Abstract

487,595. Electrolytic treatment of water. FREEBORN, A. G. Nov. 18, 1936. No. 31512. [Class 41] Water is treated to overcome the effects of hardness by using a source of unidirectional current discharge in the water, and a cathode or earth in contact with the water spaced from said source, the electromotive force of the said source being so predetermined that there is a substantially constant potential difference between said source and cathode which is only a small portion of one volt. The source or anode should be so disposed that as much as possible of the water comes into contact with it, and the potential difference should not exceed twelve millivolts. Smooth D.C. or D.C. containing a ripple may be used. Apparatus for carrying out the invention may be inserted in a water main or storage tank, and the cathode generally constitutes a part of a main water system of pipework. An apparatus suitable for use in a water main shown in the Figure, comprises an outer, tubular, earth-connected cathode 1, a tubular anode 5 closed at one end except for an air vent 7, and inlet and outlet extensions 2 and 3, all being insulated one from another. The water enters at 2, passes between anode and cathode, and enters holes 14 in the anode, leaving at 3. Alternatively the anode may have a plurality of narrow slits and part of the outer tube 1 may also be used as an anode by insulation from the rest of the tube 1 and connection by a bridge member to the anode 5. In an apparatus suitable for, a storage tank, the water traverses a circuitous path over a plurality of anode plates in an insulating container placed in the tank, and so arranged that water entering or leaving the tank passes through it ; the plates extend completely across the container with the exception of narrow gaps arranged alternately on opposite sides. The cathode comprises a plate secured in the base or other part of the container. According to the Provisional Specification alternating voltages may be used. Specification 427,766 is referred to.
