One of the process objectives in waste processing is to provide Defense Waste Processing Facility (DWPF) a uniform slurry composition at 13 wt % consistently over an extended period of time, i.e., one year. In preparation of the sludge for slurrying to DWPF, several questions have arose with regard to sludge suspension and mixing of solid suspension in the bulk of the tank: How much time is required to prepare a 13 wt % slurry for DWPF How long will it take to suspend completely the sludge in any particular waste tank How is slurry weight percent related to cleaning radius The objective of this study was to answer these questions. 6 figs.
