Summary
S>Fixed-bed and continuous ion-exchange flowsheets were developed for treating low-radioactivity-level process water. By using a combination of weak- acid and strongacid type ion-exchange resins with bicarbonate waters, it was possible to use nitric acid regenerant stoichiometrically. The resulting waste without evaporation was a neutral nitrate salt about 2N in strength. Evaporation was recommended so the resulting waste would be a mass of crystals rather than liquid. Decontamination of Cs/sup 137/ and Sr/sup 90/ was about 10/sup 3/ even when fluoride was 10 ppm and polyphosphate 5 ppm. About 95% of the rare earths was removed when these complexing agents were absent but none when present. A 3/ 4 million gallon per day plant was cost estimated as follows for water 100 ppm in hardness and 23 ppm sodium in cents per 1000 gallons: capital 5.5 cents and operating 34 cents, including solid waste disposal.
