    Ultraviolet (UV) disinfection is environmentally safe and recognized as effective for a wide range of pathogens, including viruses.

    UV systems disinfect by inactivating pathogenic microorganisms such as viruses, bacteria and parasites which may be in the water and may cause waterborne disease.

    In the broad light Spectrum, the UV-C wavelength (200-280 nm) has been proven to be the most efficient wavelength to inactivate microorganisms by damaging the nucleic acids (DNA or RNA), which in turns the organism’s ability to reproduce.

    The germicidal effectiveness of a UV system is dependant on various water properties such as UV transmission, flow rate and the applied UV dose, which is a function of the UV intensity delivered by the lamps and the exposure time in the reactor.

    UV systems are used as a final barrier in the drinking water treatment plant to disinfect the water by inactivating (stop growth and reproduction of) the pathogenic microorganisms like viruses, bacteria and parasites. The UV-C lights are particularly efficient for the chlorine resistant microorganisms such as Cryptosporidium and Giardia, even with low dose. So to reduce the risk to be affected by a waterborne diseases, more and more countries are implementing strict limits on these pathogens through new regulations.

    We developed UV products for different markets: Municipal Wastewater, Municipal Drinking Water, and Industries.

  • HOW DOES IT WORK?
    UV-C light is created by a lamp filled with an inert gas and mercury. Electrical energy is applied to electrodes within this lamp which creates an electrical arc through the metallic vapor to generate UV radiation. Two main UV lamp technologies are available for water disinfection. Low pressure lamps have the ability to create a monochromatic radiation at 254 nm, close to the germicidal peak (264 nm). Medium pressure lamps create a broad spectrum of UV wavelengths from 200 to 300+ nm. Degrémont Technologies-Ozonia is able to offer both these powerful technologies.
