Can chlorine dioxide be used to disinfect cooling towers?
Chlorine dioxide is used to disinfect the water that flows through cooling towers. It also removes bio films and prevents bio film formation in cooling towers. The removal of bio film prevents damage to and corrosion of equipment and piping and causes the pumping efficiency to be improved. Chlorine dioxide is also effective in removing Legionella bacteria. The circumstances in cooling towers are ideal for the growth of Legionella bacteria. Chlorine dioxide has the advantage that it is effective at a pH between 5 and 10 and that no acids are required to adjust the pH.
