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. The bacteria grow best in warm water, like the kind found in large plumbing systems, hot water tanks, large plumbing systems, decorative fountains, and hot tubs (source: Centers for Disease Control and Prevention, cdc.gov). Other common sources of Legionella and Legionnaires’ disease are cooling towers used in industrial cooling water systems, as well as water softeners.

How do you control Legionella?

A proper Water Management Plan paired with secondary disinfection and Legionella Control Water Softeners can help to prevent Legionella from growing in the first place.

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.
