Abstract

An effluent treatment system for removing effluent gases from a gas stream including a packing having a plurality of randomly arranged elements of calcareous material. The elements may be spent shells of shellfish, especially half mussel shells and have a liquid retention portion which may form an individual liquid reservoir depending on the orientation of the element with the packing. Suitable bacteria are retained in at least some of the reservoirs. The system may be operated as a biofilter or a bioscrubber.
