  • Patent number: 10501347
    Abstract: A method of treating water to oxidize organic contaminants comprises heat transfer system includes heating liquid water to a temperature of at least 190° F. at a pressure to keep the heated water in a liquid phase, and contacting the heated water with oxygen and an oxidation catalyst including a noble metal on a porous support comprising a bi-modal pore size distribution including pore sizes from 1 nm to 20 nm and pore sizes from 100 nm to 1000 nm. The resulting catalytic oxidation of the organic contaminants results in the release of gaseous reaction products resulting from the oxidation reaction, which are separated from the treated water in a phase separator to produce a treated water final product.

  • Patent number: 8685257
    Abstract: A method for controlling microbial growth in potable water stored in a vessel having a metallic surface includes heating the metallic surface to a temperature between about 480° C. (900° F.) and about 870° C. (1600° F.), exposing the metallic surface to oxygen during heating to oxidize potential reduction sites on the metallic surface and charging potable water containing silver ions to the vessel. A vessel having a metallic surface is prepared for long-term storage of potable water containing silver ions by heating the metallic surface to a temperature between about 480° C. (900° F.) and about 870° C. (1600° F.) and exposing the metallic surface to oxygen during heating to oxidize electropositive metals on the metallic surface or by treating the metallic surface with an aqueous solution containing on oxidizing agent to oxidize potential reduction sites on the metallic surface.
