Treatment of a dynamic mixture of n-hexane and benzene in a trickle-bed air biofilter integrated with cyclic adsorption/desorption beds

摘要

One of the main challenges facing biological treatment of contaminated gas streams is the inconsistency of contaminants' concentrations in the gas feed. The microorganisms responsible of the biodegradation process are very delicate to influent concentration changes. This adds an extra constraint for the other difficulties encountered in the biodegradation process.
