  • Publication number: 20020027107
    Abstract: Proposed is a method for purifying and neutralizing polluted liquids, which method comprises the steps of: passing the liquid through a dispersed filtering material with particles of size 0.1-3.0 mm and additional electrode cells; before and after said passing of the liquid through the filtering material periodically regenerating a filter and applying electrical field to the filtering material in purification and/or regeneration stages wherein in the purification and neutralizing stages the filtering material and electrodes are distributed throughout the working volume in the ratio of 0.1-10.0 cm3/cm2 and compacting the same; discharging electrolysis gases in the direction not coinciding with the direction of purified liquid flow, and carrying out the regeneration stage by combined purification of both the filtering material and the electrodes in a flow of slurry formed while loosening the dispersed material in inter-electrode regions by a factor of 1.2 to 3.0.

  • Patent number: 5728660
    Abstract: A cleaning process and water-based cleaning compositions effective for the removal of radionuclides, polychlorinated biphenyls, pesticides, herbicides, and heavy metals from surfaces of all types, more especially porous surfaces, surfaces that contain irregularities and microscopic voids into which contaminants may migrate and lodge thereby creating a substrate below the surface that must also be cleaned, and particulate surfaces. The cleaning blends and processes remove contaminants from porous and irregular surfaces to such a depth below the surface and into the substrate, and to such an extent, that the cleaned surface satisfies current regulations promulgated by the EPA and NRC relating to standards for decontamination. The process also allows sealing of cleaned surfaces, if desired, with an impermeable coating of a synthetic polymeric composition in order to retard subsequent migration of any residual contaminants to the surface.
