“…Despite its wide field of applications, two current problems in expanding ED are the fouling of membranes, which causes deterioration in the membrane performance [2,3], and the concentration-polarization (CP) phenomenon, this latter locking ED intensification [4]. Membrane fouling is generally caused by the movement of foulants toward ion-exchange membranes (IEMs), where their deposition on the membrane surface is dependent on the electrochemical interaction between the surface and the foulants present in the treated solution [2,5]. CP is originated by a difference between the ion transfer numbers in the solution and in the membranes, leading to a variation of the electrolyte concentration near the membrane surface and a considerable potential drop in the polarized regions (Nernst layer) that limit the efficiency of electrodialysers [4].…”

“…Some of the products manufactured using ED include dairy goods, wine, fruit juice, and sugar [1]. ED is widely used for the desalination of brackish water [2,3], and has been shown to be suitable for the concentration of high-salinity feeds in the production of salt [3,4].…”

Electrodialysis (ED) is a desalination technology with many applications. In order to better understand how the energetic performance of this technology can be improved, the various losses in the system should be quantified and characterized. This can be done by looking at the entropy generation in ED systems. In this paper, we implement an ED model based on the Maxwell-Stefan transport model, which is the closest model to fundamental equations. We study the sources of entropy generation at different salinities, and locate areas where possible improvements need to be made under different operating conditions. In addition, we study the effect of the channel height, membrane thickness, and cell-pair voltage on the specific rate of entropy generation. We express the second-law efficiency of ED as the product of current and voltage utilization rates, and study its variation with current density. Further, we define the useful voltage that is used beneficially for separation. We derive the rate of entropy generation that is due to the passage of ions through a voltage drop, and we investigate whether voltage drops themselves can provide a good estimate of entropy generation.

“…Alternatively, electrodialysis has been successfully demonstrated to recover lactic acid from fermentation broths [70,71], as well as to demineralize sweet whey prior to whey powder production [72,73]. However, ED applications are still in their infancy, and its potentialities have not been completely exploited probably because of the high specific electromembrane costs or their short lifetime [74].…”

Dairy industry is considered as an important food industry that provides various kinds of nutritionally rich dairy products for all age groups. Beside these nutritive values, dairy industry is contemplated as a good source of raw materials for other industries. Most importantly, dairy industry employs environment-friendly and energy-saving technologies. Membrane separation technology being one of those also focused on a cost-effective and environment-friendly manner, which can be widely applied in dairy industry for many useful purposes. In this chapter, we first define and classify the membrane separation technology and then comprehensively describe its applications, for instance, component separation, filtration, removal of bacteria, and wastewater treatment in dairy industry.
