Comprehensive treatment concept for Legionella control.
Legionella is a gram-negative bacteria responsible for different types of human diseases. One of this illness is Legionnaires disease, atypical pneumonia which signs and symptoms include a cough, shortness of breath, high fever, muscle pains, and headaches. This often begins two to ten days after being exposed to an aerosol that contains the bacteria. The bacterium is found naturally in fresh water. If this water is not treated correctly before to enter in the industrial systems, bacterias can contaminate hot water tanks and hot tubs. Therefore, Legionella in cooling towers is a well-known and very serious topic.
Untreated and no surveillance systems with biofilm, corrosion and fouling are the perfect environment for the growth of Legionella. Also, warm water, like showers and fountains can be an especially favourable environment for Legionella. For these reasons, it is highly recommended to treat hot water systems. Otherwise, any infection with Legionella will lead to serious damage to your health. Legionella prevention is just as indispensable as a quick and reliable Legionella analysis. Legionella analysis according to ISO 11731 on Legionella spp. is done by cultivating the Legionella on defined nutrient media. The difficulty of detection is due to the presence of accompanying flora in the wastewater.
In addition, Legionella requires 9-10 days longer time to grow in the nutrient medium. In comparison, existing accompanying germs can already form colonies on the nutrient medium in a period of 2-3 days. In order to minimize the disruption of existing accompanying flora, methods for pretreatment are described in ISO 11731 and also in the new UBA recommendation. The effort for the examination laboratories has increased significantly with the new requirements.
