Device for treatment of water by sterilization or inactivation under the action of UV radiation emitted by a UV lamp, where UV lamp is a high power mercury lamp or a LED based UV lamp

摘要

The device (100) for treatment of water by sterilization or inactivation under the action of UV rays (12) emitted by a UV lamp, is claimed. The UV radiation is emitted by a high power mercury lamp (11) emitting the UV rays at a wavelength of 250-280 nm and a LED based UV lamp emitting the UV rays at a wavelength of 350-380 nm. The UV lamp delivers a UV spectrum. The device (100) for treatment of water by sterilization or inactivation under the action of UV rays (12) emitted by a UV lamp, is claimed. The UV radiation is emitted by a high power mercury lamp (11) emitting the UV rays at a wavelength of 250-280 nm and a LED based UV lamp emitting the UV rays at a wavelength of 350-380 nm. The UV lamp delivers a UV spectrum whose emission meets the relation X less than Y and 3= Y/X= 15, where X is the peak value of the energy of the spectral emission at a wavelength of 250-280 nm obtained by the UV lamp and Y is the peak value of the energy of the emission spectrum at a wavelength of 350-380 nm emitted by the UV lamp.
