How does UV disinfection work?

Ultraviolet light has a wavelength of 200 – 400 nanometres (nm). UV light is very adaptable and can be used for disinfecting water, deactivating harmful microorganisms in other liquids, treating surfaces, and in disinfection of air. The UVC radiation which is most strong at the wavelength of 254 nm, reaches the microorganisms and physically interacts with their DNA. By changing the DNA the cell division of the microorganism is interrupted – it can no longer split and reproduce and so it loses its pathogenic capabilities. With UV disinfection technology it is possible to destroy more than 99.99% of all pathogens within seconds, without the addition of chemicals such as Chlorine or Bromine, without harmful side effects. Compared to these it is inexpensively, highly efficiently and  very reliable.

How UV disinfection works with liquids?

UV disinfection is a purely physical process. The light necessary for UV disinfection is produced by special UV emitting lamps. A watertight quartz sleeve which allows the UV light to pass through is the barrier between the lamp and the fluid being treated. The liquid to be disinfected runs past the quartz tubing, being irradiated by the UV light. The number of UV lamps that each unit needs changes according to amount, flow rate and transmittance of the water. UVWaterFilter.co.uk systems are ideally suited for the disinfection of drinking water, process water, waste water, salt water, ultrapure water and other translucent fluids, e. g. glucose syrups.
