Electrodeionization (EDI)

Electrodeionization (EDI) is a continuous process that utilizes an applied current to remove ionized and ionizable species from a water source while continuously regenerating the ion exchange media. Ions are transferred to concentrate chambers by the use of cationic and anionic semi-permeable membranes and flushed out of the module through a continuous waste stream. Dilute product water moves through the dilute chamber and out of the module. An on-skid rectifier will apply a voltage to remove dissolved impurities.
