Title: Drying of Crystalline Silicotitanate (CST) Beds by Air Flow

Abstract

The Direct Feed Low-Activity Waste (DFLAW) process has been proposed to support early production of immobilized low-activity waste (LAW) at the Hanford Site. The tank farm contractor Washington River Protection Solutions, LLC (WRPS) is developing the Tank-Side Cesium Removal (TSCR) system to accomplish the treatment objectives. The TSCR system is being designed and built by AVANTech, Inc. for WRPS and will use a filter to remove any entrained solids in the LAW and will use columns of crystalline silicotitanate (CST) ion exchange media to remove 137Cs. A key step in preparing used columns of CST for transportation and interim storage is draining and drying of the CST beds. The purpose of this study is to document testing activities that quantify the drying of full-height beds of CST material in a laboratory column that is scaled to represent the drying process of the planned full-scale CST columns to be used in the TSCR system. The purpose also includes demonstrating that CST material within the scaled column, when dried with air injection, will pass the U.S. Environmental Protection Agency’s Paint Filter Liquids Test.
