<p>The present invention provides a method and apparatus for treating electrically conductive fluid. Positive and negative electrodes (1,2) of electrically conductive materials having different electrochemical potentials are spaced apart and electrically isolated from one another so that the only electroconductive connection that develops an electrochemical potential between the electrodes (1,2) is established by fluid to be treated extending between the electrodes. Fluid passing between the electrodes is therefore ionized. Because it has been found that superior effects can be achieved when the fluid is ionized under a voltage only condition, in which there is relatively little current flow through the fluid, an electrical insulator (3) is disposed between the positive and negative electrodes, extending across any shortest direct path therebetween. Thus, the electroconductive connection between the electrodes (1,2), that is established only by the body of fluid to be treated in the apparatus, is established through the fluid along a path that extends around the electrical insulator (3). Such a path, which is longer than any shortest direct path between the electrodes (1,2), defines a relatively long resistive path through the fluid between the electrodes. Accordingly, current flow is inhibited. <IMAGE></p> |
