Production of organic acid from monovalent acid salt via electrodialysis using a two-compartment electrodialysis unit

A process for the production of an organic acid, the process comprising:

• a) providing a feed stream comprising an aqueous medium of a monovalent salt of an organic acid,
• b) splitting the feed stream into at least a first stream and a second stream,
• c) subjecting the first stream and second stream to a multi-compartment bipolar electrodialysis comprising:
• an acid flow compartment defined by a bipolar membrane and either a cation or anion selective membrane, and
• a base flow compartment defined by a bipolar membrane and either a cation or anion selective membrane,
• wherein the acid and base flow compartments are arranged between a positive electrode and a negative electrode which are separated by either a cation or anion selective membrane,
• whereby the first stream is fed to the acid flow compartment and the second stream is fed to the base flow compartment;
• and
• d) whereafter an aqueous acid stream comprising an organic acid leaves the acid flow compartment and an aqueous base stream comprising a base and monovalent salt of the organic acid leaves the base flow compartment.
