Abstract

This article highlights results from an ion exchange (IX) pilot-plant study that evaluated bicarbonate-form anion exchange resin (AER) with sodium bicarbonate (NaHCO3) regeneration for dissolved organic carbon (DOC) removal. Sodium chloride (NaCl) is the conventional regeneration salt; however, NaHCO3 could be used as an alternative to reduce the environmental impacts associated with NaCl brine disposal. In a comparison of chloride-form AER and bicarbonate-form AER, results indicated that chloride-form AER and bicarbonate-form AER have a similar affinity for DOC; chloride-form AER treats more bed volumes before breakthrough than bicarbonate-form AER; chloride-form AER is regenerated 10–48% more efficiently with NaCl compared with bicarbonate-form AER regenerated with NaHCO3; polyacrylic AER is regenerated more efficiently than polystyrene AER using both NaCl and NaHCO3; and the total cost of using NaCl and NaHCO3 is comparable when brine disposal is considered. Results from this study provide guidance for small water systems considering IX treatment.
