Alternative ultrafiltration membrane testing for the SRS baseline process

An alternative state-of-the-art filtration technology implemented to facilitate the strontium and actinide removal process in a cost effective way was discussed. The investigation was performed in two phases where the first phase of testing evaluated the consistency or variability of flux through different membranes and the second phase of testing evaluated the achievable permeate flux and clarity. Small particles present in solution were unable to penetrate the ceramic layer producing surface filtration where the filter cake acted as then filter medium. Turbidity data indicated that permeate from the alternative membranes provided reduced or equivalent turbidity measurements when compared to the baseline 0.1 micron Moot membrane.
