Apparatus for the sterilization of water
First Claim
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.

Abstract
An apparatus for sterilizing water by anodic oxidation. A reactor contains a plurality of anodes (3) and cathodes (4) arranged as parallel plates within the reactor. The anodes and cathodes are arranged in series within four modules (2). Each module includes two draw bolts (34, 44) extending through bores in the anodes and cathodes and threadably engaged to contact bolts (7) on either side of the module. The contact bolts provide high surface pressure to the anodes and cathodes so that high electrical currents can be conducted through the reactor. The anodes each consist of materials that provide a greater overvoltage with respect to oxygen generation than with respect to chlorine generation. Thus, the reactor can produce a sufficient quantity of oxidants to sterilize the water without adding chlorine compounds to the water.
