Hahn, W. AND H. Skovronek. TECHNOLOGY EVALUATION REPORT: BIOLOGICAL TREATMENT OF WOOD PRESERVING SITE GROUNDWATER BY BIOTROL, INC. U.S. Environmental Protection Agency, Washington, D.C., EPA/540/5-91/001 (NTIS PB92110048), 1991.
Description:
This report provides the in-depth data analysis from the SITE Program's six-week demonstration of BioTrol's Aqueous Treatment System (BATS) at the MacGillis and Gibbs Company wood treatment facility in New Brighton, Minnesota. he pilot scale (5gpm), fixed-film biological system using a pentachlorophenol-specific bacterium was evaluated at three groundwater throughput rates. perational and analytical data were carefully monitored throughout to establish a database to use in evaluating the vendor's claims for pentachlorophenol (PCP) and polynuclear aromatic hydrocarbon (PAH) removal. ased on the results of the demonstration, it was concluded that the system achieves over 95% PCP removal (vendor's claim: 9O%), probably by mineralization to carbon dioxide water and chloride ion. ecause of unexpectedly low concentrations in the groundwater, removal of PAH's could not be determined. etals (chromium, copper and arsenic) and oil did not appear to interfere with PCP removal at the levels encountered. perating costs (labor, nutrients, caustic, and utilities) were estimated at $3.49/1000 gal for the pilot-scale unit and are expected to decrease significantly on scale-up ($2.43/100 gal in a 30 gpm unit).
