ABSTRACT:
This invention relates to a process for reducing the population of bacteria in aqueous systems which comprises co-treating said aqueous system with 2,2-dibromo-3-nitrilopropionamide and chlorine dioxide under the conditions specified herein. By co-treating an aqueous system with both 2,2-dibromo-3-nitrilopropionamide and chlorine dioxide, one can achieve a more effective biocidal effect with the same amount of biocide than if either the 2,2-dibromo-3-nitrilopropionamide or chlorine dioxide are used separately.
