Disposal of HEPA filters by fluidized bed incineration

OSTI ID:6654040
Various methods of gaseous waste immobilization have been tested at the Rocky Flats Plant over the past few years. Vitrification was selected as the most promising immobilization method for wastes collected by high efficiency particulate air filters (HEPA). Two vitrification alternatives were tested, (1) punching out the filter media, feeding it into the vitrification process, and incinerating the frame, and (2) incinerating the entire filter and vitrifying the incinerator residue. It was found that present methods of handling HEPA filters produces a waste probably unacceptable at a permanent repository. HEPA filters can be successfully incinerated using a fluidized bed incinerator. Separation of the frame from the media and incinerating only the frame is an unnecessary operation. The residue from incineration of HEPA filters can be processed into a glass acceptable under proposed repository criteria.
