Cooling towers are commonly operated using water at with an alkaline pH to minimize corrosion and, as a result, bromine is frequently seen as the preferred biocide for these waters. Traditional bromine sources are accompanied by operational challenges including handling hazardous chemicals, high operating costs, and complex injection control systems. Recent R&D efforts at De Nora have allowed for the adaption of electrochlorination processes to the production of aqueous bromine, simplifying and decreasing the costs associated with the use of this chemical. This presentation will describe the chemical and electrochemical processes involved and describe how this technology can be deployed into cooling tower water treatment programs.
