Disinfection using ultraviolet radiation is one of the technologies that are increasingly being used to improve the treatment of drinking and pool water. The principle of disinfection involves the photochemical damage of RNA and DNA, proteins, enzymes, or other biologically significant macromolecules.

The effectiveness of disinfection depends on the dose of UV radiation, the type of UV lamp used, and their arrangement in relation to the flow direction of the drinking or pool water. To correctly select the appropriate type of UV device, it is necessary to determine and guarantee the required dose of UV radiation, which depends on the flow rate and quality of water in terms of its permeability, i.e., the concentration and type of dissolved and undissolved substances that affect the reflection and absorption of UV radiation.

Polychromatic underpressure UV lamps emit UV radiation at 185-400 nm, with the intensity of the emitted UV energy not dependent on temperature and can be operated at various levels depending on the type of UV lamp. The different intensity of emitted UV energy results in the ability to replace up to 12 low-pressure monochromatic UV lamps with one highly efficient UV lamp, which utilizes higher intensity radiation for a shorter period of time. Increased efficiency leads to a reduction in the size and compactness of UV devices.

The combination of UV radiation with other treatment technologies leads to high water quality. The advantages are reduced operational requirements, a reduction in the use of chemicals, and safe and easy operation in automatic mode. The disadvantage is the possibility of secondary contamination, so UV radiation alone is not suitable for hygienic assurance. In practice, it is therefore combined, for example, with chlorination.
