What is the principle of EDI deionized water technology?

Sep 22, 2017

EDI electric deionized water technology is a combination of electrodialysis and ion exchange resin desalination of new technology, China also known as packed bed electrodialysis. So what is the principle of EDI deionized water technology?

EDI electric deionized water technology is the principle of the electrodialysis in the fresh water chamber filled with yin, cationic ion exchange resin, the electrodialysis and ion exchange combined in a device to become a consortium. As the fresh water chamber, the ion exchange agent particles continue to exchange the role of the role of regeneration, and constitute a "particle channel", active ion activity, so that the conductivity of fresh water chamber greatly increased, thus weakening the polarization of electrodialysis , To improve the limit current of the electrodialyser, to achieve a high degree of water purification. In addition, since the fresh water chamber is filled with an ion exchanger, the velocity of the water in the fresh water chamber is greatly increased as compared with that in the ordinary electrodialysis, and the ion exchanger particles are agitated and agitated to promote the diffusion of ions and improve the water Mechanical conditions, but also lead to an increase in the conductivity of fresh water chamber.
