ABSTRACT

Biofiltration is a useful process for cleaning high flow-rates of gases containing low concentrations of volatile organic compounds. An experimental program at the ICT, Prague has produced data on the performance of a pilot scale rig removing pure styrene and styrene-acetone mixtures from air. The pure component data was initially modelled using the well known Ottengraf1 equations. Often first order kinetics were found to adequately represent the concentration profiles found in the laboratory experiments.
