  • Method to reduce or prevent scaling
    Patent number: 6258250
    Abstract: A method of reducing scale formation in an aqueous solution using an electrolysis apparatus which has, in an electrolysis chamber, at least two electrodes and a bipolar electrode between the two electrodes includes feeding an aqueous solution to the electrolysis chamber, applying either a DC potential to the two electrodes so that one electrode is an anode and the other electrode is a cathode and reversing the polarity of the electrodes at intervals so that the composition of the aqueous solution remains essentially unchanged, or applying an AC potential to the two electrodes, producing, after the aqueous solution has passed through the electrolysis chamber, a treated aqueous solution having a significantly reduced tendency to form scale.
