Reverse osmosis, on a pilot-plant scale, was successful in removing large percentages of actinide isotopes from low-level aqueous streams. The relative effectiveness of three membrane types, 0, 50 and 97% salt rejection, in actinide removal was explored. The 97% salt rejection membrane was the most effective, generally removing in excess of 98% of the actinides. A main-effects-design experiment was performed to assess which of seven variables had a significant effect on the adsorption of cesium-137 by three strongly acidic, cationic ion exchange resins. Sodium, potassium, calcium, and cesium-133 concentrations were found to significantly affect the adsorption of two of the resins, and calcium, potassium, and cesium-137 concentrations significantly affected the third resin.
