Abstract

A method for preventing the formation of scale in water flow systems by the removal of scale-related ions from the water, comprising causing a stream of water to flow through the space between a first electrode (23) and a second electrode (26), the first electrode being provided in the form of a curved surface defining an interior space (27) bound by the surface, within which the second electrode is positioned, while concurrently passing an electric current between the electrodes, thereby causing the deposition of solids on the first electrode, arresting the water flow, switching off the electric current or reversing its direction, and causing to rotate, within the space between the first and second electrodes, means for detaching the solids (38) deposited on the first electrode.
