Abstract: A biocidal composition comprising 2,2-dibromomalonamide and 2,2-dibromo-3-nitrilopropionamide, and its use for the control of microorganisms in aqueous and water-containing systems.

Abstract: Methods for reducing or inhibiting deposition on or within press felts to increase the effective life of the press felt and reduce or eliminate the need for batch cleaning are disclosed. The methods disclosed treat press felt while paper is being produced with compositions containing at least one enzyme. Additionally, the enzymes can be applied in combination with other non-enzymatic felt conditioning products either by blending and applying at the same application point or by applying the enzyme and the non-enzymatic felt conditioning product at two different locations along the felt. The treatments are applied continuously or intermittently.

Abstract: The present invention describes a method of treating an aqueous system with a hydrodynamic water treatment device in conjunction with polymeric material.

Abstract: The present invention describes a method of treating an aqueous system with a hydrodynamic water treatment device in conjunction with a surfactant.

Abstract: The present invention describes a method of treating an aqueous system with a hydrodynamic water treatment device in conjunction with a biocide.

Abstract: Synergistic mixtures of haloamines and their use to control the growth of microorganisms in aqueous systems are disclosed. The method of using the synergistic mixtures entails adding an effective amount of a monohaloamine and an effective amount of a dihaloamine to an aqueous system.

Abstract: An apparatus and methods to produce synergistic mixtures (or combinations) of haloamines to control growth of microorganisms in aqueous systems are disclosed. The apparatus and methods to produce synergistic mixtures entails producing a batch quantity of a haloamine and converting part of the haloamine to a second haloamine species to form the synergistic mixture.

Abstract: Synergistic mixtures of haloamines and non-oxidizing biocides and their use to control the growth of microorganisms in aqueous systems is provided. The methods entail adding an effective amount of at least one haloamine and at least one non-oxidizing biocide to an aqueous system thereby producing a biocidal synergistic effect.
