Legionella Control from Nancrede Engineering
Why is Legionella control so important?
Each year, between 8,000 and 18,000 people are hospitalized with Legionnaires’ disease in the U.S., making it a serious health threat. Legionnaires’ disease can have symptoms like many other forms of pneumonia. Unfortunately, there is currently no vaccine for legionellosis.
Legionnaires’ disease is caused by a type of bacteria called Legionella. The Legionella bacteria are found naturally in the environment, usually in water.

Where do Legionella bacteria grow?Legionella bacteria can grow in water in systems such as:
- Large plumbing systems
- Hot water tanks
- Decorative fountains
- Grocery store misters
- Air conditioners
- Hot tubs
- Cooling towers
- Water softeners

How do you control Legionella?
The key to preventing legionellosis is the maintenance of the water systems in which Legionella grow. Secondary disinfection of water systems in commercial and industrial environments can be very important in that regard.
Consideration should be given to mixed oxidant solutions (MIOX), which have very effective against the build-up of biofouling that forms inside of water system distribution pipelines and that can harbor harmful microorganisms. By eliminating this biofouling, MIOX removes a potential shelter for bacteria in the water supply through its secondary disinfection.
At the same doses and contact times as conventional chlorine, mixed oxidant (MIOX) solution has been shown in numerous laboratory studies to achieve a more thorough and more rapid inactivation of a wider range of microbes, making it an excellent secondary disinfection option.
