Disinfecting water with UV radiation has developed into a widely accepted method in recent years due to its ease of use and efficiency. The wavelength of UV radiation 253.7 nm is also part of the sun's radiation, and it can also be reproduced artificially. UV radiation is much stronger than sunlight - this is why it is suitable for water disinfection. Ultraviolet disinfection is known to destroy legionella, microbes, bacteria, viruses and protozoa in an environmentally friendly way without chemicals. UV disinfection is an ideal method for destroying microorganisms from water and it makes the water drinkable in a bacteriological sense. However, disinfected water cannot be considered fully drinking water quality as such, unless its chemical properties also meet the appropriate standards. It is recommended to examine the quality of household water every three years.
