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. The ratio of monohaloamine to dihaloamine is selected to result in a synergistic biocidal effect
