“…As an alternative technique, electrodialysis is not economical for treating dilute solution because of its high electrical resistance and the development of concentration polarization phenomena. The combination of electrodialysis and ion-exchange methods (electro-deionization) can be applied to the removal of Ni(II) ions [47][48][49][50][51][52][53][54][55], from diluted solutions. Electrodeionization includes two processes, which are carried out simultaneously: concentration of ions in the ion exchanger (sorption) and transport of ions through the ion exchanger and membrane system caused by a potential gradient and presence of oxidizing impurities in the solution to be purified results in destruction of the resin.…”

“…However, other arrangements with few compartments (three or some more) in total, including the electrode ones, were developed. Among them, some units exploit electrode water electrolysis to deliver H + ad OH − for the IXRs electro-regeneration [45][46][47][48][49][50], thus differing considerably from conventional ED. Limitations in EDI performance may derive from small current efficiencies in operations with high water dissociation [9], and from inhomogeneous flow distributions [42].…”

This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes. ED of both conventional or unconventional fashion has been tested to treat several waste or spent aqueous solutions, including effluents from various industrial processes, municipal wastewater or salt water treatment plants, and animal farms. Properties such as selectivity, high separation efficiency, and chemical-free treatment make ED methods adequate for desalination and other treatments with significant environmental benefits. ED technologies can be used in operations of concentration, dilution, desalination, regeneration, and valorisation to reclaim wastewater and recover water and/or other products, e.g., heavy metal ions, salts, acids/bases, nutrients, and organics, or electrical energy. Intense research activity has been directed towards developing enhanced or novel systems, showing that zero or minimal liquid discharge approaches can be techno-economically affordable and competitive. Despite few real plants having been installed, recent developments are opening new routes for the large-scale use of ED techniques in a plethora of treatment processes for wastewater.

“…The result showed that the mineral ions contained in the diluted FME could be effectively removed in the two ED system. The electrical conductivity difference between the diluted and concentrated solutions indicated that the ion exchange resins filled in the PBED system could enhance the ion removal of the diluted solution due to its adsorption and electric conductibility, especially at low ion concentrations (Spoor et al, 2002).…”
