Resources Conservation Company B.E.S.T. (Trade Name) Solvent Extraction Technology: Application Analysis Report

摘要

The report summarizes the findings of an evaluation of the Basic Extractive Sludge Treatment (B.E.S.T.) solvent extraction technology developed by Resources Conservation Company (RCC). During the demonstration test, the B.E.S.T. system was used to treat composited sediments from two areas of the Grand Calumet River. Contaminant concentration reductions of 96 percent for total polynuclear aromatic hydrocarbons (PAHs) and greater than 99 percent for total polychlorinated biphenyls (PCBs) were achieved for Sediment A. Contaminant concentration reductions of greater than 99 percent for total PAHs and greater than 99 percent for total PCBs were achieved for Sediment B. Removal efficiencies in excess of 98 percent were realized for both sediments for oil and grease (O&G).
