Description:
This treatability study report presents the results of laboratory and field tests on the effectiveness of a new decontamination process for soils containing 2,4-D/2,4,5-T and traces of dioxin. The process employs three operations, thermal desorption, condensation and absorption of contaminants into a solvent and photo decomposition. Bench-scale tests were conducted to establish the relationships between time and temperature and treatment efficiency. A pilot-scale (100 Ibs/hr) system evaluation was conducted at two sites to evaluate system performance and develop scale-up information.
