Bionomic counter-current packed towers are the ideal solution to air pollution problems associated with the removal of corrosive vapors, unwanted mists, noxious and odoriferous gases. By creating a counter-current flow between contaminated gases and scrubbing liquid throughout a high surface area packed bed, rapid and uniform absorption of pollutants is achieved with maximum efficiency. Series 5000 towers are designed to accept a wide variety of packings, mist eliminators and gas scrubber liquor distribution systems. This enables the scrubbers to meet a full range of applications and gas absorption requirements.
