UV disinfection is physical process that instantly neutralizes microorganisms as they pass through UV lamps submerged in effluent.The process does not add anything to water except UV light and so does not impact on chemical composition or content dissolved oxygen in water. When ultraviolet energy is absorbed by bacteria and viruses, the genetic material (DNA / RNA) is modified so that it can not reproduce. The microorganisms are considered dead and risk of getting a disease is eliminated.
UV disinfection is effective to deactivate most viruses, spores and cysts.
The UV disinfection is a physical process that chemical disinfection, eliminating the need to generate, handle, transport, or store toxic, hazardous or corrosive chemicals.
There is not residual effect that can affect humans or aquatic organism.
The UV disinfection is easy to use for operators.
Disinfection with UV light has a shorter contact time compared with other disinfectants (approximately 20 to 30 seconds with the use of low pressure lamps).
The disinfection with UV light requires less space than other method.
Implementing field this technology is extensive, most common are:
Manufacture of food and drink.
Agricultural and livestock industry.
Labs & cosmetics.
Water treatment for steam generators.
Water treatment for industrial processes.
Distilled water, double distilled and triple distilled.
Water for Injection (WFI).
