UV-system is a reliable and comfortable way to sterilise potable water onboard ships. Sterilisation of potable water by UV radiation is a safe and reliable alternative to other methods. The radiation causes photochemical reactions in the cells of micro-organisms, thus killing up to 99,9% of the bacteria and viruses.

The sterilization system is used only for potable water disinfection. To provide qualitative UV-treatment the water must be cleared up from pollition.
