Crossflow Filtration of LAWPS Simulants
- Pacific Northwest National Lab. (PNNL), Richland, WA (United States)
The Low-Activity Waste Pretreatment System (LAWPS) will employ crossflow filtration (CFF) to separate solids from radioactive wastes. Design verification of CFF unit operations will involve engineering-scale demonstrations of the efficacy of liquid-solid separations with low-activity waste (LAW) simulants. Before execution of integrated engineering-scale verification tests, the LAW simulants developed to support design verification activities are to be evaluated in a laboratory-scale CFF apparatus to demonstrate simulant suitability, to help refine engineering-scale filtration and filter cleaning strategies prior to implementation, and to identify any anomalous filtration behaviors that could impact the conduct-of-operations at the engineering-scale test facility. This report provides the bench-scale test results for the four LAWPS simulants developed to support integrated testing and of the eight fouling simulants selected to evaluate the sustainability of LAWPS filtration and the effectiveness of LAWPS flux recovery technologies.
