Abstract
A process for the treatment of hard water to reduce scale formation comprises the production of corrosion by dissolution of graphite or one or more metals, more particllarly iron, zinc or copper, but excluding aluminium, in such a manner that whilst the water remains hard the formation of any passivating film of oxide or metallic salt upon the metallic surfaces, which would stop the corrosion, is prevented, or if such a film is incidentally formed it is immediately removed. The water to be treated may be caused to pass upwardly inside conical receptacles containing metal shavings and grains of sand or carborundum which by their abrasive action prevent formation of a passivating film in the metal. The corrosion may be increased by electric current treatment, by radiation from lamps or from radioaction or fluorescent substances, or by formation of galvanic couples by placing the metal to be corroded into contact with more noble metals or by preliminary immersion of the metal in a solution of a more noble metal. When the water to be treated is non-corrosive or slightly corrosive, corrosive water may be allowed to corrode the metal, the resulting water with corrosive products being then introduced into the water to be treated. Alternatively such water to be treated may be made more corrosive by addition of an acid or a chloride, by bubbling carbon dioxide through the water, by softening part of the water by zeolite filtering material, by removal of oxygen in solution, or by a hot treatment. The prevention of the passivating film may be achieved by adjusting the electric potential or resistance of the metallic surface treated, the potential being measured relatively to a reference calomel electrode in the water adjacent to the metallic surface. In the case of iron brought into contact with water at a pH value of 8, the potential should remain below - .55 volts. Adjustment of the potential or resistance may be done automatically. Specification 25633/11, [Class 46], is referred to.
