The Ultra-violet lamps of a water treatment by UV produce UV-C. No UV-C rays from the sun ever come into contact with life on earth, they are completely filtered by the atmosphere. However, man produced UV-C rays do. The UV-C lamps are used in biology laboratory for the effects of germicides. Those UV-C have a radiation with an intensity far greater than the sunlight and are used in the treatment of water to sterilize it.The UV filter can kill most bacteria and viruses in water. However, this type of water treatment does not completely purify water. Indeed, it does not treat the water against chemical pollutants, for example. The installation of systems ultra-violet water purification are therefore combined with other system of water purification, UV light generally has no impact on chlorine, heavy metals and other chemical contaminants.How UV water treatment system works?The water purification by ultra-violet uses a UV light source (lamp), which is enclosed in a transparent protective sleeve (usually quartz). The lamp is mounted in such a way that water passes through the filter by a room flow. The water is then exposed to UV-C rays. When harmful microbes are exposed to UV rays, their nucleic acid… Read full this story
