Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water.

Electrodeionization (EDI) is a continuous, chemical-free process of removing ionized and ionizable species from feedwater using DC power.

Electrodeionization is a water treatment technology that removes ionizable species from water using electrically active media and an electrical potential difference. It combines two well-established technologies: ion exchange resins and electrodialysis.

EDI is a process which combines semi-impermeable membrane technology with ion-exchange media to provide a high efficiency demineralization process.

2024年9月10日 · Electrodeionization (EDI) is an advanced water treatment technology designed to produce ultrapure water by combining ion exchange membranes, ion exchange resins, and electrical current. EDI is often used in industries where water purity is critical, such as pharmaceuticals, power generation, and electronics manufacturing.

One type of water treatment is electrodeionization (EDI), which uses ion exchange membranes, direct current electricity and ion exchange resin to effectively deionize water. The resulting water is suitable for a wide range of applications across many different industries.

What is Electrodeionization (EDI)? EDI technology has grown in popularity in water purification industry. It effectively removes impurities from water using a unique combination of semi-permeable membranes, ion exchange resins and a direct electric field.

2023年12月15日 · What is Electrodeionization? Electrodeionization (EDI) is an electrically-driven water treatment technology that uses electricity, ion exchange membranes and resin to remove ionized species from water.

Electrodeionization works in applying functional currents to eradicate ionized substances from water bodies, while simultaneously regrowing the ion exchange media. An EDI water system is usually applied after the usage of a reverse osmosis system or even a double pass ro system.

2014年6月20日 · Electrodeionization is an ionic separation technology that initially emerged ∼50 years ago. In an early application, it was utilized to remove metallic species from radioactive wastewater; however, a poor understanding of its functional kinetics has slowed its development and applications.
