Why are bromine systems so popular today for cooling water treatment?
Because many cooling water treatments operate at pH levels above 7.5, bromine has greater biocide effectiveness than any other oxidant. Also, when ammonia is present, the formation of bromamines, which are more active than chloramines, is advantageous. Another advantage in using bromine is that because bromine is heavier, it is not as easily stripped by the air in cooling towers and thus stays in the cooling water longer than chlorine, and with fewer odors. What are the different bromine systems available for cooling water treatment? There are quite a few in use or available today, and the most common are: • Generation of bromine with oxidants such as chlorine compounds by reaction with bromide salt. • Release of bromine from an organic compound when dissolved in water (i.e., bromochlorodimethylhydantoin (BCDMH).brp> • Use of a liquid, stabilized bromine product. Are there other bromine systems in use today? Yes, generation of bromine from a bromide salt is accomplished not only with c
