Beschreibung
Zusammenfassung:	The present invention relates to biotrickling filter systems and the packing material employed in such systems, as well as, methods of using same to remove odour causing compounds from waste gas streams. The packing material for the biotrickling filter system includes a plurality of expanded glass granules. When used in a biotrickling filter system, the packing material is highly efficient at removing from waste gas streams hydrogen sulfide at high concentrations in low empty bed residence times.
