Wine acidification methods: a review

OENO One, 2023
Global warming is directly linked to a lower concentration in organic acids in grape berries, leading to higher pHs in wine. Because of this lack of acidity, many important factors are impacted, as wine acidity and pH play a crucial role in various ...

Electrodialysis and electrodialysis reversal for the concentration of Li containing solutions

Port-Said Engineering Research Journal
In this paper, the application of electrodialysis reversal (EDR) in the recovery and concentration of lithium chloride and lithium carbonate solutions is described. Both salts are raw materials that can be used for the production of lithium ion batteries. EDR is characterized by a periodical change of electric polarity and hydraulic flows.

Separation of organic acids with electrodialysis

, 2022
S.202-209 : Abb.For the downstream processing in fermentation and enzymatic processes, electrodialysis can be used very efficiently. It is shown that bipolar membrane technique is a very economic way for the separation of organic acids like itaconic acid,

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

Meitan 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 ...

Comparison of anionic membranes used to concentrate nitric acid to beyond the azeotropic mixture

The electrolysis of concentrated nitric acid solutions was carried out in an electrochemical cell with parallel plates (FM01-LC ICI). An anionic membrane that permits the migration of nitrate ions under the influence of an electrical field separated the ...

Co-ion fluxes of simple inorganic ions in electrodialysis metathesis and conventional electrodialysis

, 2015
The main functionality of ion-exchange membranes is to selectively permeate either cations or anions. However, co-ions may permeate as well to some extent through these membranes.

MODELING ELECTRODIALYSIS USING THE MAXWELL-STEFAN DESCRIPTION

, 1995
The Maxwell-Stefan mass transfer description is applied to two electrodialysis systems. Firstly, a model system involving NaCl and HCl is investigated.

A SMALL-SCALE ELECTRODIALYSIS CELL

, 1940
An electrodialysis cell for removing electrolytes from small volumes of colloidal solutions is described. On dialysis of a solution half-saturated with ammonium sulphate, only 2% of the salt remained after three hours.

Ammonium nitrate wastewater treatment by coupled membrane electrolysis and electrodialysis

, 2002
International audienceA process coupling membrane electrolysis and electrodialysis is implemented to treat ammonium nitrate wastewater. Membrane electrolysis produces ammonia and nitric acid while electrodialysis reconcentrates the depleted salt solution.
