Latest Patents

One of his latest patents is a cost-effective process for detoxification of cyanide-containing effluents. This invention pertains to a method of treating cyanide contained in wastewater with particularly high levels of solids in the stream. The process involves either simultaneous or step-wise dosage of hydrogen peroxide in the form of an aqueous solution of a concentration between 35% to 90% by weight, preferably at least 50% by weight, and SO₂ either in the form of gaseous SO₂ or a solution of sodium and/or potassium sulfite or metabisulfite. This results in the conversion of cyanide ions to non-toxic cyanate ions. Another significant patent is a process for the removal of cyanide from wastewaters. This process is disclosed for the detoxification of effluents containing cyanide by treating them with a mixture of hydrogen peroxide and phosphoric acid.
