By now the use of chlorine dioxide has replaced that of chlorine (hypochlorous acid) in water treatment and disinfection because of the many advantages brought by a biocidal and antiviral power definitely higher as well as independent from pH of the water to treat. Indeed, chlorine dioxide is the safest and the most effective answer against the risk of legionellosis, especially in Hot Water systems, by affecting and breaking down, besides pathogens, even the biofilm, that is the natural habitat in which both Legionella bacteria, the cause of legionellosis, and other species of bacteria proliferate. Using chlorine dioxide in disinfection of water has demonstrated to be no less than 10 times more effective against bacteria, algae, fungi and viruses.

Moreover, chlorine dioxide is not aggressive toward pipes and its effect is longer-lasting, up to several days, and over a wider area from the injection point, ensuring the treatment of a whole plumbing system, even by using a small amount of product. Always unlike chlorine, there is no formation of potentially cancer-causing by-products from disinfection, and for all these reasons use of chlorine dioxide is also ecological and suitable for drinking water treatment. In addition to combating Legionella in hospitals, nursing homes, hotels and schools, other applications for chlorine dioxide disinfection are in food and beverage industries, in waste water treatment, in agriculture, livestock farming and viticulture, and in cooling towers.
