Cooling Tower Cleaning

Cooling towers are one of the key components of central cooling systems for buildings of different sizes such as business centers, hospitals, hotels, and industrial facilities. These systems, which are used to meet the cooling water requirement, can harbor many risks that threaten human health due to their working principles. Regular maintenance and cleaning are indispensable to mitigate these risks and ensure that the system operates at high efficiency.

Cooling Tower and Chiller Cleaning

Cooling towers are systems where water comes into contact with air. In this process, particles such as pollen, microorganisms, dust, flies, and health hazardous microorganisms such as Legionella bacteria can accumulate and multiply. In addition, the high dissolved oxygen, polarization, and high pH (8.8-10.5 range) of the water cause corrosion and deposits in the mechanical installation. This not only reduces system efficiency but also poses serious health risks.

Legionella Bacteria and Health Risks

Legionella bacteria is a dangerous microorganism that grows in cooling towers and evaporative condensers, threatening human health. The main systems that provide a suitable environment for the growth of this bacterium are as follows:

• Cooling towers
• Evaporative condensers
• Treatment pools, ornamental pools, fountains
• Domestic water and spray systems
• Sprinklers
• Water tanks located outside the building

In such systems, water must be continuously conditioned with appropriate chemicals and methods to prevent the growth of microorganisms. It is vital to take these risks under control, especially in areas with a high concentration of people such as hospitals, schools, and hotels.

Regular Cleaning of Cooling Towers and Risk Management by Categories

A risk assessment system for cooling towers has been established to protect public health. This system is divided into four different categories according to the area where the towers are located:

• Category 1 (Highest Risk): Close (<200 m) to areas with immunocompromised people, such as hospitals or nursing homes.
• Category 2: Close to a nursing home or a building with a large number of people (>200 m).
• Category 3: Areas adjacent to residential or industrial areas.
• Category 4 (Lowest Risk): Areas isolated from residential areas (>600 m).

According to this classification, cleaning and Legionella monitoring of cooling towers should be done as follows:

• Monthly: Category 1
• Quarterly: Category 2 and 3
• Annually: Category 4

Negative Effects of Corrosion and Accumulation on the System

Corrosion and deposits cause serious problems in the mechanical parts of cooling towers:

• Loss of Efficiency: Deposits cover heat transfer surfaces, reducing energy efficiency.
• Increased Energy Consumption: Dirty systems consume more energy and increase operating costs.
• Shortened Appliance Life: Corrosion causes damage to metal surfaces and shortens the service life of equipment.
