Application

There are many contaminated sites all over the world and especially in industrialized countries. There is a constant demand for cost effective remediation solutions. Existing ozone technologies often have operational and safety issues and call for high-voltage-equipment as well as increase the flammability of many materials.

Our Innovation

This technology is a unique and efficient methodology for in situ chemical remediation of contaminated soils by a unique superoxide reagent in the gas phase.

Advantages

  • Efficient permeation capacity of the reactive material
  • Minimal quantity of reagents needed and rapid reaction rates.  
  • Gas phase oxidant for buried/contaminated soil/land
  • No need for high voltage equipment
  • Low cost inputs

Technology

The proposed novel technology is an efficient process for decontamination of soil, particularly oil contaminated soil.

  • This reagent is inflammable and there is no need of high-voltage-equipment.
  • Concluded a conversion of 20% of the oil after very short reaction time with low quantities of materials consumed.

Opportunity

Superoxide production in a gas phase and its application is efficient and swift. The proposed process is superior, safer and environmentally friendly in comparison with the standard gas ISCO technology (ozone) for soil purification. There is a great economic potential of this new approach.
