“…Membrane electrical conductance (G) was measured with a specially designed cell (Laboratoire des Matériaux Échangeurs d’Ions, Créteil, France) following the procedure described by Mikhaylin et al [ 27 ]. The NaCl reference solution was 0.5 M. The membrane conductivity was calculated according to Lteif et al [ 28 ] and Lebrun et al [ 29 ] (Equation (1)): R m = R m+s − R s where R m is the electrical resistance of the membrane (in Ω), R m+s the electrical resistance of the membrane and the reference solution measured together (in Ω) and R s the electrical resistance of the reference solution (in Ω).…”

Neokyotorphin (α137-141) is recognized as an antimicrobial peptide and a natural meat preservative. It is produced by conventional enzymatic hydrolysis of bovine hemoglobin, a major component of cruor, a by-product of slaughterhouses. However, during conventional hydrolysis, chemical agents are necessary to adjust and regulate the pH of the protein solution and the mineral salt content of the final hydrolysate is consequently high. To produce this peptide of interest without chemical agents and with a low salt concentration, electrodialysis with bipolar membrane (EDBM), an electromembrane process recognized as a green process, with two different membrane configurations (cationic (MCP) and anionic (AEM) membranes) was investigated. Hydrolysis in EDBM showed the same enzymatic mechanism, “Zipper”, and allowed the generation of α137-141 in the same concentration as observed in conventional hydrolysis (control). EDBM-MCP allowed the production of hydrolysates containing a low concentration of mineral salts but with fouling formation on MCP, while EDBM-AEM allowed the production of hydrolysates without fouling but with a similar salt concentration than the control. To the best of our knowledge, this was the first time that EDBM was demonstrated as a feasible and innovative technology to produce peptide hydrolysates from enzymatic hydrolysis.

“…One of the main mechanisms of overlimiting mass transfer is electroconvection, which not only increases the effective transport of salt ions [8] but also partially suppresses the water splitting at the interface [9], which impedes the process of precipitation in the electrodialyzer chambers [10].…”

“…However, the effect of the surface properties of ion-exchange membranes on the process efficiency has not been studied enough. It was shown in [10] that the hydrophobicity and heterogeneity of the ion-exchange membrane surface lead to the development of electroconvection. This results in an increase in the rate of demineralization at PEF modes.…”

Effect of Surface Inhomogeneity of Ion-Exchange Membranes on the Mass Transfer Efficiency in Pulsed Electric Field Modes

et al. 2020

Despite the growing interest in pulsed electric field modes in membrane separation processes, there are currently not many works devoted to studying the effect of the surface properties and composition of ion-exchange membranes on their efficiency in these modes. In this paper, we have shown the effect of increasing mass transfer using different kinds of ion-exchange membranes (heterogeneous and homogeneous with smooth, undulated, and rough surfaces) during electrodialysis in the pulsed electric field modes at underlimiting and overlimiting currents. It was found that the maximum increment in the average current is achieved when the average potential corresponds to the right-hand edge of the limiting current plateau of the voltammetric curve, i.e., at the maximum resistance of the system in the DC mode. For the first time, the development of electroconvective vortices was visualized in pulsed electric field modes and it was experimentally shown that even at relatively low frequencies, a non-uniform concentration field is preserved at the time of a pause, which stimulates the rapid development of electroconvection when pulses are switched on again. In the case of relatively high pulse frequencies, the electroconvective vortices formed during a pulse lapse do not completely decay during a pause; they only slightly decrease in size.

“…Firstly, PEF technique was experimented to reduce the concentration polarization (CP) which is created when the ionic concentration at one side of the membrane is very low while the ionic concentration is very high on the other side of the same membrane, and increase the ED power efficiency [65]. The reducing of CP leaded also to the decrease of scaling and fouling tendencies especially in the case of ions, charged molecules and colloidal particles and important applications of pulsed current mode emerged as means to mitigate the formation of organic gel or inorganic crystalline films on membrane surface or modulate the mineral membrane fouling growth [66][67][68][69][70][71][72][73][74][75]. In particular, it was found that the use of pulsation with a frequency of the order of 0.1 Hz and an extended relaxation time allows the mitigation of organic fouling in the systems containing humate, lactate, bovine serum albumin (BSA) or whey protein [68,[76][77][78][79].…”

A Review on Ion-exchange Membranes Fouling and Antifouling During Electrodialysis Used in Food Industry: Cleanings and Strategies of Prevention

During the last decades, the interest of using ion-exchange membranes (IEMs) in electrodialysis (ED) technologies has emerged in wastewater treatment, drinking water and process water production as well as food industry and more recently in processes of energy conversion and storage. Like in all membrane technologies, the problem of fouling is one of the limitative phenomena of IEM efficiency and lifetime. It mainly leads to an increase in electrical resistance of ED stacks and consequently to increase operating and membrane replacement costs, which directly affects the cost of the final product. In food industry, the composition of the treated solutions and beverages is most often complex and rich in several organic and inorganic compounds which further increases the risks and effects of fouling. Hence, a better knowledge and understanding of IEM fouling phenomena is not only the key to solve the problems and find adequate solutions, but also is one of the main factors driving membrane technology forward. This review is mainly focused on the organic fouling phenomena of IEMs during ED processes in both food and water treatment industries. It principally presents the main cleaning techniques used in industry or experimented at laboratory scale and the recent strategies of fouling prevention.
