Abstract: A method and apparatus for purifying water includes a pump and purification cell, the cell having two electrodes, at least one of which electrodes is approximately 92 percent copper, 3 percent silver and 5 percent nickel, by weight. An electrical potential is developed between the electrodes and caused to alternate in polarity to prevent plating. Copper and silver ions are released into the water at adjustable rate, where they cooperatively destroy bacteria, algae, and the like.
