Abstract
The 1990 Amendments to the Clean Air Act have stimulated strong interest in the use of air biofilters for the control of volatile organic compounds (VOCs) in effluent air streams. Biofilters are specially suited for the treatment of gas streams contaminated with low to moderate concentrations of VOCs. The effectiveness of three biofilter media was compared; a peat mixture, a channelized medium, and a pelletized medium. Toluene was used as the model VOC. The performance of the peat biofilter was found to be very sensitive to air temperature, and feed toluene concentration, while the channelized medium biofilter suffered from short circuiting induced by uneven biomass accumulation. Furthermore, biomass removal from this medium was not practical. The pelletized medium appeared to be the medium of choice. It provided for a resilient and effective trickle bed air biofilter (TBAB) that combined efficient treatment at high organic loads and ease of biomass control.
