Production processes of fermented organic acids targeted around membrane operations: design of the concentration step by conventional electrodialysis [PDF]

open access: yes, 2001
Organic acids are increasingly used for various industrial applications. Their production is mainly achieved by fermentation. Precipitation or extraction stages, which generate big amount of effluents, are then traditionally used to get the acid in a ...

Modeling electrodialysis and a photochemical process for their integration in saline wastewater treatment. [PDF]

open access: yes, 2010
Oxidation processes can be used to treat industrial wastewater containing non-biodegradable organic compounds. However, the presence of dissolved salts may inhibit or retard the treatment process. In this study, wastewater desalination by electrodialysis
