Fermentation has become a reliable, cost-competitive, feasible alternative for
large-scale industrial production of many bulk and special organic acids. Electrodialysis with
bipolar membranes (EDBM) technology was considered as a ‘‘green’’ process for organic
acid separation from fermentation broth, which has distinct advantages over other electrolysis-
based technologies. However, review on the new state on this field is limited. This paper
provides an overview of recent progress in application of EDBM process for organic acid
production from 2008 to the latest one, including EDBM process integration, application and
maintenance. Especially, the influence of different operational factors on the performance of
EDBM was systemically discussed. Furthermore, the gaps limiting large-scale field application
of EDBM process were analyzed.
Keywords: Organic acids, electrodialysis, bipolar membrane, fermentation broth, economics.
