Cooling tower water disinfection must meet demands that differ from those of drinking water disinfection and swimming pool water disinfection. Disinfectants may not affect the system and must remove microorganisms that can affect the system, as well. Cooling tower water is not used as drinking water. As a result, it does not need to meet drinking water quality demands. Work-related exposure to cooling tower water or water vapor may occur. As a result, pathogenic microorganisms in cooling tower water, such as Legionella bacteria, must be deactivated.
