Extraktive Methods (chemical/ physical treatment)
Decontamination of Soil Material. Separation of polluted Soils.
The contaminated excavated material is being treated in a soil washing plant. The soil washing carries out a process which is made up of several individual steps (classification & grading process, mixing operations and washing procedure).
The separation of polluted soils is usually done with the help of water (other ingredients as needed) and supported by a mechanical energy input (stirring, shearing, bulging, high pressure).
