Soils Washing
Soils washing is a water based ex-situ volume reduction technology for the treatment of contaminated soils.
To date, over two million tonnes of soil have been treated in HBR or Heijmans installations.
The process is a physical treatment involving the mechanical and chemical separation of contaminated soil particles from uncontaminated soil.
From a feed stream of basically granular soils, the product streams would include contaminated coarse organics, clean coarse and sand products, contaminated fine organics and contaminated silts and clays.
Water used within the system is continuously recycled as part of the process.
Contaminants treatable by soils washing include;
- Petroleum Hydrocarbons
- Cyanides
- PAH
- Organotins
- Heavy Metals
- Pesticices
- PCB
- Fibrous Asbestos
