Prevention of hard water deposits by electrolytic production of calcium carbonate seed crystals on brush-like cathodes. The electrolytic production of calcium carbonate seed crystals that attract lime before it can settle out is known practice. The problem is that the crystals depositing on the cathode inactivate it. The cathode is therefore made of spring quality stainless steel in the form of bristles (22) of a round brush. Surrounding these is the anode (21). The function of fixed rods (10) in the anode/cathode gap is to break off crystals from the cathode wires as they are deformed when they pass over the rods when the cathode assembly is rotated. Alternatively a rotating rod assembly could be used with a fixed cathode. Ultrasound could also be used to dislodge crystals. The electrolysis voltage and the frequency of bending of the cathodes determine the quality of the crystals.
