A full scale electron irradiation unit is being tested at the Virginia Key Wastewater Treatment Plant in Miami, Florida. On-going experimentation is evaluating the use of high energy electrons for treatment of water wastewater and hazardous wastestreams at a flow of 120 gallons per minute. The electron irradiator used in this study is a 1.5 Mev Insulated Core Transformer electron accelerator. Preliminary testing has focused on secondary effluent, both chlorinated and unchlorinated, from the treatment plant in Miami, Florida. Measurements have been made to define bacterial inactivation. It has been seen that the degree of inactivation of indicator microorganisms is a function of applied dose, and approximately four logs of inactivation have been measured at a dose of approximately 600 kilorads.
