The special light sterilizes the water in the ballast water tanks. In the UVC range, a wavelength of 254 nanometers destroys the DNA of the bacteria and pathogens making them inactive, and thus prevents them from reproducing.
For this process, Heraeus develops and manufactures special UV lamps and complete modules and power supplies for integration into modern ballast water treatment systems.
The standards for clean ballast water defined by the IMO, helps stem the introduction of invasive aquatic organisms. With the 2017 ratification of IMO regulations, environmentally compatible treatment systems for ballast water will soon be mandatory on all maritime vessels operating in international waters that discharge ballast water.
