Field Demonstration For Bioremediation Treatment Final Repon Technology Demonstration of Soil Vaper Extraction Off-Gas at McClellan Air Force Base
Abstract
McClellan Air Force Base (AFB) is a National Test Location designated through the Strategic Environmental Research and Development Program (SERDP), and was selected as the candidate test site for a demonstration of soil vapor extraction (SVE) off-gas treatment technology. A two-stage reactor system was employed for the treatment of the off-gas. The biological treatment was conducted at Operable Unit (OU) D Site S, located approximately 400 ft southwest of Building 1093. The SVE system at this area normally operates at a nominal volumetric flowrate of approximately 500 to 600 standard cubic feet per minute (scfm). The contaminated air stream from the SVE system that was fed to the reactor system operated at a flowrate of 5 to 10 scfm. The demonstration of this reactor system started with the mobilization of field equipment and personnel in November 1997. The two-stage reactor system consisted of a fixed-film biofilter followed by a completely mixed (by continuous stirring), suspended-growth biological reactor. This reactor configuration was based on a review of the literature, on characterization of the off-gas from the SVE system being operated at McClellan AFB, and on the results of the laboratory study recently conducted by Battelle and Envirogen for this study (Battelle and Envirogen, 1997c). The demonstration was run for approximately 18 weeks. This final demobilization and decommissioning of the pilot-scale reactor unit was completed on April 30, 1998.
