Abstract: Process for the joint production of sodium carbonate and sodium bicarbonate out of sesquicarbonate, in which the sesquicarbonate is dissolved in water, in order to form a feed water solution comprising both sodium carbonate and sodium bicarbonate, in which at least part of the feed water solution is introduced into all the compartments of an electrodialyser and in which a sodium bicarbonate enriched solution and a sodium carbonate enriched solution are extracted from the compartments.

Abstract: An apparatus and the process produces salts by an electrodialysis operation. The basic electrodialysis apparatus is a cell having a number of compartments separated by membranes. A DC source is connected to drive a current through a feed stream passing through the cell which splits the salt stream into an acid and a base. The incoming feed may be nanofiltered to remove divalent metal. The base loop may be in communication with an ion exchange column packed with a material that removes multivalent cations. Depending upon the material being processed and the desired end result either or both the nanofiltration and the ion exchanged column may be used in the apparatus.

Monovalent selctive cation membranes may be used to effect preferential treatment of the monovalent cations to the base loop.
