IONPURE® Continuous Electrodeionization

IONPURE was the first to commercialize continuous electrodeionization (CEDI). Discover all that this groundbreaking water treatment technology has to offer for your application.

​What Is CEDI?

Evoqua Water Technologies has spent valuable time, energy, and resources to create a water treatment option that doesn’t use traditional mixed-bed deionization technologies. To put it simply, conventional ion exchange is a practical treatment option when high-flow and high-conductivity requirements aren’t critical. For other situations, continuous electrodeionization is a cost-effective alternative.

So, what exactly is continuous electrodeionization by IONPURE? It’s a CEDI water treatment technology that utilizes resin, electricity, and ion exchange membranes to deionize water by separating impurities from the water. Most traditional water purification technologies and equipment utilize chemicals to complete the process. Our state-of-the-art technology, on the other hand, does not.

​Discover the Difference of CEDI

What’s the difference between conventional mixed-bed deionization and CEDI? First and foremost, conventional deionization (DI) methods use bottles filled with resin. These bottles require maintenance in manners that our CEDI technology does not. With the traditional methods, you’re required to call a service provider to exchange the DI bottles regularly. Some companies choose to handle the regeneration of their DI bottles, which requires the use of expensive chemicals, as well as an extensive amount of time from a laborer.

Time is money. Therefore, you cannot afford to shut down operations to have your DI bottles exchanged. Nor should you worry about spending money on expensive chemicals to regenerate your bottles. Our CEDI modules eliminate the need. In addition, our technologies also eradicate the waste neutralization steps. It’s true that the upfront capital equipment costs are typically greater with continuous electrodeionization than the costs of the conventional DI systems. Once installed, however, you’ll see a drastic decrease in your operating costs because the system doesn’t require the use of regeneration chemicals, or the time and money associated with labor and maintenance.
