Abstract
An electrolytic process and apparatus are disclosed for water purification and pH adjustment. The electrolytic reactor includes an anode, cathode and a bed of particulate ion exchange material modified by converting a portion of the transfer sites to semiconductor junctions. The ion exchange material may be a monobed of either modified anion exchange material or modified cation exchange material, or a mixed bed of both. Undesirable ions are exchanged onto the ion exchange material at the ion exchange sites. Regenerant ions, produced at the semiconductor junctions then exchange with the undesirable ions attached to the ion exchange material, and the undesirable ions migrate through the bed toward the respective anode or cathode and out of the aqueous solution. The pH of the aqueous solution can be adjusted by passing the solution through either a modified cation resin bed or through a modified anion resin bed to lower or increase the pH, respectively.
