Abstract An electronic water treating device comprising a brass body from which projects a graphite anode and to which is secured a stainless steel canister which functions as a cathode. The device includes an electronic power head connected to an external power supply. A 115 volt AC house current is transformed into two 6.3 volt circuits. The first anode powered circuit receives 6.3 volts which is rectified through a diode bridge and powers the anode through a biased resistance. The second 6.3 volt circuit is rectified through a diode and passes through a condenser and resistance through a transistor and resister to the anode. This latter circuit is a voltage measuring circuit interconnected through a relay to a warning light which is energized and lighted if substantial variation in the current being transmitted occurs. This usually arises when an accumulation of sludge-like calcium carbonate, calcium sulphate and magnesium collects in the canister. This electronic treatment of the flow of water through a pipe conduit system reduces the formation of mineral deposits on water heaters and other devices interconnected in the conduit system in residences and industrial water supply systems. The electronic or electrolysis effect of the direct flow of current from the graphite anode to the stainless steel canister cathode disrupts the collection of calcium and magnesium particles being attracted to the coloids suspended in the water, and in its ultimate effect reduces the formation of scale in the system as well as facilitating the flushing or removal of accumulated deposits in the system.
A water treating device comprising: a body portion having water inlet and outlet aperture means formed therein; an anode removeably secured through electrical insulator means to said body portion; cannister cathode means removeably secured to said body portion such that the interior of said cannister cathode is in fluid communication with said inlet and outlet aperatures and said anode is centrally disposed in said cannister cathode; circuit means electrically connected to said anode and said cannister cathode for providing a flow of direct current through said anode and cannister cathode and through water flowing through said cannister cathode; and a standpipe in fluid communication with said water inlet aperture and projecting away from said body portion adjacent said anode, whereby water entering said cannister cathode is introduced at the base thereof.
