Ultraviolet (UV) disinfection is a process used to inactivate microorganisms such as bacteria, viruses, fungi, and protozoa. UV disinfection systems use UV radiation to break down the genetic material of microorganisms, rendering them unable to reproduce and causing them to die. The effectiveness of a UV disinfection system depends on the characteristics of the wastewater, the intensity of UV radiation, and the amount of time that the wastewater is exposed to the radiation. Different types of UV lamps are used for this process, including low-pressure mercury vapor lamps, medium-pressure mercury vapor lamps and UV LEDs.
effectiveness of UV disinfection
UV disinfection is an effective method for inactivating microorganisms such as bacteria, viruses, fungi, and protozoa. UV sterilization works by exposing the microorganisms to ultraviolet radiation, which can be generated by mercury lamps or UV LEDs. The effectiveness of a UV disinfection system depends on:
(1) the characteristics of the wastewater,
(2) the intensity of UV radiation (dose),
(3) and the amount of time.
