| Customer : | BAIL INDUSTRIE (Group ARCELOR - MITTAL) |
| Project : | Thermal desorption treatment of 2000 tons of PAH contaminated soil by means of the on-site Thermopile process |
Bail Industrie, exclusive operator for the environmental treatment of the sites of the Arcelor-Mittal Group, managed the decontamination operations of the old dump of Neuves-Maisons, formerly exploited by Usinor. Deep Green was selected for the on-site Thermopile treatment of 2000 tons highly tar-contaminated soils.
Problem to solve:
The soils to be treated held average concentrations in THP of about 70 000 ppm, in PAH of 60 000 ppm; in CN of 400 ppm.
Cleaning objective:
The decontamination levels were fixed under 40 ppm.
Deep Green Solution:
The project was realized with a THERMOPILE installation, according to the DRIRE's prescriptions. Stack tests were regularly performed. The unit was equipped with Continuous Emissions Monitoring systems.
Results:
90% of the clean soils reached the clean-up target.
