The disease<\/a> Legionnaires' disease is an acute disease of the respiratory system caused by infection with bacteria of the genus Legionella<\/a>.method of combating Legionella<\/p>\n

It has mortality that can reach<\/a> up to 15%, while in hospitalized patients it can reach up to 50%. Symptoms appear approximately 3-6 days after exposure.<\/p>\n

What is Legionnaires' disease (Legionella)?<\/h2>\n

The L<\/strong>egionella<\/strong> pneumophila is found in water systems such as lakes, rivers, reservoirs and water supply systems, hot water for use and cooling of large buildings<\/strong>. It can multiply at temperatures between 20\u00b0C and 55\u00b0C. Favorable factors for growth are the presence of rust and mud. Her bacteria Legionella<\/a>It feeds on other bacteria that are also naturally present in the water as well as on what can compose or contain the biofilm that has been created inside the pipes or tanks. Legionella is transmitted through inhalation of water droplets that have been contaminated with the bacteria. The systems reproduced are cooling towers, humidifiers, showers, domestic hot water systems, drinking water networks and large air conditioning systems.<\/p>\n

Apart from the water, which serves the spread of the various species Legionella<\/a>s, other elements that help their spread are the biofilms of algae, which are present in every piping or duct and on the walls of the tanks, as well as the creation of any kind of sedimentary stratification (salts, etc.), which is a focus for the accumulation of the above bacteria. The above leads to network energy losses at a rate of 30%.<\/p>\n

THE Redox<\/strong>Hellas<\/strong> in recent years it has been using an innovative method in the Greek market to prevent and combat the disease by adding it to its water network DUOZON L100<\/strong>, a patented German product based on stabilized chlorine dioxide.<\/p>\n\"shower_b\"\n

The usual methods for combating the various Legionella species have serious drawbacks:<\/p>\n

<\/div>\n

Thermal Shock<\/h3>\n
    \n
  1. High energy costs and consumption of large amounts of water<\/li>\n
  2. Risk of burns during the high heating phase<\/li>\n
  3. Network stress\/Increased pressures in filters and pipes<\/li>\n
  4. Corrosion of metal surfaces<\/li>\n
  5. Formation of deposits and sediments in the pipelines<\/li>\n
  6. Reduction of effectiveness of chemical additives<\/li>\n
  7. Overheating of E\/M equipment<\/li>\n
  8. Consumption of working hours<\/li>\n<\/ol>\n
    <\/div>\n

    Chlorination<\/h3>\n
      \n
    1. Creation of carcinogenic derivatives<\/li>\n
    2. Difficulty keeping chlorine in hot water<\/li>\n
    3. Chlorine is corrosive in high concentrations<\/li>\n
    4. Difficulty dechlorinating, since 20ppm of chlorine is needed to destroy Legionella<\/li>\n
    5. It is a function of pH<\/li>\n
    6. Consumption of working hours<\/li>\n<\/ol>\n

      In all these methods, the algal biofilms, which are responsible for the reappearance of bacteria in the pipes and tank walls, are not destroyed.<\/p>\n

      The company REDOX HELLAS<\/a>, with the use of the disinfectant Duozon L100 offers an effective and at the same time economical solution in the fight against legionella. The action of the disinfectant is based on use stabilized<\/strong> chlorine dioxide.<\/p>\n

      Simple chlorine dioxide has the following disadvantages compared to DUOZON L100:<\/p>\n
