A seminar was held simultaneously with a demonstration of a full-scale system for removing radiostrontium from fluid milk at the Producers Creamery Company, Lebanon, Mo. The removal rate of the process was better than 90 percent. The taste of the treated milk compared favorably with regular milk. Nutritional values were altered somewhat, but animal feeding studies showed no deleterious effects on growth or general health as a result of known changes in the processed milk. The system included storage tanks, ion exchange resin columns, a high-temperature short-time pasteurizer, time and step controllers, and pH controls. Papers were presented on laboratory studies of ion exchange methods, nutritional investigation of milk processed in a pilot plant, microbiological aspects of the fixed-bed process, design and operation of full-scale equipment, problems associated with designing equipment, automation of full-scale equipment, problems associated with quality control and removal efficiency, relationship of the ion exchange process to present day commercial fluid milk processing operations, and additional research and development activities considered for treatment processes.
