[0002] EDI ultrapure water, that is, ultrapure water obtained by the electrodeionization water purification technology, is a new desalination process that combines electrodialysis and ion exchange. Specifically, the EDI ultrapure water system is mainly composed of a partition, anion membrane, cation membrane and ion exchange resin. Under the action of the DC electric field, the dielectric ions in the water will move in a directional manner and be captured by the ion exchange resin, thereby achieving water desalination and purification. EDI ultrapure water equipment has many advantages, such as better water quality than conventional ion exchange methods, low operating costs, and small footprint. Therefore, it is widely used in many fields, including the electronics industry, power industry, semiconductor industry, new energy industry, chemical industry, food industry, electroplating industry, and laboratories.
