Title: Hepa filter dissolution process

Full Record
Other Related Research

Abstract

A process for dissolution of spent high efficiency particulate air (HEPA) filters and then combining the complexed filter solution with other radioactive wastes prior to calcining the mixed and blended waste feed. The process is an alternate to a prior method of acid leaching the spent filters which is an inefficient method of treating spent HEPA filters for disposal.

Method of treating contaminated HEPA filter media in pulp process

Patent Hu, Jian S.; Argyle, Mark D.; Demmer, Ricky L.; ...

A method for reducing contamination of HEPA filters with radioactive and/or hazardous materials is described. The method includes pre-processing of the filter for removing loose particles. Next, the filter medium is removed from the housing, and the housing is decontaminated. Finally, the filter medium is processed as pulp for removing contaminated particles by physical and/or chemical methods, including gravity, flotation, and dissolution of the particles. The decontaminated filter medium is then disposed of as non-RCRA waste; the particles are collected, stabilized, and disposed of according to well known methods of handling such materials; and the liquid medium in which themore » pulp was processed is recycled. « less

Method and apparatus for the clean replacement of contaminated HEPA filters

Patent Wiedmeyer, Stanley G.; Frigo, Arthur A.; Preuss, Daniel; ...

A method and apparatus are provided for the replacement of contaminated HEPA filters without contamination of the surrounding environment. A filter housing is generally cylindrical and defines a filter receiving cavity. The filter housing having a filter receiving end and a filter removing end. An active HEPA filter is received within the filter housing cavity and is located near the filter removing end. A backup HEPA filter is received within the filter housing cavity and is located near the filter receiving end. A change-out bag is received within the filter housing cavity and is located adjacent to the filter removingmore » « less
