Description:
Solvent extraction of contaminated soils, sludges and sediments has been successfully completed at a number ofSuperfund sites. Each commercialized process uses a unique operating system to extract organic contaminants from solids. These operating systems may be classified by the properties of the solvents each utilizes: (1) standard solvents, (2) near-critical fluids /liquified gases, and (3) critical solution temperature solvents. Pretreatment and post-treatment requirements vary depending upon the operating systems of the solvent extraction system. Future demonstrations of these technologies by the U.S. EPA`s Superfund Innovative Technology Evaluation Program will provide additional information regarding the efficacy of these processes.
