Cooling towers can be a breeding ground for Legionella bacteria, a dangerous microorganism that thrives in watery environments with temperatures between 20°C and 50°C. If left unchecked, Legionella can spread through aerosols produced by cooling towers and cause serious diseases such as Legionellosis.
Legionella thrive in biofilms and deposits that form inside cooling towers, especially if the water treatment system is not optimal. Factors such as poor water circulation, the presence of organic matter, and inadequate disinfectant levels can accelerate the growth of these bacteria. If a person inhales contaminated water droplets, they can develop Legionnaires’ disease, a severe form of pneumonia that can be fatal.
Legionella Impact: More Than Just a Health Concern
The presence of Legionella in cooling towers is not only a health issue, but can also have a major impact on business operations and regulatory compliance. Here are some of the impacts:
1. Public Health Threat
Legionellosis can cause serious lung infections, with a high fatality rate, especially in people with weakened immune systems. Symptoms such as high fever, cough, shortness of breath, and other respiratory complications can develop rapidly.
2. Operational Disruption
If Legionella is detected, the cooling tower may have to be temporarily shut down for cleaning and disinfection, causing disruptions in the operations of factories, office buildings, hospitals, and other public facilities.

3. Regulatory Non-Compliance
Governments and health regulatory agencies have strict standards for Legionella control, such as ASHRAE 188, CDC Guidelines, and WHO Environmental Health Guidelines. Failure to comply with these regulations can result in sanctions, fines, or even lawsuits.
4. Business Reputation is Threatened
Legionellosis outbreaks caused by a company’s cooling tower can have a negative impact on the image and trust of customers, business partners, and the surrounding community. This incident can damage the company’s reputation in the long term.
Legionella Control Solution from Lautan Air Indonesia
Overcoming Legionella problems is not enough with just regular cleaning. It requires a comprehensive water management strategy, regular monitoring, and the application of appropriate water treatment technology. Lautan Air Indonesia presents a comprehensive solution to effectively control Legionella and ensure cooling towers remain safe.
1. Legionella Risk Management Program
We provide risk analysis services to identify potential Legionella growth in your cooling tower, as well as develop mitigation strategies that comply with applicable regulations. This program includes cooling system assessment, identification of vulnerable points, and recommendations for preventive measures.
2. Effective Use of Biocides and Disinfectants
Lautan Air Indonesia offers a wide selection of biocides and disinfectants that have been proven to kill Legionella and prevent its regrowth. We provide chemical treatments based on:
- Oxidatives (such as chlorine, bromine, and peroxides) that work by disrupting the structure of bacteria and biofilms.
- Non-oxidatives (such as isothiazolines and glutaraldehyde) that are more stable under certain conditions and effective in controlling the growth of microorganisms.
3. Digital Monitoring and Control System
With IoT technology, we provide a real-time monitoring system that allows you to detect potential Legionella growth early and take proactive preventive measures. Our sensors and automation systems allow for accurate measurement of water parameters and ensure optimal chemical dosages.
4. Routine Cleaning and Disinfection
Lautan Air Indonesia’s team of experts can perform regular cleaning and disinfection of cooling towers, including mechanical cleaning to remove deposits and biofilms, as well as shock treatment to effectively kill Legionella bacteria. These procedures help maintain water quality and extend the operational life of the cooling system.

5. Optimization of Make-Up and Blowdown Water Quality
The quality of incoming water (make-up water) and discharged water (blowdown) greatly influences the presence of Legionella. We assist in the management of water parameters such as pH, alkalinity, and hardness to maintain optimal conditions, so that the risk of bacterial growth can be minimized.
6. Training and Consulting
Lautan Air Indonesia also provides training for your operational team to better understand how to properly manage Legionella risks and implement best practices in cooling tower maintenance. The training program covers water quality monitoring, disinfection techniques, and the correct use of chemical treatments.
