  • Biocidal blends of quaternary ammonium compounds and chlorine dioxide
    Patent number: 5611938
    Abstract: This invention relates to biocidal blends comprising quaternary ammonium compounds and chlorine dioxide. It also relates to a process of inhibiting the growth of bacteria in aqueous system which comprises adding the biocidal blend to an aqueous system containing bacteria. The use of the biocidal blend results in an unexpected synergism.

  • Process for reducing the population of bacteria in contaminated aqueous systems
    Patent number: 5562835
    Abstract: This invention relates to a process for reducing the population of bacteria in aqueous systems which comprises co-treating said aqueous system with 2,2-dibromo-3-nitrilopropionamide and chlorine dioxide under the conditions specified herein. By co-treating an aqueous system with both 2,2-dibromo-3-nitrilopropionamide and chlorine dioxide, one can achieve a more effective biocidal effect with the same amount of biocide than if either the 2,2-dibromo-3-nitrilopropionamide or chlorine dioxide are used separately.

  • Automated method for controlling the rate of chlorine dioxide generation
    Patent number: 5382520
    Abstract: An automated process for controlling the rate chlorine dioxide made from sodium chlorate-chloride and sulfuric acid is generated. The process automatically adjusts the rate of chlorine dioxide production to the needs of the system treated with chlorine dioxide by controlling the feed of one or more of the reactants by means of a multiple feed-back loop system which provides adequate oxidative treatment while avoiding overfeed or underfeed conditions.

  • Method of treating a spent caustic stream from a sour water stripper to reduce the sulfide content thereof
    Patent number: 5246597
    Abstract: This invention relates to a method of reducing the concentration of sulfides in an aqueous system by first treating the aqueous system with hydrogen peroxide to lower the sulfide concentration to approximately 300 ppm, or less, then subsequently treating the aqueous system with chlorine dioxide to further reduce the sulfide concentration to a desirable level. The method of the invention is capable of reducing the sulfide content of the treated aqueous system to as low as tenths of a part of sulfide per million parts of sour water.
