UV Sterilization System 254nm UV Light Water Sterilizer With Electric Automatic Motor Cleaning Device
UV light at certain wavelengths can inactivate microorganisms. UV light with wavelengths from
200-300 nm inactivates most microorganisms, with the greatest amount of inactivation occurring around 260 nm. A low-pressure mercury lamp resembling a fluorescent lamp produces the UV light in the range of 254 nanometers (nm).For UV light, inactivating microorganisms is different than killing them. UV light doesn’t damage or destroy cellular structures like chemical disinfectants do (e.g., chlorine, ozone, chlorine dioxide). Rather, UV light prevents microorganisms from reproducing by damaging their deoxyribonucleic and ribonucleic acids (DNA and RNA). Microorganisms that cannot reproduce cannot infect and are thereby inactivated.
Using UV light in drinking water treatment requires the generation and application of UV light in a way to maximize its effectiveness. All UV drinking water treatment devices require power to generate UV light. When a UV lamp is turned on, mercury in the lamp is “excited” and takes on energy. The mercury quickly discharges that extra energy in the form of UV light.
A UV device used in drinking water treatmenttypically consists of a UV lamp, a clear quartz sleeve to protect the lamp and allow the UV light to penetrate the water, and in some cases a means to measure the intensity of UV light produced.
Water Quality(in)
Water quality plays a major role in the transmission of germicidal UV rays. It is recommended that the water does not exceed following maximum concentration levels.
Maximum Concentration Levels (Very Important)
Total iron content | Less than 0.3ppm(0.3mg/L) |
H2S | Less than 0.05ppm(0.05mg/L) |
Total suspended matter | Less than 10 mg/L |
Manganese content | Less than 0.05 mg/L |
Water hardness | Less than 120 mg/L |
Water Temp. | 5-60Centigrade |
PH value | 6.5-8 |

Application
Ultraviolet water purification systems are used in many applications that includes home/residential(both well water and municipal water supplies), commercial, and industrial. Here is a list of several applications where the power of UV water sterilizers are commonly used to treat and protect the water supply for contaminates such as bacteria and viruses. UV systems applications include private wells, campgrounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, water systems, laboratories, marine, pharmaceutical, dairies and many other applications.
