Method and apparatus for the purification of water and for the production of solid metal hydroxides by means of electrolysis

摘要

Metal hydroxides may be beaten down in a solid form from an aqueous metal-containing solution by the electrolysis without the addition of reactants, when the electrolysis cell is divided into two compartments. The compartments are separated from each other by a bipolar electrode. In the kathodevak is provided with an opening for the supply of air or oxygen is bubbled along the cathode.
