“…The obtained results are comparable to the results of Merkel et al (). The authors conducted EDBM of demineralised acid whey nanofiltration (NF) retentate.…”

“…Merkel et al () reported similar membrane fouling deposition in EDBM cell configuration where the acid whey stream was in contact with the anion‐exchange layer of BPM. The authors found that the content of typical mineral foulant elements, calcium and phosphorus was surprisingly low, while carbon and nitrogen significantly contributed to the fouling matter.…”

“…These results are similar to those obtained in the present study (76.4 ± 10.5 and 45.3 ± 5.1 kW·h per t of dry matter for EDBM of 70 and 90% predemineralised concentrated acid whey, respectively). However, the actual degree of demineralisation was higher in whey NF retentate (Merkel et al ), as far as the authors did not account the demineralisation due to NF processing.…”

“…These phenomena are sufficiently covered in respective reviews (Suwal et al ; Mikhaylin and Bazinet ). The fouling issue is also known in EDBM applications (Wang et al ; Mikhaylin and Sion ; Haddad et al ; Dufton et al ; Merkel et al ). It is important that the electrogeneration plays a crucial role in fouling formation.…”

A nonreagent method for the regulation of the pH of acid whey was investigated at a laboratory scale. Acid whey and concentrated acid whey were subjected to electrodialysis with bipolar membranes in order to raise the pH value to 6.5. Demineralised whey underwent identical processing. The deacidification rate as per tonne of a dry matter was similar for acid whey and concentrated acid whey treatment at 70% and 90% degrees of demineralisation. We estimated the energy consumption of electrodialysis. The preliminary demineralisation of whey significantly increased the energy efficiency of whey pH correction. Additionally, we observed substantial fouling on the diluate side of bipolar membranes after whey treatment.

Bipolar membrane electrodialysis (BMED) is a promising technique for upgrading traditional manufacturing procedures and achieving a circular economy. However, the industrial applications of BMED technology have been restricted by the large consumption of expensive bipolar membranes and the unmatching behavior between water splitting and ion migration. Herein, we proposed a novel asymmetric bipolar membrane electrodialysis (ABMED) to regulate the water splitting in the bipolar membrane and orientational ion migration in the electrodialysis (ED). It was found that the ABMED exhibited comparable performances to BMED for acid/base production when the area of the bipolar membrane was reduced to 50% of the monopolar membrane.

Ultrafiltered (UF) milk permeate was concentrated by reverse osmosis (RO). UF and UF + RO samples were then desalted by electrodialysis (ED) to three levels of desalination: 1, 2.5, and 4 % of ash in the dry matter. Ions were analyzed by a new high‐performance liquid chromatography method, which enables simultaneous estimation of cations and anions. ED of UF permeate has some advantages over that of UF + RO samples, including a shorter ED time and a higher average salt flow rate, but RO treatment of UF permeate before ED enables the processing of larger volumes of UF permeate. Therefore, ED of milk permeate, particularly after RO, improves the handling characteristics and may offer advantages for further processing of secondary dairy products.
