“…For the five-compartment assemblies ( Fig. 1b), apart from ERS, the stack configuration was composed of two separate loops: D (2, 4) and C (1,3,5); namely the flowing streams circulating in diluted compartments 2 and 4 (D (2, 4)) and concentrated compartments 1, 3 and 5 (C (1, 3, 5)). The initial composition of the streams is given in Table 1b.…”

“…The electrodialysis technologies (ED), such as conventional electrodialysis (CED) [2,3], electrometathesis (EMT) [4], electro-ion substitution (EIS) [5], electrodialysis with bipolar membranes (BMED) [6] and electrodeionization (EDI) [4,7], have been proved their advance in the fields of amino acid production. According to their application, the two most important functions of ionexchange membrane separation processes are demineralization and concentration of amino acids [8].…”

A B S T R A C TElectrodialysis (ED) with heterogeneous bipolar membranes (BPMs) was studied experimentally on a laboratory scale in order to examine the recovery of the sodium sulfate solution into sulfuric acid and sodium hydroxide. The capacity of the system was evaluated in terms of its dependence on membrane configuration, product concentration, temperature, and circulation flow rate. A preliminary economic evaluation of ED with a heterogeneous BPM in a uranium ore mining wastewater treatment plant was also carried out. This process is primarily used in cases where the purity of the sulfuric acid and sodium hydroxide recycled does not play a significant role and the high costs of the homogeneous BPMs negatively affect the economy.

BACKGROUND: Commercially lysine (Lys) is produced as lysine monohydrochloride (LysCl). The presence of chloride ion (Cl−) in Lys makes it unfit for use in pharmaceutical and livestock feed industries. Various separation methods are required to achieve Lys from fermentation broths. This paper describes an electro‐membrane reactor with three compartments (EMR‐3) for the conversion of LysCl into Lys by in situ ion substitution and separation. RESULTS: The conversion of LysCl into Lys in EMR‐3 is achieved by in situ ion substitution and separation using organic‐inorganic hybrid anion‐exchange membrane (AEM). It is found that the rate of Lys formation is dependent on applied current densities and LysCl concentration. The 96.2% Lys is recovered and low energy (2.07 kWh kg−1) is consumed during the conversion of 0.10 mol L−1 LysCl in EMR‐3 at 10 mA cm−2. Moreover, high current efficiency (93.02%) is achieved under the similar experimental conditions. CONCLUSIONS: On the basis of process parameters (high Lys recovery and CE and low W), it is concluded that the developed electro‐membrane reactor can be efficiently applied for the conversion of LysCl into Lys in an economically viable manner. © 2012 Society of Chemical Industry
