Abstract:

This document provides a performance and cost analysis for an aerobic biofiltration treatment system used to treat extracted petroleum hydrocarbon vapor from contaminated, unsaturated vadose zone soils. The BiocubeTM Aerobic Biofiltration System manufactured by EGGs Rotron Division in Saugerties, New York was evaluated by Parsons Engineering Science, Inc. Parsons ES at the Patrick Air Force Base AFB, Florida, Base Exchange BX Service Station from 15 January through 26 February 1994. The system was evaluated in conjunction with an ongoing bioventing pilot test directed and funded by the Air Force Center for Environmental Excellence AFCEE, Technology Transfer Division ERT. The purpose of this test was to independently measure both the performance and the cost effectiveness of the BiocubeTM system. A pilot test work plan was developed for testing and evaluating the EGG BiocubeTM Aerobic Biofiltration System at Patrick AFB. The primary objectives of the evaluation were 1 To determine the effectiveness of the BiocubeTM system at reducing concentrations of volatile organic compounds VOCs in vapors extracted from the soil prior to release of the vapors into the atmosphere 2 Determine the reliability and maintainability of the BiocubeTM system and 3 Estimate the cost of installing and operating the BiocubeTM. Secondary objectives included improving the sampling, analysis, and air flow adjustment process to achieve a more rapid BiocubeTM system stabilization and achieving removal rates of volatile hydrocarbons of greater than 90 percent for benzene, toluene, ethylbenzene, and xylenes BTEX and 75 percent for total volatile hydrocarbons TVH at a process-stream vapor flow rate of 50 standard cubic feet per minute scfm or less. The evaluation of this system at the Patrick AFB BX service station site was disappointing.
