| Abstract: | This article analysed water dissociation and its relating mechanism in the ED and EDI processes. The H + and OH-ions producing by water dissociation may self-regenerate ion-exchange resins. Two applications are introduced briefly; the developed EDI technology and the spreading electro-regeneration technology of ion-exchange resins. |
