Abstract
The 1990 Amendments to the Clean Air Act have stimulated strong interest in the use of biofiltration for the economical engineered control of Volatile Organic Compounds (VOCs) in effluent air streams. Trickle bed air biofilters (TBABs) are especially applicable for treating VOCs at high loadings. For long term, stable operation of highly loaded TBABs, removal of excess accumulated biomass is essential. Our previous research demonstrated that suitable biomass control for TBABs was achievable by backwashing. Backwashing was performed by fluidizing the pelletized biological attachment media to about a 40% bed expansion. This paper presents an evaluation made of the impact of backwashing on the performance of four such highly loaded TBABs.
