Depollution

Whether dealing with a disaster or ceasing activity at a site, companies specializing in depollution use both technical and human means to carry out these extremely technical operations:

  • Soil treatment: screening, dehydration, stabilization, thermal desorption, venting, soil flushing
  • Groundwater treatment: pumping, skimming, filtration, stripping, aeration, and on-site biodegradation
  • Deconstruction: cleaning, drainage, suction, and dismantling industrial equipment

These operations generate by-products that must be eliminated. We assist depollution professionals to control the effluents they encounter.

We also operate directly at sites undergoing depollution (on-site), as well as at treatment platforms for polluted lands.

Fine screening and sieving to collect debris and solid residue

Physical and chemical treatment using flotation separation to capture hydrocarbons
Activated carbon adsorption to retain organic molecules (phenols, PAH, TOC)
Biological treatment to eliminate dissolved pollutants (alcohols, polar pollutants)
