ELECTROCHEMICAL PROCESS AND APPARATUS FOR DEOXYGENATION OF WATER OR AQUEOUS SOLUTIONS

摘要

The invention relates to an electrochemical process and an apparatus for a deoxygenation of water or aqueous solutions. In this electrochemical process, the oxygen dissolved in water or an aqueous solution is removed electrochemically in a three-dimensional electrically conductive cathode particle bed of a cell, which bed consists of mechanically wear-resistant particles, which are smaller than 5 mm and which are metal particles or metal, ceramic or polymeric particles coated with a sufficiently thick metal layer, and through which bed the water or the aqueous solution to be treated is led. In the apparatus, by means of which an electrochemical deoxygenation of water or aqueous solutions is performed and which comprises a flow-through cell (1) divided into one or several anode chambers (5) and into one cathode chamber (7) filled with a particle bed (8), the cathode chamber extends in the flow direction of the flow-through cell further than the anode chambers and is filled with an electrically conductive cathode particle bed, which consists of mechanically wear-resistant particles, which are smaller than 5 mm and which are metal particles or metal, ceramic or polymeric particles coated with a sufficiently thick metal layer.
