Abstract

A filter plant for the exhaust air of animal farms, sewage installations or composting plants contains a filter mass of earth, compost and similar materials with a high content of microorganisms. An additional supply of oxygen, pref. fresh air, is made available to the filter. This has a much better efficiency than conventional filters, particularly for the removal of evil smelling odoriphores. The oxygen supply and the correct moisture of the filter can be adjusted to suit the conditions.
