Abstract
Electrodialysis with bipolar membranes (EDBM) is a kind of technology that integrates solvent and salt dissociation. It can realize salt conversion without second salt pollution or provide H+ and OH-/alkoxide ions in situ without salt introduction. Thus, it inherently possesses economical and environmental benefits. Moreover, its technological compatibility gives rise to new functions when it couples with other technologies, such as complexion, ion exchange, extraction, and adsorption. In view of the above peculiarities, EDBM has found many interesting applications in chemistry, food processing, biochemical industries, and environmental protection. However, its development has been restricted by such factors as lack of recognition of its contribution to industrial ecology, high membrane cost, insufficient research investment, and scarce operation experience. This paper compiles an introduction to this technology from the perspective of industrial ecology and conducts an extensive examination into EDBM applications. Its purpose is to gather synergic strength from academia, industry, and government to perfect EDBM for sustainable development.
