Electrodeionization (EDI) is usually considered a water treatment technology that utilizes an electrode to ionize water molecules and separate dissolved ions (impurities) from water. It differs from other water purification technologies in that it is done without the use of chemicals and is usually a tertiary treatment to reverse osmosis (RO).
