Removal of Radioactive Material From Water by Slurrying With Powdered Metal

Strontium and Calcium in Municipal Water Supplies

“…Nevertheless, the maximum removals of dissolved strontium resulting from each type of treatment indicate that alum is much less effective than when used in combination with softening agents like lime-soda ash, phosphates, or ion exchangers (compare Samples 7-9). These conclusions, based on the effects of operations routinely performed in actual water treatment plants, are in general agreement with the results of published laboratory and pilot plant studies designed to assay the value of such treatments in decontamination of waters (3)(4)(5)(6)(7)(8)(9)(10)(11)(12). The authors' observations of as high as 85 per cent dissolved-strontium removal with conventional water softening procedures, when taken together with the published pilot plant studies, indicate that it would be possible to remove more than 90 per cent in the event of serious contamination of large volumes of water.…”

Removal of Radionuclides From Water by Water Treatment Processes

“…the use of metal powders and added clay materials. Laboratory jar test studies, using various metal dusts to remove specific radioactive contaminants, were carried out by Lacy (19), and data are shown in Table 13. In general, the best results were obtained with the iron dust, with removals exceeding 90 per cent, except with fission products mixture iodine, and cesium.…”

Progress in Radioactivity Instrumentation and Testing

“…During this period the AWWA, in order to keep its members informed on the subject, has published eight papers on testing for radioactivity and treatment for the removal of radioactivity from water (1)(2)(3)(4)(5)(6)(7)(8). Of particular value were the papers pertaining to the sta-Recommendations tistics and limits of accuracy of lowlevel counting.…”
