Process intensification through the combined use of electrodialysis (ED) and ion-exchange resin (IER) hybrid process, called continuous electropermutation (CEP), was employed to remove Ni(II) cations from water. To carry out this process, Amberjet 1200 H cation-exchange resin was introduced into the feed compartment of the ED cell. The applied electrical field improves the mobility of species and ensures a continuous resin activation which is a main drawback in IER process. Furthermore, the IER incorporated in the ED cell enhances the conductivity of the feed water, therefore it extends the range of ED which could be applied for the recovery of ions from very low concentration wastewaters. The effects of some factors such as the type of regenerating electrolyte, current density, quantity of resin incorporated in the conducting space and concentration of Ni(II) at the inlet were investigated. The efficiency of CEP and ED for Ni(II) removal was expressed in terms of recovery rate and concentration factor.
