ABSTRACT
High Voltage Electron Beam Technology

Innovative Technology Evaluation Report
EPA 540/R-96/504
August 1997
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.
