ABSTRACT:
A method and device provide for the deionization and contaminants removal or degradation of aqueous liquids, particularly drinking water. The water is caused to flow in a first direction and while flowing it is treated so as to simultaneously effect deionization via electromigration and degradation or removal of the contaminants therein on particle surfaces. The water flows upwardly through a bed formed by a mixture of conductive and non-conductive particles, such as sand and graphite particles, with the particles of the bed being separated from an anode (mounted on one side of the bed) by an anionic membrane, and a cathode (mounted on the other side of the bed) by a non-ionic porous membrane. According to the invention the following ions and contaminants can be destroyed, or removed from, the water: calcium, magnesium, and other water hardening ions; sodium, iron, bacteria; chlorine, phenol, odor and color contaminants; and pesticides.
