How Does It Work?The sun emits invisible light . This natural phenomenon is reproduced inside the chamber of the Delta UV ranges UV systems using powerful lamps, result of leading edge technology, that emit UV-C rays. At 254 nanometers, the optimum wavelenght for destroying micro-organisms (viruses, bacteria, algae, yeasts, mould...), the UV-C penetrate to the heart of DNA (altering the DNA of the microorganisms in a process called thymine dimerization) and disturb the metabolim of cells until thay are totally destroyed. UV is effective at inactivating bacteria, viruses and protozoa such as Cryptosporidium and Giardia.
All germs are thus desactivated (including Legionella, Cryptosporidium and Giardia) and cannot reproduce.
EFFECTIVE DOSE:
The UV chamber in Delta UV ranges are dimensionned according to the pump flow rate, as it is the combination of the contact time in the UV system and the power of the lamp(s) that will ensure that the necessary dose (expressed in milijoules per square centimeter or mJ/cm2) sufficient to eradicate 99.9% of the micro-organisms (bacteria, viruses, algae in suspension...) is received.
