92-14: Evaluation of Alternatives to Gaseous Chrlorine for Cooling WaterRecent environmental, safety, and disclosure concerns when gaseous chlorine is used and stored on site for microbiological control have forced many cooling systems to consider alternative oxidative micro biocides. This paper shares field experiences and results in general industrial and process contaminated systems using viable (hypochlorite, bromide, chlorine dioxide) oxidative technologies, providing criteria to determine the best approach for
