HEME and HEPA filter element dissolution process

PDF Version Also Available for Download.

Description

High Efficiency Mist Eliminators (HEME) and High Efficiency Particulate Airfilters (HEPA) are to be used in the Defense Waste Processing Facility (DWPF) at the Savannah River Plant to remove volatile and semi-volatile effluents from the off-gases generated during the vitrification process. When removed, these filters are likely to contain radioactive contaminants, organics, and hazardous materials, which make their disposal by normal methods impractical. Hence, an alternative disposal method is needed. The alternative disposal method evaluated in this study is dissolution of the filters with caustic and acid solutions. Dissolution converts the waste into an aqueous stream, which can be transferred … continued below

When removed, these filters are likely to contain radioactive contaminants, organics, and hazardous materials, which make their disposal by normal methods impractical. Hence, an alternative disposal method is needed. The alternative disposal method evaluated in this study is dissolution of the filters with caustic and acid solutions. Dissolution converts the waste into an aqueous stream, which can be transferred to the Tank Farm and disposed of by normal means. This process was shown to be effective on a small scale in earlier studies, but the results were not well documented and the studies were not performed on fouled filters.
