Abstract:
A method for removing or preventing a microbial growth, biofilm, biomass and/or mineral deposit on a hard surface inside an SO 2 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 SO 2 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.
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.
