Abstract
The invention relates to a method for biological cleaning of a contaminated gas flow containing gaseous and/or particulate contaminants comprising the steps of contacting the contaminated gas flow counter-currently with a jet of suitable microorganism-containing scrubbing liquid in order to enhance absorption of gaseous and particulate contaminants in the scrubbing liquid; recovering the scrubbing liquid in a vessel; draining part of the scrubbing liquid from the vessel and compensating the drained part with fresh liquid. The method is carried out in a reverse jet scrubber and does not use any packing material for support to the microorganisms.
