The fouling, in particular the organic fouling of anion exchange membranes (AEMs), is a serious problem in electrodialysis (ED). In this paper, we attempted to improve the antifouling potential of AEM by surface modification with polydopamine (PDA). The antifouling potential was evaluated by the tran

Generally, a membrane is a composite and is made by forming a skin layer on a support. Then, the support will also affect the rejection, since the support affects the ion flux. In practical terms, however, the effect of support on membrane performances is almost always neglected. In this paper, the

An equation of rejection curve was derived for a membrane system where the membrane charge strongly affected the partition of ions into the membrane surface. The equation predicted that the rejection varied linearly with the inverse of the volume flow. The equation was applied to the experimental da

It has been reported that the membrane charge of amphoteric membranes such as inorganic membranes depends on the pH and the electrolyte in the bulk solution. To explain these phenomena, we have proposed the advanced amphoteric membrane (AAM) model where the effective membrane charge is determined by
