Abstract:	A study was carried out to evaluate the potential effects of co-metabolism and substrate inhibition in gas-phase biofilters treating VOC, including two model chlorinated compounds commonly found in waste emission from microelectronic industry, i.e., trichloroethylene (TCE) and dichloromethane (DCM). This research involved biofilter experiments for treatment of synthetic VOC mixtures containing DCM and methanol, as well as TCE, toluene, and acetone. DCM was removed equally well with or without methanol, indicating that neither co-metabolism nor inhibition was a significant factor in biodegradation of DCM with methanol as co-substrate. The biofilter packed with activated carbon (adsorbing medium) and inoculated with acclimatized mixed consortium achieved significantly higher DCM removal efficiency and mineralization rate than that packed with anthracite (non-adsorbing medium). Pilot-scale biofiltration study was conducted for treating emissions from a semiconductor facility contaminated with TCE, acetone, and toluene showed that that the biofilter packed with activated carbon and inoculated with acclimatized mixed cultures was capable of achieving TCE removal efficiencies of 60-80%. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).
