| Location : | Polígono Industrial - Aviles - Asturias |
| Project : | Thermal desorption
of 22,000 tons of PAH contaminated soil by means of mobile thermal desorption. |
| Duration : | December 2002 to March 2003 |
| Budget : | 500,000 - 1,000,000 € |
Problem to solve:
The clean-up site was formerly used by Aceralia (Steel plant) in Avilčs and the soil to treat came from the various locations within the steel factory that generated contaminated soil. The clean-up was funded by the Infoinvest (Spanish Governmental agency in charge of industrial redevelopment of contaminated sites).
The soil was already excavated by the client. Deep Green has contracted the sieving and the thermal desorption part of the contract for the PAH contaminated soil.The soil to treat had PAH concentrations varying from 500ppm up to 23,000 ppm.
Cleaning objective:
TPH content was moderate at an average of 4,000 ppm. Clean-up levels were set at 20 ppm total PAH and 50 ppm TPH. All clean-up standards for clean soil were met.
Deep Green solution:
The project started with a DRAGON 35 unit. Stack tests were successfully performed on the unit. The unit was equipped with continuous emissions monitoring.
