UV Disinfection System
The principle of UV disinfection involves using high-energy ultraviolet (UV) photons to damage the DNA and RNA structures of various viruses, bacteria, and pathogens in water. This disruption impairs their ability to produce proteins and reproduce, effectively killing them. UV disinfection is a physical process where UV light directly acts on the genetic material of microorganisms, and it can inactivate known pathogenic microorganisms within 0.1 to 2 seconds.

UV disinfection is one of the spectrum's disinfection technologies and does not introduce any substances into the water, nor does it produce any by-products. It is efficient, environmentally friendly, and safe. After UV disinfection, there is no secondary pollution or by-products, and the treated water can be reused for irrigation in fields or recharged into groundwater, promoting resource recovery.
UV light is divided into three bands: UVA, UVB, and UVC. The UVC band, specifically the wavelength of 253.7 nm, is responsible for the disinfection function. The effectiveness of UV disinfection systems is generally evaluated based on the performance of this wavelength.
