Even when it is not directly formed by pathogenic bacteria, biofilm represents the ideal environment for the survival and growth of dangerous microorganisms, such as Legionella pneumophila. In order to prevent such potentially harmful contaminations, it is strictly needed to keep biofilm growth under control, applying cleaning/sanitation treatments as soon as bacteria start to colonize surfaces in contact with the water.

The UK Health and Safety Executive (HSE), in the document "The control of legionella bacteria in hot and cold water systems", indicates that, in order to prevent Legionella outbreaks, dutyholders including employers or those in control of premises should:

  • consider and evaluate monitoring, inspection and maintenance procedures;
  • treat water to either control the growth of microorganisms, including legionella, or limit their ability to grow;
  • monitor any control measures applied.

 

Without a real-time, on line biofilm monitoring system, it is very hard to effectively prevent the risk linked to Legionella and other pathogens.

ALVIM Biofilm Monitoring System helps in keeping track of bacterial settlement and growth inside water lines, tanks, and other surfaces in contact with the water and other liquids allowing to check, at the same time, the efficacy of sanitation treatments. This System has been already used, with positive results, for Legionella prevention in cooling towers and hospitals. An application case in available here.
