Treatment against Legionella

Treatment against Legionella:



Legionella is an environmental bacteria which is widely extended in natural aquatic atmospheres, found in small concentrations, without risk to people’s health, and being able to survive in diverse environmental conditions.

If its concentration rises, it means a risk to people, especially when passing into the city’s supply systems. These could be:

  • Human consumption cold water circuits
  • Sanitary hot water
  • Refrigeration towers
  • Evaporative condensers
  • Dehumidifiers
  • Jacuzzi tubs
  • Evaporative conditioners
  • Sprinkler systems
  • Fire protection water supply
  • Ornamental fountains

Which conditions benefit legionella?

Frequently the installations at risk of contracting legionella have amplified systems which collect the necessary conditions for the multiplication of the bacteria:

  • Water temperature between 25 and 45ºC
  • Presence of organic matter
  • Presence of corrosive products and cal incrustations.
  • Stagnant water

These conditions produce the proliferation of bacteria until reaching levels capable of causing illness in people. From these installations, legionella can infect people if such water is sprayed, because the bacteria is transported through the air in micro-drops and inhaled by people.

The transmission is via air, and the risks of getting sick by drinking water contaminated by legionella nor its contamination from person to person haven’t been proved.
