<p>The present invention relates to an apparatus for the removal of contaminants from a gas stream by microbiological means, comprising scrubbing the gas stream with an aqueous solution into which a major fraction of the contaminants are absorbed. Subsequently, the gas with the entrained liquid is passed into contact with a microbial culture capable of decomposing the contaminants contained in the gas stream. The microbial culture is supported on a growth substrate made from mineral wool.</p> |
