Product Introduction

Principles of UV Disinfection

UV radiation of UV Light water filter has three wavelength zones: UV-A, UV-B, and UV-C, and it is this last region, the shortwave UV-C, that has germicidal properties for disinfection. A low-pressure mercury arc lamp resembling a fluorescent lamp produces the UV light in the range of 254 manometers (nm). A nm is one billionth of a meter (10^-9 meter). These lamps contain elemental mercury and an inert gas, such as argon, in a UV-transmitting tube, usually quartz (which, unlike glass, is transparent to UV). Traditionally, most mercury arc UV lamps for UV Light water filter have been the so-called "low pressure" type, because they operate at a relatively low partial pressure of mercury, a low overall vapor pressure (about 2 mbar), a low external temperature (50-100 °C), and low power. These lamps emit nearly monochromatic UV radiation at a wavelength of 254 nm, which is in the optimum range for UV energy absorption by nucleic acids (about 240-280 nm); the UV breaks bonds in the nucleic acids, killing the microorganism.
