CRUD ABSORPTION BY ION EXCHANGE RESINS
The resuits of investigations to determine effects of crud absorption on demineralizer life are presented. The tests consisted of contacting known amounts of ion exchange resin; either hydrogen form cation, hydroxyl form anion, or mixed bed hydrogen-hydroxyl, with knnow amounts of synthetic crud for periods up to 10 weeks. On the basis of results from these tests, it was concluded that no serious problem exists as a result of crud absorption by mixed bed restns. Resin capacity losses for crud concentrations encountered to date in mixed bed resins would be less than 5% of the total capacity. Since design life calculations for demineralizer are probably inaccurate by at least 5 to 10%, it is recommended that no allowances, for crud absorption, be mede in the demineralizer size unless crud concentrations in excess of 5g per 100 nfl of cation resin are expected to be found in the ion exchange resin bed.
