Ion exchange for the remediation of perchlorate‐contaminated drinking water
This research explored options for removing perchlorate from drinking water using commercially available ion exchange resins. Experimental data provided perchlorate selectivity, capacity, and thermodynamic properties of the resins. With these data, computer models using equilibrium multicomponent chromatography theory evaluated treatment options based on different water chemistry and operating characteristics; computer predictions were validated by bench‐scale tests. Three treatment approaches emerged as viable options for removing perchlorate to concentrations below proposed maximum concentration limits: (1) partial exhaustion‐regeneration using polyacrylic resins, with a process similar to current nitrate treatment techniques, (2) partial exhaustion–regeneration using polystyrene resins with elevated temperature regeneration, and (3) use of highly perchlorate‐selective resins with resin replacement following exhaustion.
