  • Soil Washing - CLU-INÖversätt den här sidan

    For soil washing, contaminants sorbed onto fine soil particles are separated from bulk soil in a water-based system on the basis of particle size. The wash water may be augmented with a basic leaching agent, surfactant, or chelating agent or by adjustment of pH to help remove organics and heavy metals.

  • Contaminated soil remediation

    Contaminated soil remediation 1. Soil washing. The soil washing process separates the colloidal fraction of contaminated soil from the inert fraction: all surface soil is, in fact, made up of a fine fraction (silt or clay) and a coarser fraction (sand or gravel), as well as organic matter, water and gas. Pollutants tend to bind (chemically and/or physically) to the colloidal fraction (silt ...

    Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts and ...
