7GPM Electrodeionization EDI Ultrapure Water System with 90% Recovery Rate and 18.2 MΩ·cm Water Quality
The EDI-Series Electrodeionization systems represent a superior alternative to conventional mixed bed deionization. These advanced systems process ultrapure water by taking reverse osmosis permeate water and using electrical current to continuously drive ions through deionization resins and ion-selective membranes, producing high-purity water with minimal waste stream.
- No chemical regeneration required during operation
- Chemical-free continuous operation
- Modular design for easy expansion and customization
- Available in four flow ranges up to 7 gallons per minute
- Side-by-side arrangement capability for increased capacities
