Siemens EDI Membrane Stack - IP-LXM04Z
1. Introduction to Siemens EDI Membrane Stack
The Siemens EDI Membrane Stack is a water treatment device that uses Continuous Electrodeionization (CEDI) technology. CEDI is an advanced deionization technology that combines ion exchange resins with ion migration under the influence of an electric field. Specifically, when fresh water enters the fresh water chamber, the ions within it undergo ion exchange with the mixed bed resin, thus detaching them from the water. These exchanged ions are attracted by electricity, with cations migrating towards the cathode through the cation exchange membrane and anions migrating towards the anode through the anion exchange membrane, entering the concentrated water chamber and being removed from the fresh water. This process creates a dynamic equilibrium within the module, where the resin is both consumed and regenerated. Compared to traditional ion exchange that requires chemical regenerants, CEDI technology can operate continuously without the need for chemical regenerants, making it simpler to operate and significantly reducing operating costs.
