explosives, is transferred to Army industrial wastewaters during assembly of new munitions and during demilitarization of old munitions. New high explos...
