Many municipal wastewater utilities have adopted ultraviolet (UV) disinfection treatment over chemical chlorine disinfection, as UV is safe, environmentally-friendly and cost-effective.From small rural communities to large municipalities, we have effective UV solutions to meet the challenge. Guanyu`s success is evident with over 10,000 municipal UV disinfection facilities treating over 41 billion gallons of water per day – the largest installed base of UV systems in China.


Ultraviolet germicidal irradiation is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.UV Sterilizer is used in a variety of applications, such as food, air, and water purification.UV-C light is weak at the Earth's surface as the ozone layer of the atmosphere blocks it.UV Sterilizer devices can produce strong enough UV-C light in circulating air or water systems to make them inhospitable environments to microorganisms such as bacteria, viruses, molds and other pathogens. UVGI can be coupled with a filtration system to sanitize air and water. The application of UVGI to disinfection has been an accepted practice since the mid-20th century. It has been used primarily in medical sanitation and sterile work facilities. Increasingly it has been employed to sterilize drinking and wastewater, as the holding facilities are enclosed and can be circulated to ensure a higher exposure to the UV. In recent years UVGI has found renewed application in air purifiers.
