Evaluating the secondary effects of magnetic ion exchange: Focus on corrosion potential in the distribution system

► MIEX treatment increases the chloride-to-sulfate mass ratio (CSMR). ► MIEX treatment has a minor effect on the Larson-Skold Index (LI). ► Brine in the process train from regenerated resin causes the CSMR and LI to vary. ► MIEX resin can rerelease previously removed anions when raw water quality fluctuates. ► Corrosion parameters are useful tools for designing water treatment systems.
