Bioremediation is a technology that modifies environmental conditions to encourage microorganisms to destroy or detoxify organic and inorganic contaminants in the environment. The process can be applied ex situ (in biopiles, bioreactors) or in situ (treatment of groundwater and non-saturated zone).

Since 1992, Dekonta has got a know-how and a state-of-the-art equipment to treat high concentrations of petroleum hydrocarbons in soils and groundwater successfully.

Generally, the bioremediation process duration depends on several factors:

  1. The pollution nature (TPH, PAH, BTEX);
  2. Heavy fraction content and toxicity;
  3. Type of soil and contaminant sorption;
  4. Bioavailability;
  5. Target limits / final use

Main advantages of our technology:

  • Lower costs than chemical/physical methods;
  • Contaminants are usually converted into harmless products (like carbon dioxide and water);
  • Ability to clean-up sites showing the concentration of Total Petroleum Hydrocarbons (TPH) up to 100 000 mg/kg in dry matter.
