EDI-Series Electrodeionization Systems are a superior option to conventional mixed-bed deionization. Ultrapure water is processed by taking reverse osmosis permeate 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 concentrate stream.
These EDI systems do not require regeneration and there are no chemicals used for operation. EDI-Series Electrodeionization Systems are available in four flow ranges up to 7 gallons per minute (GPM). These systems feature a modular design, so they can be easily expanded to accommodate various requirements. Additionally, systems can be arranged in parallel for increased capacities.
