Ultraviolet (UV) light sources, especially UV-C light sources, are widely used in water and air purification systems due to their powerful bactericidal effect. The wavelength range of UV-C light is 200 to 280 nanometers, which can effectively destroy the DNA or RNA of microorganisms, inhibit their replication and reproduction, and thus achieve the purpose of sterilization. Since UV led light sources do not rely on chemicals, they ensure environmental cleanliness while avoiding the production of chemical residues, making them an ideal choice for water and air purification.
Application in water purification
In water purification, UV light sources are mainly used to eliminate microorganisms such as bacteria, viruses, and parasites in water. Traditional water disinfection methods, such as chlorine disinfection, may produce harmful byproducts, while UV light source disinfection does not produce any harmful chemicals. UV water treatment equipment usually exposes sewage to strong ultraviolet radiation through a quartz tube equipped with a UV-C lamp, destroying the genetic material of microorganisms in the water, making them unable to reproduce or survive.
UV water treatment technology has the advantages of simple operation, fast and efficient, and low maintenance cost, so it is widely used in home water purifiers, industrial water treatment, and sewage treatment plants. Especially in areas with poor water quality or lack of clean water sources, UV disinfection technology provides effective guarantee for providing safe drinking water. In addition, UV is also used for secondary disinfection in sewage treatment to ensure that the discharged water meets sanitary standards and prevent water pollution.
Application in air purification
UV light sources play an equally important role in air purification, especially in places such as hospitals, laboratories, and food processing plants that require a highly hygienic environment. UV-C light sources can effectively kill microorganisms such as bacteria, viruses, mold spores, and allergens in the air. UV air purification systems are usually used in conjunction with air filtration systems. After passing through the filter, the air enters the area where the ultraviolet lamp is located and is exposed to the UV light source to kill or inactivate pathogenic microorganisms in the air.
UV air purification technology can effectively eliminate germs and viruses in the air, especially in controlling airborne diseases such as influenza viruses and coronaviruses. Another advantage of UV light sources is that they can effectively fight some pathogens that are resistant to conventional disinfection methods without the use of chemicals or sprays, so they are more friendly to the human body and the environment.
In addition, UV-C lamps are also commonly used in the heating, ventilation and air conditioning (HVAC) systems of buildings to ensure that the air remains clean during circulation, reducing the risk of bacterial and virus transmission and improving indoor air quality.
In the future, with the continuous advancement of UV technology, its application in environmental protection, public health and other fields will be more extensive. Dezhen Light Source will continue to work hard to provide you with higher quality products and better services.
