Soil Treatment

Augean operates the Country’s largest soil treatment centres at Port Clarence Waste Recovery Park and at East Northants Resource Management Facility.

Contaminated soils are cleansed to remove a wide range of contaminants through the use of the most advanced treatment technologies including physico-chemical and bioremediation techniques.  Clean material is recovered and recycled and pollutants analysed and disposed of safely.  Services include:

Environmental Benefits

  • The soil treatment centres can tackle a broad range of contaminants.
  • Bioremediation gives a potential 100% recovery of soils, while soil washing gives 80% recovery of sand and gravel.
  • Soil treatment is made available for sites where on-site treatment is not a viable option, thereby promoting the clean up of contaminated land.
  • Soil treatment can also be used as a pre-treatment to reduce contamination to acceptable levels before landfilling

 

Soil Washing The washing of soil with water to remove contaminants and recover sand, gravel and soil forming materials. The soil washing plant removes heavy metals from contaminated soils, silts and sludges through a physicochemical treatment process. Bulk soils are separated into coarse aggregates, sand and silt size fractions and then washed to remove surface contamination. 80 per cent of the output is clean aggregate or sand suitable for re-use.  
 
Cement Stabilisation

Mixing cement with waste that cannot be recovered to bind the contaminants by adding fly ash, cement and water to certain waste materials, a chemical reaction occurs that binds heavy metals. The resulting granular product is less likely to produce leachate than the original waste material and is suitable for disposal in landfill.

Bioremediation Composting of soil to remove organic contaminants and recover the soil in a controlled environment, specific bacteria are added to soils contaminated with organic compounds (hydrocarbons). The degradation of petroleum type materials is promoted through the circulation of air and by controlling the levels of moisture.
