Publication number: 20140305881Abstract: Chlorine dioxide generation systems and methods are disclosed. One or more reactants, such as sodium hypochlorite, may be electrolytically generated on-site for delivery to a reaction column. Low concentration reactants may be used to generate chlorine dioxide as part of a mixed oxy-chloro product stream containing free available chlorine. In at least one embodiment, an optical analyzer may be positioned along a reactant feed line to measure a concentration of reactant supplied to a reaction column. A controller may adjust a flow rate of the reactant in response to information provided by the optical analyzer. The controller may also perform pH control within the system. In some embodiments, the chlorine dioxide generator may be incorporated in an all-liquid water disinfection system.Type: ApplicationFiled: June 25, 2014Publication date: October 16, 2014Inventors: Vince G. Alarid, Edward M. Martens, Bobby J. Ownings, Glenn W. Holden

Patent number: 7972532Abstract: A synergistic composition is provided for controlling odor from waste products. The composition comprises a combination of nitrate salt, sulfide-consuming compound, pH-elevating compound, sulfide-oxidizing, nitrate-reducing bacteria, and sulfide-oxidizing enzyme. The method includes adding a sufficient amount of the composition to a waste stream to provide sufficient sulfide-consuming compound to effect immediate removal of sulfide. The composition incorporates a pH elevating compound, which both decreases the amount of gaseous H2S and puts the aqueous phase into a pH range where naturally occurring bacteria can more easily metabolize the sulfide. The composition also includes one or more nitrate salts which will accomplish longer term prevention of odors. Specific bacteria are incorporated into the formulation to insure that the nitrate has the right type and amount of bacteria present to prevent formation of and/or consume sulfide.Type: GrantFiled: May 15, 2009Date of Patent: July 5, 2011Assignee: Siemens Industry, Inc.Inventors: Gregory D. Simpson, Glenn W. Holden
