Method of single step electrochemical generation of chlorinated urea, chlorinated dimethylurea and other chlorourea derivatives is disclosed. The chlorinated species are generated in situ and upon demand and can be used for microbial control in industrial water treatment.
The present invention comprises a method for controlling (e.g. inhibiting) or killing microorganisms in an aqueous environment. The method includes the addition of an effective amount of monochlorourea or modified monochlorourea to an aqueous solution. This aqueous solution may be a cooling water system, a recreational water system, a water treatment facility, or any circulating water system (i.e. a papermaking facility). A method of producing monochlorourea or modified monochlorourea is also disclosed.
