In contrast to chemical disinfection methods, UV disinfection is based on a physical process in which microorganisms are killed quickly and effectively. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV radiation, they lose their ability to reproduce and infect. UV radiation has proven to be highly effective against pathogenic organisms, including the causative agents of cholera, polio, typhoid, hepatitis and other bacterial, viral and parasitic diseases. In addition, Trojan uses UV radiation (alone or in combination with
hydrogen peroxide) for so-called UV oxidation, a process that reduces chemical pollutants such as pesticides, industrial solvents and pharmaceuticals.
