Abstract: A pleatable high efficiency non-woven, gas filtration media is provided. The media has an electrically charged air laid fibrous layer with a thickness between about 2 and about 35 mils, and a wet laid fibrous layer having a thickness of between about 5 and about 35 mils. The combined layers have, (a) a thickness of between about 10 and about 50 mils, (b) a stiffness of between about 200 and about 3500 mgs, (c) a Frazier of between about 10 and about 400 CFM, and (d) an &agr; of at least 15.

Abstract: A process for removing organic compounds from a nuclear waste slurry comprising reacting a mixture of radioactive waste precipitate slurry and an acid in the presence of a catalytically effective amount of a copper (II) catalyst whereby the organic compounds in the precipitate slurry are hydrolyzed to form volatile organic compounds which are separated from the reacting mixture. The resulting waste slurry, containing less than 10 percent of the orginal organic compounds, is subsequently blended with high level radioactive sludge and transferred to a virtrification facility for processing into borosilicate glass for long-term storage.
