SITE DESCRIPTION
Treated Volume | 39 m³ of contaminated soil (pilot, 62.4 T) |
Thermal technology | Ex-Situ Treatment (ESTD) |
Main contaminant | DDT, DDD, DDE (organochlorine pesticides) |
Site challenges | Former insecticide manufacturing site (GEIGY company, active 1946-1949); pilot required to validate lab results before full-scale application |
Project Timeline | 2013 |
SOLUTION
Treatment Method |
Ex-Situ thermal desorption pilot pile (39 m³ / 62.4 T) |
Treatment program | 7 heating tubes, target temperature 250°C |
Contaminated Vapors Management | Not specified in source document |
Process control | Mobilisation: 7 days · Heating: 27 days · Sampling: 16 May 2013 · Demobilisation: 3 days |
RESULTS
✅ 39 m³ of contaminated soil treated (pilot scale). |
✅ Residual concentration reduced below the 5 ppm target (target: 5 mg/kg ms) |
✅ Pilot results validated in partnership with OGD and BURGEAP, confirming feasibility ahead of full-scale application |
