EDI Module For Continuous Ultrapure Water Production

EDI Module for Continuous Ultrapure Water Production

I.Overview

EDI is often combined with reverse osmosis and other purification devices to remove ions from water. The ion exchange resin in the EDI module can be divided into two parts: one part is called the working resin, and the other part is called the polishing resin. The boundary between the two is called the working front. Working resins are responsible for removing most of the ions, while polishing resins are responsible for removing more difficult ions, such as weak electrolytes. Ultrapure water prepared by EDI systems can have a conductivity of up to 15-18.2 MΩ ·cm. EDI can be operated continuously or intermittently.

II.EDI Features:

• Using special resin and anion-cation membranes, under the same current, enabling lower operating voltage, energy-saving (power-saving), and environmentally friendly, and the service life is long.
• No salt addition and concentrate water circulation system;
• High-strength ion exchange resin is used, which has high exchange capacity and strong selectivity.
• Adopt a high-strength homogeneous ion exchange membrane, with high strength and superior aging resistance;
