AXEON® EDI – Series Electrodeionization Systems are a superior option to conventional mixed-bed deionization. EDI does not require regeneration and there are no chemicals used for operation. 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.
The AXEON EDI – Series Electrodeionization Systems are available in four flow ranges up to 7 gallons per minute (GPM). Additional systems can be arranged in parallel for increased capacities.

Note: EDI Systems must have a reverse osmosis permeate feed at 30 -40 psi and a flow rate that is 10% greater than the rated product flow of the EDI.
A. FCE = Conductivity + 2.79 (CO2 ) + 1.94 (SiO2). Example: Conductivity = 5.0µS / cm, CO2 = 3.5 mg / l, SiO2 = 0.5 mg / l, FCE = 5.0+2.79 (3.5)+1.94 (0.5) = 15.71µS / cm Note: Conductivity (µS / cm) ~ 2.22 TDS (mg / l)
