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?
Join educators around the world who https://essayclick.net/ are returning to the core values of sharing knowledge freely.
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 absorbs UV energy, which blurs the structure of DNA. The cell is rendered sterile and can no longer reproduce. The cell is now considered dead and no longer a threat.
Why use an ultra-violet water purification system?
UV water purification technology is probably the most cost-effective and most efficient on the market today. It allows homeowners and business owners to remove a range of biological contaminants in their water supply. The UV water treatment offers many advantages over other forms of water treatment for microbiological contaminants. Most importantly, it leaves no chemical in water, it produces no by-product, and it does not change the taste, pH, or other properties of water. Consequently, in addition to producing safe drinking water, it is not harmful to your plumbing and septic system.
The UV treatment is an excellent choice for eliminating biological contamination of most waters. If your home or business requires an additional filtration or if you have a source of private untreated water (rainwater, lake water, wells etc.). The unique objective of UV water treatment system is to kill harmful biological contaminants.
No microorganism can resist to Ultra Violet, unlike the treatment of water with chlorine. The UV is known to be highly effective against bacteria, viruses and algae. In practice, bacteria and viruses are the cause of many diseases carried by waters. Of these viruses, the hepatitis virus and Legionnaires have demonstrated ability to survive for considerable periods to treatment with chlorine, but are easily removed by a UV treatment. For most microorganisms, the effectiveness of UV against microbiological contaminants such as bacteria and viruses generally exceeds 99.99%.
The UV water treatment is very effective (+ 99.99%) against; salmonella (typhoid fever), Salmonella enteritidis (gastroenteritis), vibrio cholerae (cholera) ), mycobacterium tuberculosis (TB), Legionella pneumophila (Legionella), influenza virus, polio, and Hepatitus.
Our corporation’s UV water purifier units contain many germicidal ultraviolet lamps. The Ster-L-Ray germicidal lamp produced by our corporation is a short wave low-pressure mercury vapor tubes that produces ultraviolet wavelengths that are lethal to microorganisms.
