Systems and processes for removing and purifying bromide from an aqueous bromide solution are described. Electrochemistry is used to either convert bromide to bromine to allow its extraction in an organic phase, or to cause deposition of bromine onto an electrode. In either case, once removed from the aqueous bromide solution, the bromide can be recovered and purified.

Ion-selective separation by shock electrodialysis is performed by applying a voltage differential between electrodes across a porous medium to selectively draw a first species in a liquid toward at least one of the electrodes to a greater degree than a degree to which a second species in the liquid is drawn toward the same electrode. The voltage differential creates a shock in the charged-species concentration in the bulk volume of the liquid within pore channels of the porous medium, wherein the concentration of the first species in a depleted zone of the liquid bulk volume between the shock and the ion-selective boundary is substantially lower than the concentration of the second species in the liquid bulk volume between the shock and the first electrode. A dilute stream including the second species is extracted from the depleted zone separate from a concentrated stream including the first species.

An electrolysis cell and housing provides for simple, toolless cell installation and removal of the electrolysis cell. The electrolysis cell includes an anode and a cathode and requires periodic removal of the electrolysis cell from the housing for cleaning or replacement due to accumulation of deposits on the anode and the cathode. The electrolysis cell includes three push-in fluid connectors and two push-in electrical connections. A filter may be included serially between a water inlet and the electrolysis cell and may include two push-in fluid connectors. A housing rear cover may hold the electrolysis cell and filter in place in the housing and may be removed and reattached to access the electrolysis cell without tools.
