Electrodeionization Equipment. Location: Home >Products Electrodeionization Equipment 切换布局 Electrodeionization Equipment EDI (Electrodeionization) is a revolutionary high-tech water treatment technology, which neatly combines electrodialysis, ion exchange, and membrane separation. EDI can be used for continuous water purification. It doesn’t require chemical regeneration, like ion-exchange units and can be fully automated. This is an easy-to-use environmentally friendly technology. It has been mainly used in pharmaceutical, electrical, power generation, chemical, and several other industries where high-resistive water (as low as18 MΩ*cm) is required, but becomes more and more popular for conventional water treatment aiming for up-to-date green technologies with lowest environmental impact.
