Bioremediation of soils contaminated with petroleum hydrocarbons using bioslurry reactors. Final report
The Department of Defense has over 12,000 sites contaminated from military activities. This report presents data from two bench-scale and two pilot-scale studies that evaluated the suitability of the bioslurry process to bioremediate soils contaminated by petroleum hydrocarbons. Soils from two contaminated sites were studied. The first soil contained polycyclic aromatic hydrocarbons (PAHs), BTEX (benzene, toluene, ethylbenzene, and xylene) compounds, ketones, and chlorinated ethanes; the second soil contained gasoline and associated compounds. Conceptual designs and costs of bioslurry processes for field applications are also presented. Bench-scale studies were performed in 5-L batch reactors, equipped with aeration and mixing equipment. Various nutrient amendments, surfactants, and selected microbial consortia were evaluated during the bench-scale studies. Several reactors were also operated using only native microbes.
