Regeneration of ion exchange resins
When all the available Na+ ions have been replaced with calcium or magnesium ions, the resin must be re-charged by eluting the Ca2+ and Mg2+ ions using a solution of sodium chloride or sodium hydroxide depending on the type of resin used. For anionic resins, regeneration typically uses a solution of sodium hydroxide or potassium hydroxide. The waste waters eluted from the ion exchange column containing the unwanted calcium and magnesium salts are typically discharged to the sewage system.
ECO TECHNOLOGY uses a sodium chloride solution to re-charge the resin, with our new technology of Vortech softeners they have an automatic control valve to regenerate soft water, therefore you can leave it to us and not worry about it.
