  • Electrodeionization

    Electrodeionization (EDI) is a water treatment technology that has gone from an unproven and unknown commodity to one that has revolutionized the industry in the past 20 years. The technology was first introduced to the market in 1987 by Ionpure Technologies. EDI is used in small and large applications. Laboratories use EDI in systems as low as 360 gallons per day (gpd), while power plants, ...
