How regularly should a cooling tower be chlorinated?

Cooling towers should be chlorinated regularly to prevent bacterial growth, particularly Legionella. Typically, a shock chlorination treatment is recommended every 3 to 6 months, but this can vary based on factors such as water quality and local regulations. Routine maintenance and monitoring should also be conducted to ensure proper sanitation and water treatment. Always consult with a water treatment professional for specific recommendations tailored to your system.
