| Date : | Thermal desorption of 8,000 tons of PAH contaminated soil coming from twenty different projects |
DEEP GREEN's regroupment and treatment center at Sotteville-Lès-Rouen (76) treated more than 8,000 tons of polluted soils coming from different GDF sites in collaboration with many consultants like Serpol, Brézillon, Ortec GSI et Ecoterres.
Main excavation locations :
- Amiens : 3200 tons
- Aix-Les-Bains : 1700 tons
- Beaune : 1200 tons
- St Vallier : 860 tons
- Arras : 300 tons
- And Calais, Frontignan , Châteaudun...
Clean-up goals:
The soils to be treated held PAH concentration varying from 500 and 10 000 ppm. The clean-up targets were set at levels under the VDSS. All clean soils were under the clean-up target after treatment.
Equipement:
The project was done with the DRAGON 35 unit, according to the law prescriptions (of the "Arrêté Préfectoral"). The unit was equipped with continuous emissions monitoring systems.
