Description:
The Filter Flow Technology, Inc. (FFT) Coloid Polishing Filter Method (CPFM) was demonstrated at the U.S Department of Energy's (DOE) Rock Flats Plant (RFP) as part of the U.S. Environmental Protection Agency's (EPA) Superfund and Innovative Technology Evaluation (SITE) program. The CPFM system is designed to remove ionic, colloidal, and complexes heavy metals and radionuclides from water. Pollutants are removed from water predominantly via sorption or chemical complexing. The purpose of the demonstration was to evaluate the ability of the CPFM system to remove low levels of uranium from RFP groundwater. During the demonstration, average uranium and gross alpha concentrations in influent water were 46 micrograms per liter (ug/L) and 91 picoCuries per liter (pCi/L), respectively. Analytical results showed that radionuclide levels decreased by about 75 percent following treatment with the CPFM system. At maximum removal efficiency, the CPFM system was capable of achieving Colorado Water Quality Control Commission (CWQCC) standards for water to be discharged from RFP. This capsule provides information on the technology applicability, technology limitations, a technology description, process residuals, site requirements latest performance data, the technology status, and source of further information.
