Abstract: A device for electrochemical treatment of a liquid, in particular for sterilising water, is provided with a tubular housing jacket, which is designed as a first electrode body (2) at least on its inner side, a central axial second electrode body (4), a first and second cover part (7, 8), which closes in each case an axial end of the tubular housing jacket, so that an annular gap chamber (6) is formed between the two electrode bodies (2, 4), an inlet channel (9) provided at the first axial end for the liquid, which flows into the annular gap chamber (6), an outlet channel (12) provided at the second axial end for the liquid, which likewise flows into the annular gap chamber (6) and a current supply unit (40), which is electrically connected to the first and second electrode body (2, 4), wherein one electrode body is intended as anode (A) and the other electrode body as cathode (K).

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.
