The high energy electron beam irradiation technology is a low temperature method for destroying complex mixtures of hazardous organic chemicals in solutions containing solids. The system consists of a computer-automated, portable electron beam accelerator and a delivery system. The system requires only a mixing tank to slurry the treatable solids. The computerized control system monitors the flow rate, absorbed dose, accelerator potential, beam current, and all safety shutdown features. The absorbed dose is estimated based on the difference in the temperature of the waste stream before and after irradiation. Except for slurrying, this technology does not require pretreatment of wastes. This technology treats a variety of organic compounds, including wood treating chemicals, pesticides, insecticides, petroleum residues, and polychlorinated biphenyls (PCB) in slurried soils, sediments, and sludges. Initial studies at HVEA have shown that this technology removes greater than 99% of trichloroethane, tetrachloroethane, chloroform, bezene, toluene, and phenol in aqueous streams. HVEA has also demonstrated effective removal of 2,4,6-trinitrotoluene from soil slurries. In a recent bench-scale study, a multi-source hazardous waste leachate containing 1% dense nonaqueous phase liquid was successfully treated. In another bench-scale study, a leachate containing a light nonaqueous phase liquid contaminated with PCBs was treated to F039 standards.
