  • Anti-microbial agent to control biomass accumulation in SO scrubbers
    Patent number: 11844349
    Abstract: A method for removing or preventing a microbial growth, biofilm, biomass and/or mineral deposit on a hard surface inside an SO2 scrubber is disclosed. In particular, biocide compositions may be dosed in pulse or continuously for the reduction and prevention of biofilms on the hard surfaces inside an SO2 scrubber. A biocide composition disclosed here uses one or more non-oxidizing biocides, especially a mixture of one or more quaternary ammonium compounds and one or more other biocides.
    Type: Grant
    Filed: June 22, 2021
    Date of Patent: December 19, 2023
    Assignee: Ecolab USA Inc.
    Inventors: Junzhong Li, Chris Nagel, Laura Rice
  • METHOD FOR THE RAPID DETECTION OF BACTERIAL SPORES IN AN INDUSTRIAL PROCESS
    Publication number: 20230175035
    Abstract: A method for detecting the presence of bacterial spores is described by measuring microbial metabolic activity over time. Spores are distinguished from vegetative cells and other microorganisms by detecting a burst of metabolic activity indicating germination of spores. This method may be used to detect bacterial spores in a commercial process system, such as a papermaking system within the time frame of a typical work shift.

  • Percutaneous tracheostomy balloon apparatus
    Patent number: 7036510
    Abstract: An apparatus and method for performing a percutaneous tracheostomy procedure utilizing dilatation means that do not require entry into the trachea by downward pressure, in order to minimize the risk of posterior tracheal trauma. In addition, the apparatus is structured to facilitate entry of the tracheostomy tube into the dilated entry site without permitting any significant shrinkage or reduction in diameter of the dilated opening.
