An electrochemical cell for treating a fluid comprises a plurality of electrodes 50, 52, 54 comprising solid sheets of electrically conductive diamond material, and a support structure (59, figure 6) for supporting the plurality of electrodes, with a fluid flow path 55 defined between the plurality of electrodes. The plurality of electrodes includes at least a first set of electrodes at a first point along the fluid flow path and at least a second set of electrodes at a second point along the fluid flow path, wherein the second point lies downstream from the first point along the fluid flow path, wherein the first and second set of electrodes have separate electrical connections 56, 58, and wherein the electrical connections for each of the first and second sets of electrodes are configured to periodically switch polarity. This arrangement is therefore stated to be an improvement over the prior art since it comprises an alternating polarity electrode structure, rather than a bipolar electrode structure. The electrodes 50, 52, 54 may include apertures (62, figure 7) through which the fluid to be treated can flow. |
