Evaluating Centrifuges for Solid-Liquid Separation in the SRS Salt Processing Program
As a pretreatment step for the caustic side solvent extraction (CSSX) flowsheet, the incoming salt solution that contains entrained sludge is contacted with monosodium titanate (MST) to adsorb strontium and actinides. The resulting slurry is filtered to remove the sludge and MST. Testing performed by the Savannah River Technology Center (SRTC) and the University of South Carolina showed cross-flow filtration rates lower than desired for simulated salt solution containing various concentrations of MST and sludge solids (i.e., 0.02 - 0.08 gpm/ft2). Because of the low filtration rates measured during simulant and real waste testing, the authors investigated centrifugation as potential replacement for the cross-flow filters.
