“…This result can be explained by the concentration polarization phenomenon which is more important at high concentration (Sadrzadeh and Mohammadi 2008). As demonstrated in previous studies (Kabay et al 2002;Banasiak et al 2007;Sadrzadeh and Mohammadi 2008;Ben Sik Ali et al 2010a), the number of ions transported through the membranes are almost the same but total amounts of salts are quite different from the different treated solution. As known, the calculation of DR depends strongly on the initial feed concentration and the amount of transported ions.…”

“…Sadrzadeh and Mohammadi (2008) and Ben Sik Ali et al (2010a) observed that the salt percent removal increases when the flow rates decrease. They suggested that for low flow rates the residence time of ions in the dilute compartment increases.…”

“…Many factors influence the ED performance such as applied potential (Elmidaoui et al 2002;Banasiak et al 2007), salt concentration (Banasiak et al 2007;Shady et al 2012), flow rate of dilute compartment and temperature (Sadrzadeh and Mohammadi 2008;Ben Sik Ali et al 2010a;Shady et al 2012).…”

“…In most previous studies, the effect of some parameters on ED process is determined by varying one parameter by time, maintaining all the other parameters constant (Elmidaoui et al 2002;Kabay et al 2008;Ben Sik Ali et al 2010a, b). Then the best value achieved by this procedure is fixed and other parameters are varied by time.…”

The aim of this work is to study the desalination of brackish water by electrodialysis (ED). A two levelthree factor (2 3 ) full factorial design methodology was used to investigate the influence of different physicochemical parameters on the demineralization rate (DR) and the specific power consumption (SPC). Statistical design determines factors which have the important effects on ED performance and studies all interactions between the considered parameters. Three significant factors were used including applied potential, salt concentration and flow rate. The experimental results and statistical analysis show that applied potential and salt concentration are the main effect for DR as well as for SPC. The effect of interaction between applied potential and salt concentration was observed for SPC. A maximum value of 82.24% was obtained for DR under optimum conditions and the best value of SPC obtained was 5.64 Wh L -1 . Empirical regression models were also obtained and used to predict the DR and the SPC profiles with satisfactory results. The process was applied for the treatment of real brackish water using the optimal parameters.

“…As mentioned before, the electrodialysis is an electro membrane process especially used for the desalination of brackish water and sodium chloride recovery from sea water [10,13]. The transfer of ionic components from aqueous solution through ion exchange membranes is carried out under the driving force of an electrical field.…”

The continuous increase of environmental regulations make interesting to find effective and efficient methods for processing effluents containing metal ions. This research focuses on cadmium removal from brackish water by an electro-membrane process: The electrodialysis. Experiments were carried out on synthetic brackish water solutions and using a laboratory scale electrodialysis system. The influence of several parameters on process efficiency was investigated. The efficiency of this process was assessed by the determination of five parameters: The demineralization rate, the removal rate and the transport flux of cadmium, the current efficiency and the specific power consumption. The applied voltage, the feed flow rate, the pH and cadmium initial concentration of the feed solution have a significant effect on the process efficiency and mainly on the cadmium transfer from dilute to concentrate compartment. In contrast, feed ionic strength seems to affect only the SPC and not the R(Cd).
