Scaling Solid Resuspension and Sorption for the Small Column Ion Exchange (SCIX) Processing Tank

The Small Column Ion Exchange (SCIX) process is being developed to remove cesium, strontium, and actinides from Savannah River Site (SRS) Liquid Waste using an existing 1.3 million gallon waste tank (i.e., Tank 41H) to house the process.  Savannah River National Laboratory (SRNL) is conducting pilot-scale mixing tests to determine the pump requirements for suspending and resuspending Monosodium Titanate (MST), Crystalline Silicotitanate (CST), and simulated sludge.  In addition, SRNL will also be conducting pilot-scale tests to determine the mixing requirements for the strontium and actinide sorption.  As part of this task, the results from the pilot-scale tests must be scaled up to a full-scale waste tank.  This presentation describes the scaling approach.
