EDI Module for Ultra-Pure Water Preparation

The EDI module is an efficient device used for water treatment, primarily applied in the ultra-pure water preparation stage following reverse osmosis (RO) systems. It combines ion exchange and electric separation technologies, utilizing an electric field to drive ions through specialized membranes, while operating continuously without the need for chemical regenerants, thereby effectively removing salts and other ions from water. This technology is particularly suitable for applications with extremely high water quality requirements, such as semiconductor manufacturing, power industry, and pharmaceutical sector, and is widely adopted due to its environmental friendliness, efficiency, and the ability to continuously provide pure water.

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.
