This presentation will allow you to understand the use of stabilized chlorine in cooling towers.

Traditional chlorination of cooling towers

Chemistry and efficacy of stabilized chlorine

Application of stabilized chlorine

Ellen Meyer

Operation of cooling towers with high cycles of concentration is problematic for use of oxidizing biocides. Particularly with concerns about pathogenic organisms such as Legionella, the importance of microbial control in cooling towers is paramount both for public safety as well as heat transfer efficiency.  Stabilized chlorine has shown advantages in high demand environments where oxidizing biocides may be quickly depleted.  This presentation will discuss the chemistry of stabilized chlorine and its efficacy against microorganisms.  Practical application information will also be provided.
