Deionization Deionization (DI), and constant electrodeionization (CEDI) are effective methods of improving upon the chemical high quality characteristics of water by eliminating cations and anions. DI techniques have charged resins that involve periodic regeneration by having an acid and foundation. Generally, cationic resins are regenerated with both hydrochloric or sulfuric acid, which swap the captured positive ions with hydrogen ions. Anionic resins are regenerated with sodium or potassium hydroxide, which substitute captured adverse ions with hydroxide ions.
