Continuous Electro deionization (CEDI) is a chemical-free, self-regenerating technology used to provide a consistent flow of high-quality deionized water.
With the growing costs of chemicals for regeneration and waste neutralization, and heightened safety concerns with handling hazardous chemicals, many industrial customers began seeking an alternative to cost-prohibitive, on-site regenerable ion exchange for creating ultrapure water. IONPURE®, an Evoqua brand, offers that solution. The first to commercialize CEDI in 1987, we have provided thousands of modules that deliver ultrapure water at capacities ranging from 0.013 m3/h (0.06 gpm) to 22.7 m3/h (100 gpm).
In short, CEDI is a water treatment process that uses a combination of ion-exchange resins, ion-exchange membranes, and direct current to continuously deionize water without the need for chemicals. The avoidance of chemicals helps to reduce the systems’ operating and maintenance costs and, therefore, improve your bottom line.
The key benefits of CEDI
- Chemical-free water treatment
- Continuous water flow with consistent, known water quality
- Zero resin bed regeneration downtime
- Fast system installation and startup
- Standardized systems mean short lead times
- Flexible system design with high flow rates
