Factors Influencing the Formation of Salicylic Acid by Bipolar Membranes Electrodialysis [PDF]

open access: yesMembranes, 2022
Salicylic acid is an intermediate product in the synthesis of dyes, medications and aspirin. An electrodialysis module has been constructed with commercial cationic, anionic and bipolar membranes for the conversion of sodium salicylate into salicylic ...

Asymmetric Bipolar Membranes in Acid−Base Electrodialysis [PDF]

open access: yesIndustrial & Engineering Chemistry Research, 2002
In this experimental study, the influence of asymmetric bipolar membranes on the salt impurities in the acid and base product is investigated. The thickness of one, the other, or both ion-permeable layers of a bipolar membrane is increased. With increased layer thickness, the current-voltage curves of the electrodialysis repeat unit recorded in a pilot-

Electrodialysis Desalination with Simultaneous pH Adjustment Using Bilayer and Bipolar Membranes, Modeling and Experiment

open access: yesMembranes, 2022
A kinetic model of the bipolar electrodialysis process with a two-chamber unit cell formed by a bilayer (bipolar or asymmetric bipolar) and cation-exchange membrane is proposed.

Identification of Fouling Occurring during Coupled Electrodialysis and Bipolar Membrane Electrodialysis Treatment for Tofu Whey Protein Recovery [PDF]

open access: yesMembranes
Tofu whey, a by-product of tofu production, is rich in nutrients such as proteins, minerals, fats, sugars and polyphenols. In a previous work, protein recovery from tofu whey was studied by using a coupled environmental process of ED + EDBM to valorize ...

Resource utilization of high-salinity mine water through the membrane-integrated process based on bipolar membrane electrodialysis [PDF]

open access: yesMeitan xuebao
In the context of “zero discharge” of mine water and the reverse distribution of coal and water resources in the western mining areas, the direct discharge of high-salinity mine water without proper treatment not only causes immeasurable damage to the ...

Advances in Physicochemical and Biological Treatment of Textile Wastewater: An Applied Review of Methods, Technologies, and Costs. [PDF]

open access: yesWater Environ Res
Major textile wastewater treatment technologies, including physicochemical (adsorption, membrane filtration, coagulation–flocculation, advanced oxidation), biological (algal–bacterial systems, fungal treatment, anaerobic digestion, microbial fuel cells), and hybrid approaches.

Chromium-Modified Heterogeneous Bipolar Membrane: Structure, Characteristics, and Practical Application in Electrodialysis

open access: yesMembranes, 2023
The modification of an MB-2 bipolar ion exchange membrane with chromium (III) hydroxide was carried out by a chemical method, namely, by the sequential treatment of the membrane with a solution of chromium (III) salt and alkali.

Bipolar membrane electrodialysis for the alkalinization of ethanolamine salts [PDF]

open access: yesJournal of Membrane Science, 2011
Bipolar membrane electrodialysis for the production of organic bases, in contrast to organic acids, has received little attention in the scientific literature. In the present work we have investigated and compared different membrane configurations for the alkalinization of monoethanolamine salts into the organic base monoethanolamine.
