As a result of reserch and development works carried out in the past nearly half century, the elelctrodialysis technology has been commercialized in wide industrial fields, and is still utilized for seawater concentration in salt manufacturing, desalination of brackish water, recovery and reuse of wastewater, and demineralization of nonelectrolyte and so on. Further, paticular membrane of special property is applied for the separation of strong acid or alkali in diffusion dialysis process.<BR>For the realization of above mentioned application of the ion-exchange membrane, not only innovation of membrane itself but also improvement of electrodialysis equipment and development of design technology of the process played major roles.<BR>This paper introduces briefly some results of development works in the fields of application technique, mainly carried out by the R & D group, the author was responsible for the works.
