Legionnaires' disease is a type of pneumonia which can cause serious respiratory illness. It can occur when tiny droplets of water (aerosol) containing Legionella bacteria are breathed into the lungs of susceptible people. Preventing Legionnaires' disease is typically achieved by limiting the growth
Most cooling towers are likely to become contaminated with legionella, the bacteria that can cause Legionnaires' disease, at some point in their serviceable life. It is unrealistic to try to prevent entry of the organism into a cooling tower system or to create an environment that entirely precludes
What is Legionnaires' disease? How does it spread? These manmade water sources include whirlpool spas, the cooling towers of large building air conditioning systems, decorative fountains The most important way to prevent Legionnaires' disease is to maintain the water supply properly.
Although Legionnaires' disease primarily affects the lungs, it occasionally can cause infections in wounds and in other Also, home and car air conditioning units don't use water for cooling. How the infection spreads. Outbreaks of Legionnaires' disease are preventable, but prevention

A legionellosis is any disease caused by Legionella, including Legionnaires' disease (a cooling towers, and evaporative condensers of large air conditioning systems, such as [1] During outbreaks, prophylactic antibiotics have been used to prevent Legionnaires' disease in high-risk been cleaned during the summer outbreak, raising concerns about how well the bacteria could be controlled.[52].
While Legionnaires' disease isn't contagious, it can still infect large groups of people if they all share a contaminated water source. This brings up the conundrum of how to kill Legionella without risking a burn every time the hot water is turned on. According to the Occupational Safety and
This not only affects the performance of a cooling tower and water loops; it also endangers human health. However, especially at cooling water microbiological problems can quickly arise due to the optimal temperature level and the suitable nutrient supply: The legionella concentration increases.

Cooling-tower risk. Cooling towers are a major source of the disease, because they provide two things the bacteria need to thrive: a place to grow and a way to enter people's respiratory systems. The huge tanks of warm water in these systems provide an ideal environment for Legionella to thrive.
A fully functioning cooling tower maintenance program ensures detection of problems early on and assures optimum performance during its The Occupational Health and Safety Administration (OSHA) provides several recommendations on how to prevent Legionnaires' disease in cooling towers.
