Electrodeionization (EDI) is a water treatment technology that removes ions and impurities from water through the application of an electrical field. It is commonly used as a method for producing high-purity water, especially in industries such as pharmaceuticals, electronics, and power generation. The EDI process typically involves the following components: 1. **Ion Exchange Resins**: EDI units contain ion exchange resins that can attract and hold charged ions (cations and anions) from the water.
