Abstract
A drum vent filter useful for venting hydrogen gas from transuranic wastes in order to remove particles from the gas while controlling the release of VOCs has a carbon-to-carbon filter media of increased density with a relatively large filter face and reduced thickness. In addition, a protective lid is provided over the filter element which has been substantially increased so as to enhance the diffusion of hydrogen gas through the filter element.
