Fanlo^ ' Ecole Nationale Superieure en Genie des Technologies Industrielles, Laboratoire de Genie des Procedes, Section d'Etudes de I'Air *Ecole des Mines d'Ales, Laboratoire Genie de I'Environnement Industriel Abstract Experimental research is currently being conducted in the Air Study Laboratory (LEA) of the ENSGTI on the treatment of air containing volatile organic compounds (VOCs) by biofiltration technology. A pilot-scale biofilter unit was designed for this work. The experimental set-up consists of a high-quality glass column containing a natural organic filter material with a microbial strain population and nutrients. The three compounds being studied are toluene, acetone and trichlorethylene. The objective of this paper is to summarise some experimental results concerning the biofilter operation limits at various air flow and constant mass loading; the characterization of the microbi
