<p>In a method and apparatus for treating fluid flowing through piping so as to prevent the deposition of a calcium and magnesium scale on the piping, for example, positive and negative electrodes of electrically conductive materials having different electrochemical potentials are provided on the outer peripheral surface of an electrically insulative tubular member through which the fluid flows. Because the electrodes are disposed out of physical contact with the flowing fluid, the electrodes do not pose an obstacle to the fluid flow nor are the electrodes abraded or worn by particles that may be entrained in the fluid. Nonetheless, an electroconductive connection between the electrodes is established through the body of fluid by a capacitive effect so that the fluid is ionized. <IMAGE></p> |
