Conceptual framework

  • Different focus of hydrocarbon damage in both soil and groundwater, in an area bigger than 11.000 m2
  • Multitechnique treatment: combination of different decontamination techniques to achieve the objectives of subsoil environmental improvement.

Techniques

Multistage High Vacuum Extraction (MPE) System
Extraction of pure product, high vacuum aspiration of contaminants from the upper unsaturated zone, capillary fringe and lower saturated zone of the subsoil.

Air sparging
Enhance the volatilization of hydrocarbons dissolved in groundwater with the injection of air and oxygenation of groundwater.

Biostimulation
Promotes bacterial activity by injecting treated water with the addition of nutrients and oxygen releasers into the underground environment.

Hydraulic barriers
Create a depression in the water table and extract the floating and dissolved phase compound.
