  • Long-term storage of potable water in metallic vessels
    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.

  • Ion exchange reactor
    Patent number: 7857979
    Abstract: An ion exchange apparatus includes at least one fluid passage that extends between an inlet and an outlet for transporting a fluid having ions therein. At least one cartridge includes an ion exchange material and the cartridge has an ion removal rate of removing the ions from the fluid that varies in response to a concentration of the ions in the fluid.
