Scientific Research and Reviews

In Electrodeionization is used in various water treatments due to its low energy consumption, high efficiency and cleanliness. The application of EDI in various water treatments, including heavy metal wastewater, ammonia nitrogen wastewater, salty wastewater, and organic wastewater purification, are reviewed. Ion exchange resins and membranes are important factors influencing the performance of EDI. The research progress on ion exchange resins and membranes in EDI is described, focusing on the solution to the membrane fouling problem in EDI process. Reducing and preventing membrane pollution in EDI is the focus of current research. Solving membrane pollution problem will greatly promote the development and application of EDI.

Keywords: Electrodeionization; Ion exchange resin; Membrane fouling
