     this study describes cleaning of a waste gas stream using bench scale biofilters (bfs) or biotrickling filters (btfs). the gas stream contained a mixture of acetone, n-butanol, methane, ethylene, and ammonia, and was diverted uniformly to six biofilters and four biotrickling filters. the biofilters were packed with either perlite (bf-p), polyurethane foam (bf-f), or a mixture of compost, wood chips, and straw (bf-c), whereas the biotrickling filters contained either perlite (btf-p) or polyurethane foam (btf-f). experimental results showed that both bfs and btfs packed with various media were able to achieve complete removal of highly soluble compounds such as acetone, n-butanol, and ammonia of which the dimensionless henry’s constants (h) are less than 0.01. methane was not removed due to its extreme insolubility (h > 30). however, the ethylene (h ≈ 9) removal efficiencies depended on trickle water flow rates, media surface areas, and ammonia gas levels.
