1. An apparatus for sterilizing water by anodic oxidation comprising:

  • a reactor having at least one anode and at least one cathode, the reactor having a gap of constant width between mutually confronting surfaces of the anode and the cathode, the anode comprising a material that has a greater overvoltage with respect to oxygen generation and with respect to chlorine generation;

    a power supply means connected to the anode and the cathode in series for supplying an electric current between the anode and the cathode;

    a plurality of electrode modules, each electrode module having a plurality of anodes and cathodes alternatively arranged within the module;

    anode spacer elements disposed between each anode, the anode spacer elements contacting a contact surface of each anode to electrically connect the anodes to each other;

    cathode spacer elements disposed between each cathode, the cathode spacer elements contacting a contact surface of each cathode to electrically connect the cathodes to each other; and

    means for pressing the anode and cathode spacer elements together under high pressure to generate a high specific surface pressure at the contact surfaces of the anodes and the cathodes.
