McClellan AFB SVE Off-Gas Characterization, Literature Review, and Technology Selection

摘要

McClellan Air Force Base (AFB) in Sacramento, California, is part of the National Environmental Technology Test Site (NETTS) program. NETTS is a joint Department of Defense (DoD) and U.S. Environmental Protection Agency (U.S. EPA) program for the evaluation and testing of environmental technologies. McClellan AFB uses soil vapor extraction (SVE) systems to remove contamination from soils. The SVE systems draw air through the pore spaces between soil particles, stripping away volatile organic compounds (VOCs) and generating a contaminated gas stream, referred to as the off-gas. The objective of the NETTS program, with respect to McClellan AFB, is to develop a treatment process to remove the VOCs from the off-gas before it is discharged into the environment. Several physical and chemical processes have been tested and demonstrated at McClellan AFB and are described in Section 2. The objective of this project is to evaluate and demonstrate a biological reactor system for treating the contaminated off-gas generated at McClellan AFB.
