The EDI module utilizes an electric field to direct the migration of cations and anions in water, achieving deep deionization through ion exchange membranes, ultimately producing ultra-pure water with a resistivity of up to 15 MΩ·cm or higher. The advantages of this technology lie in its continuity and environmental friendliness, eliminating the need for acid-base chemical regeneration found in traditional methods, thereby reducing the generation of chemical waste.
