7GPM Electrodeionization EDI Water Purification System Ultrapure Water Machine
The EDI- Series Electrodeionization systems are a superior option to conventional mixed layer deionization. Ultrapure water is processed by taking reverse osmosis permeation water and feeding it into the EDI System which uses electricity to continuously drive ions through deionization resins and ion selective membranes, thus producing a small stream of concentrate.
These EDI systems require no regeneration and there are no chemicals used in operation. The EDI - Series Electrodeionization systems are available in four flow ranges up to 7 gallons per minute (gal/mn). These systems feature a modular design, so they can be easily expanded to accommodate various requirements. Additionally, the systems can be arranged side by side for increased capacities.
