SITE Technology Capsule: Terra-Kleen Solvent Extraction Technology

摘要

The document describes the Superfund Innovative Technology Evaluation (SITE)Demonstration of Terra-Kleen Response Group's mobile solvent extraction process. Three individual studies were conducted. These were: (1) Treatability studies conducted on polychlorinated biphenyl (PCB) contaminated soil obtained from three individual sites; (2) A pilot scale evaluation of the process treating five, one-ton batches of PCB contaminated soil from a single site; (3) Analytical results from full scale processing of pesticide contaminated soil. Results show that the process effectively removes contaminants of concern. Removal efficiencies were consistently greater than 98% for the pilot scale evaluation. The effectiveness of the process in removing semi-volatile organic contaminants from a given soil varied.
