Bipolar membrane electrodialysis (BMED) is a novel membrane technology, with which H~+ and OH~- could be continuously produced under the effect of applied direct current via water decomposition occurred at the cation-anion interface of the bipolar membrane. Therefore, a variety of specific separation processes could be achieved by different combinations of bipolar membranes and ion-exchange membranes. Compared with conventional technologies, BMED has significant advantages such as high efficiency, environmental friendliness and convenient operation. In this paper, three different working models of BMED are introduced, and the recent progress of BMED in the fields of organic acid production, water desalination, albumen separation and ultrapure water production are discussed together with the prospects for further investigation and development.
