  • Method of generating aqueous chlorine dioxide
    Patent number: 6645457
    Abstract: A solid-state chlorine dioxide generator for generating an aqueous solution of ClO2 is formed within a block comprising an eductor for establishing a vacuum pressure and a reaction column for producing ClO2 from precursor chemicals. The eductor has a water stream flowing therethrough which establishes a vacuum pressure and draws the ClO2 from the reaction column into the water stream to form an aqueous ClO2 solution. The reaction chamber comprises a novel transition zone of increasing flow area wherein the precursor chemicals thoroughly mix resulting in conversion efficiencies of precursors into ClO2 of 95% and above.
    Type: Grant
    Filed: October 21, 2002
    Date of Patent: November 11, 2003
    Assignee: Sabre Oxidation Technologies, Inc.
