What is UV light?
UV (UV) germicidal lamp is a mercury lamp, which emits ultraviolet rays with a short range with a wavelength of approximately 254 nanometers (0.00001 inches). UV (UVC) with a short range breaks molecular bonds in deoxyribonucleic acid (DNA) microorganisms and creates mutations that inhibit growth and reproduction. UV germ light is used to disinfect air and water, cleaning food and sterilizing objects in laboratories and medical environments. The effectiveness of UV gerous light, including microorganism, determines a number of factors, the presence of particles that block UV, fluctuations that can change the wavelength, and the exposure duration. Niels Finsen won the Nobel Prize for Medicine in 1903 for its innovative method of killing bacteria that cause tuberculosis, and in the mid -20th century it became ultraviolet germ light systems.
ultra-short ultraviolet light in UVC lights can damage people, with exposure leading to burning and skin cancer. Eye exposure causesPainful corneal burns, cataracts, retinal toxicity and temporary permanent blindness. UVC generates ozone when it interferes with oxygen molecules, and while ozone in the stratosphere protects Earth from sun radiation, ozone can be toxic when the atmospheric level exceeds 0.05 parts per million. In most germicidal radiation systems, UV germ lamps sit in closed environments such as air circulation or water tank systems, or have defensive shields that alleviate the risk.
Germicidal irradiation using UV germ lamps can be used in conjunction with filter systems for air sterilization in forced air systems, which circulates the air stream in front of the lamp located on the coils or drain pelvis. Water purification UV radiation in waste water treatment has replaced chlorination in humans of the site, but the potential disadvantage of this method of sterilization is that water can be contaminated again after treatmentVinter from chlorinated water. UV germ light is also used to sterilize fresh juices, such as apple cider, and some fruits and vegetables, especially because the regulations were approved in 2001 by the regulations of the United States in 2001, which orders a reduction in bacteria. Microbiological laboratories commonly sterilize glass, glasses, tools, equipment and plastic with ultraviolet light. The lights can also control undesirable pathogens in ponds and aquariums.
Multiple passage through the redundant system increases the efficacy of sterilization by UV germ light by extending the light exposure. UV bulbs should be replaced and routinely cleaned every year to prevent dust and UV particles from lowering. The shielding of light before direct air flow excludes the degradation of the effect by air cooling. Using reflection also amplifies and strengthens the effect of killing pathogen.
