  • Method for removal of biofilm
    Patent number: 7407590
    Abstract: The present invention provides a method for the removal of biofilm, flocculent bulked sludge or bulked biologically active sludge from an aqueous system. The method involves adding one or more chlorinated hydantoins, such as dichloro- or monochlorodialkylhydantoin, to the aqueous system. Alternatively, the chlorinated hydantoin may be formed in situ by adding a chlorine source and an alkylated hydantoin separately to the aqueous system. The invention is particularly advantageous because of the outstanding photostability of the chlorinated hydantoin solutions even when exposed to sunlight.

  • Composition including a triamine and a biocide and a method for inhibiting the growth of microorganisms with the same
    Publication number: 20030228373
    Abstract: The present invention is directed to a composition for inhibiting microbial growth, which includes a biocide (other than a triamine) and a triamine. The biocide is an oxidizing biocide, a non-oxidizing biocide, or a combination thereof. This composition is particularly effective at preventing the growth of various microorganisms in aqueous solutions, such as industrial waters. The present invention also relates to a method of controlling the growth of microorganisms in an aqueous composition by adding the composition of the present invention to the solution.
