The use of UV RADIATION is now recognized as one of the best technologies for disinfecting water. The UV rays to be found in nature are reproduced using special lamps in pure quartz that contain mercury vapours that, when suitably activated by current passing between electrodes, emits photons with varying amounts of energy in the deactivation phase, originating the characteristic UV spectrum. The inactivation of the pathogen microorganisms is due to the damage by this radiation caused to the molecules of the nucleic acids, which is compromised in their cellular replications.

The water’s chemical-physical and organoleptic properties are not altered; the complete absence of by-products of disinfection makes it one of the safest and most commonly used technology for disinfecting water. Depending on their operating conditions, MERCURY VAPOUR LAMPS are able to emit radiation at different wavelengths. If their pressure and temperature are low, they produce the characteristic monochromatic spectrum (UV-C, λ = 253,7 nm) with effective germicide action.
