I.What is EDI?

Electrodeionization (EDI) is usually considered a water treatment technology that utilizes an electrode to ionize water molecule 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).

II.What It Does

An important application for electrodeionization is the production of pure water and ultrapure water.

III.How It Works

An electrode in an electrochemical cell is referred to as either an anode or a cathode.

The anode is defined as the electrode at which electrons leave the cell and oxidation occurs, and the cathode as the electrode at which electrons enter the cell and reduction occurs. Each electrode may become either the anode or the cathode depending on the voltage applied to the cell. A bipolar electrode is an electrode that functions as the anode of one cell and the cathode of another cell.

Water is passed between an anode (positive electrode) and a cathode (negative electrode). Ion-selective membranes allow the positive ions to separate from the water toward the negative electrode and the negative ions toward the positive electrode. High purity deionized water results.

IV.Advantages:

Continuous productionNo need for acid and alkali regeneratingWithout the emission of acid and alkali solutionStable quality of output waterLow woking costStandard designCompact structureConvenient operation and management

V.Application

These systems cover many applications including power generation,micro-electronies,food and beverage production,and chemical and pharmaceutical manufacturing.
