13.8 F. U.V. lamp disinfection system.
ULTRAVIOLET LAMP.
Concerns related to pathogenic organisms in the water causing illnesses and
contaminating industrial processes, have led FISAIR S.L.U to provide the optional
integration of ultraviolet technology in its evaporative units. This type of system
eliminates bacteria, viruses and other pathogens, prevents their reproduction, and
results in completely safe drinking water.
U.V. radiation is one band of the electromagnetic spectrum. It has more energy than
visible light. The irradiation of germs present in the water with U.V. light harms their
DNA molecules (figure 1) in a number of ways, which prevents cell division and kills
them. The most harmful radiation for germs has a wavelength of 254 nanometres.
The DNA exposed to this energy can only absorb up to a maximum, after which there
is an irreparable inactivation of the growth of the pathogens.
