Abstract:

Perchlorate is an oxidant widely used in propellants such as solid rocket motors, and in commercial fireworks and road flares. It has recently been introduced in new munitions formulations. An Air Force formulation pairs perchlorate with RDX, and numerous Army formulations use it in conjunction with RDX as well as other new energetic chemicals. Perchlorate treatment using anoxic processes has been applied to groundwaters. Treatment of munitions wastewater containing RDX as well as other high explosives by anaerobic bacteria is an emerging technology. This paper evaluates the effects of introducing perchlorate into the anaerobic treatment of munitions wastewater containing RDX, TNT and other nitrobodies. Anaerobic bacteria were able to treat both the perchlorate and munitions compounds commingled together in a single reactor. Acclimation times can be significant, and some consortia could not initially degrade the perchlorate.
