SOIL WASHING

          Advanced Recovery Systems, Inc (ARS) has developed a technology to treat radioactively contaminated soils and render them suitable for "free-release" as per Nuclear Regulatory Commission (NRC) Option 1 limits. The process extracts the radionuclides and reduces the overall volume of contaminated soil.

          The processing involves physical separation of clean soil by particle size and density; washing of the soil with surfactant to remove adhered contamination; and treatment using appropriate reagents to extract the radionuclides from the fines fraction.

          The back end of the process involves solvent extraction of the radionuclides from the digest liquor, raffinate impurity precipitation, and reagent regeneration.

          The unique feature of this process is that the reagents are recyclable. For organically contaminated soils, an environmentally friendly organic medium is used to extract the contaminants which are recovered by distillation. Stronger reagents are recovered by ion-exchange or evaporation.

Limitations:

          Certain contaminants may be difficult to extract if they are held in a refractive medium. In such cases, a detailed factorial study may be necessary to determine the appropriate process parameters, such as time, temperature, strength of reagents, and so forth.
