Chlorine is one of the most widely used disinfectants. It is very applicable and very effective for the deactivation of pathogenic microorganisms. Chlorine can be easily applied, measured and controlled. Is is fairly persistent and relatively cheap. The disinfection mechanism of hydrogen peroxide is based on the release of free oxygen radicals: H2O2 → H2O + O2. UV as a disinfectant has many advantages – UV does not alter taste, odour, colour or pH of the water – UV does not require the addition of chemicals – UV does not impart toxic by-products into the water – UV systems are compact and easy to install – UV systems require very little maintenance.
