METHOD AND APPARATUS FOR TREATMENT OF GASES

摘要

A method and apparatus for the treatment of contaminated gas which comprises placing a biofilter material (28) into a vessel (10) which is arranged to be sealed. A compressor (14) and valve (16) are provided for feeding pressurised contaminated gas into the vessel (10). A valve (20) is provided for releasing treated gas from the vessel (10). The use of pressurised contaminated gas increases the pressure in the vessel (10) which ensures a substantially even distribution of gas in the vessel (10) and the biofilter material (28). The treatment reduces the level of contaminants in the gas.
