Ultraviolet radiation bacteria killing We are using UV lamp now are produce 253.7NM ultraviolet rays. Ultraviolet rays is low energy electromagnetic radiation, it can product priming action. Ultraviolet rays to disinfecting can destroy DNA of virus, bacteria anCd other microorganism, make them lose reproductive ability and then kill them. Ultraviolet rays can sterilize widely with light, it can kill something include: Bacteria, spores, and fungi, including a variety of microorganisms. Ultraviolet rays to disinfecting must choose a correct wave length and also need a full time to disinfecting it. Ultraviolet penetration ability is poor, so must be exposure directly on the surface of the object, so it can kill the bacteria. As the ultraviolet ray can be too clear, transparent water, so can use to disinfecting the water which water provide to the factory. In addition UV sterilization effect is affected by temperature (suitable for 20-40 degrees Celsius), humidity less 60%, suspended solids, organics, and so on. Ultraviolet radiation is harmful to human body, this kind of device is only applicable to no one in using. Ultraviolet rays to disinfecting on the surface of the object have special significance, such as: the surface of table in the food Containers and paper, clothing must be disinfected factory all can use ultraviolet lamp to disinfect. But ultraviolet penetration performance is poor, only can illuminate to kill microorganisms.

UV disinfection technology is one of the attached importance and the fastest developed technology. we both found a lots of companies pushed new type tech and products to the market. The exposure of germicidal ultraviolet is the product of time and intensity. High intensities for a short period and low intensities for a long period are fundamentally equal in lethal action on bacteria. The inverse square law applies to germicidal ultraviolet as it does to light: the killing power decreases as the distance from the lamps increases. The average bacterium will be killed in ten seconds at a distance of six inches from the lamp in an American Ultraviolet Germicidal Fixture.

Germicidal UVC lamps kill up to 99.9% of most viruses, airborne bacteria and mold spores.ultraviolet fixtures from American Ultraviolet have been safely used in homes, as well as in hospitals, laboratories, clean rooms, doctors″ offices, commercial buildings, food processing plants and other commercial and residential environments throughout the world - any place a concern for clean air exists. It emits UVC radiation which deactivates bacteria, viruses and other micro-organisms to prevent them from growing. The module disinfects water and the reservoir walls. It also reduces the presence of unpleasant odors and germs accumulating in your device, therefore requiring less maintenance. Because of its small size, it fits appliances where conventional mercury discharge lamps cannot be integrated, such as refrigerators, coffee machines, air humidifiers, ice makers etc
