Abstract
A method and system for purifying liquid is disclosed that includes combining powdered metal particles with the fluid to be treated. The mixture of powdered metal particles or metal and liquid to be treated is then passed through an electrolytic cell. The cell forms multivalent ions which attach to contaminants in the liquid and are subsequently separated out from the liquid using conventional solid/liquid separation techniques. The multivalent ions may also be formed from thin strips of aluminum or formed by pressing layers of powdered metallic particles together and installing in the electrolytic cell between two cathodes, the powdered metal electrode being the anode.
