Legionella bacteria and pathogenic micro-organisms in fog equipment as I see developer and manufacturer of fog machines fog system type with concern the risk of pathogenic micro-organisms in the water. This can pose a serious threat to the health, but it is far more dangerous, if contaminated water is inhaled through the lungs. Many companies promote their fog systems as the solution for outdoor or indoor cooling. Spraying with water under high pressure produces a fine mist with tiny droplets of water. These droplets have a size of approx. 5-100 microns depending on the pressure and the nozzle type. The effect is based on a simple physical principle, called evaporative cooling. The change of the physical state liquid water is transformed into aerosols by evaporation.
This is bacteria in the water contained in the ambient air. Our immune system works only if we are in good health. This is the first danger for persons who are already weakened due to existing diseases. If we drink water or take a bath, our skin and our gastro-intestinal tract protect us from the most of potentially pathogenic risk factors. But when we breathe contaminated air, get the pathogen at the level of the pulmonary Alveolus directly into the bloodstream. This is the second risk.
Among the most common pathogenic bacteria that may be present in the water: faecal bacteria, fecal Streptococcus, Pseudomonas aeruginosa, Aeromonas hydrophila, Staphylococcus SP., but also viruses. Legionella bacteria, which primarily occur in technical systems, form a very special kind of risks like for example in pipe systems of fog systems (fog system). This type of pathogenic micro-organisms is especially dangerous and can be life-threatening. Legionella bacteria can be found in urban, surface or ground water and spread if the water over time, such z.Bsp boilers, tanks, containers boilers, or in the water supply. They grow best in warm water at 35 to 46 C (95-115 F).
