What is Legionella?

Legionella is a Gram-negative, aerobic bacteria. More than 40 different types with over 60 serogroups are idetinficirana. The disease is caused by Legionella bacteria is associated with Legionella pneumophila serogroup 1. Infections caused by the inhalation of Legionella contaminated water (droplets) or contaminated water sources and so the bacteria enters the lungs instead of the digestive system.

There are two forms of the disease:
a) Legionnarska disease if the infection is not treated mortality is up to 80%., while in the treatment of disease the mortality to 20%
b) Pontiak fever: infection similar to the flu and does not require hospitalization

Legionella is not completely eliminating of the drinking water (because water is not sterilized) during treatment vode.Pri water temperature below 20 ° C bacteria can survive but also to multiply.

Where is it found?

The optimum conditions of development legionella are:

Water temperature between 20 and 50 ° C and a pH value between 5.0 and 8.5. The optimal development of the water temperature between 35 ° C and 45 ° C.Biofilm the pipework.

Legionella live and reproduce in protoza example. Amoeba. Other organisms that live in the biofilm provide important mutrijante for the development of Legionella.

The presence of nutrients, such as calcium, magnesium (lime water), iron, zinc (corrosion products), and organic substances.

Who is exposed to infected?

Tko je izložen zarazi? | osobe s dišnim poteškočama | osobe s oslabljenim imunološkim sustavom

Of legionella disease are exposed to while in the risk group includes:

  • travelers
  • athletes
  • people under stress
  • the elderly
  • people who conzuming cigarettes and alcohol
  • people with respiratory problems (bronchitis, has asthma ..)
  • People with weakened immune systems (HIV, cancer, chronic disease ..)

How to protect yourself?

Prevention is half of health .... Protect yourself and others can only with quality and seriously addressing the problem and prevent a major infestation. The planning, implementation, control, operation and maintenance of the system of drinking water especially in complexes with a large number of users (hotels, motels, apartments, hospitals ...) we can reduce the occurrence of Legionella.

By installing a system for the processing and treatment of water in their facilities, such as anti-fouling preventing limescale and corrosion reduce the occurrence of problems by 99%.

From a range CWG Group we can offer you a wide range of tools and equipment for water treatment:

1. Protection of first entry of particles:
Water filtration is the initial and very important step in preserving health and reducing the cost of maintenance of existing facilities and instalacija.Instalacija filter is essential to prevent the entry of particles of sand, rust and other materials in your system to prevent a favorable background for the development of Legionella

2. Water stones:
Preventing corruption deposition on your ducts, heaters and appliances because scale is one of the biggest "hiding place" bacteria and serves as nursery virus because Legionella need calcium and magnesium as nutrients for its development and razmnozavanje.Instaliranjem water softening device or prevent deposition decrease rapidly and the risk of bacterial growth.

3. Corrosion protection:
Corrosion in water can disrupt the quality of safe water. The development of corrosion in pipeline enables better development of biofilms in pipes, thus providing shelter to colonies of Legionella unhindered development and reprodukcijua. Prevents corrosion can develop dosing of anti-corrosive agents and also reduces the possibility of developing the disease by Legionella bacteria.
