  • Water treatment apparatus reducing hard water deposits in a conduit
    Patent number: 6689270
    Abstract: Water having dissolved salts therein causing scaling is treated by flowing through a passage in an elongate tubular member. The tubular member has a first metal inside surface exposed to the water. A second metal surface is positioned therein and the two surfaces have areas of 1:1 up to about 125% with the second metal being different from the first metal. The metal surfaces are electrically insulated from each other so that current flow between the two is through the water.
