LAWRENCEVILLE, N.J. and RANCHO CORDOVA, Calif., June 21, 2002 -- The California Department of Health Services (DHS) recently approved the use of fluidized bed reactors (FBRs) for removing perchlorate from public drinking water supplies.
The FBR offers a highly cost effective means to remove perchlorate to below detectable levels with destruction rather than concentration of the perchlorate.
The DHS based its decision on research findings from an extensive treatability study by GenCorp at its Aerojet Facility in Rancho Cordova, Calif. An independent expert panel thoroughly reviewed and commented on the results for the DHS before the approval was issued. Aerojet has had four Envirogen FBR systems in operation at the Rancho Cordova site since 1998.
Naturally occurring microorganisms within the FBR system destroy perchlorate molecules within a matter of minutes while attached to a hydraulically fluidized bed of sand or granular activated carbon media. Both the EPA and the American Water Works Association Research Foundation (AWWARF) have recognized the FBR as one of the most economically feasible technologies for biochemically treating perchlorate-contaminated waters.
