The influence of resin regeneration on nitrates removal effectivity from drinking water
Summary. The objective of the study was to investigate the capacity of selective resin IONAC SR-7 (Sybron Chemicals Inc., USA) to remove nitrates from drinking water and to optimize the regeneration process, which is based on an estimation of optimum brine concentration and flow rate, which would increase resin regeneration efficiency. Based on the results, 1 dm3 resin can remove 0.7 eq nitrates. Therefore, the determined value of ion-exchange working capability under particular process conditions (12% NaCl solution and a flow rate of 4 BV/h) is 87.5% of the theoretical ion-exchange capability for the examined resin. It was found that as a result of resin partial regen-eration its working sorption capacity decreased to 0.56 meq/ml, which was about 70% of theo-retical resin ion-exchange capacity. This represented a 50% reduction of the volume of environmentally harmful waste after regeneration.
