  • Process and apparatus for generating haloamine biocide
    Patent number: 8747740
    Abstract: Haloamine biocides are prepared via multi-step processes in an integrated apparatus comprising an electrochemical cell and a mixing chamber, wherein active halogen donor species are electrochemically generated and subsequently reacted with amine-containing compositions to form haloamine biocide. Haloamine biocides prepared according to such processes are used to treat liquids in order to inhibit, reduce, and/or control microorganism growth therein.
    Type: Grant
    Filed: January 25, 2007
    Date of Patent: June 10, 2014
    Assignee: Hercules Incorporated
    Inventors: David E. Sharoyan, Huai N. Cheng, Michael J. Mayer, Freddie L. Singleton
