Did you know that UV light is also used at cruise ships?

01.02.2017

Photonics based solutions from ultraviolet to infrared

Large vessels like e.g. containter vessel but also cruise ships need water, so called ballast water to gain stability and balance their mass.

In every port ballast water, which also contains small organisms such as plankton, aquatic invertebrates, fish larvae but also pathogens is loaded into the vessel, travels around the world until it is unloaded again in another port.

In this way, many sea dwellers become stowaways that travel around the world. With intensive UV light these undesired organisms can be killed within the ballast water tanks already on the vessel to minimize their spread.

In future, environmentally compatible treatment systems for ballast water are to become imperative on all maritime vessels, this was defined by the International Maritime Organisation (IMO). One possible method is to treat ballast water with intensive UV light.

The special light disinfects the water. In the UVC range, at a wavelength of 254 nanometres, it destroys the DNA of the bacteria and pathogens, makes them inactive and 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 systems.

Case Story: Mobile measurement of seawater with Heraeus FiberLight® possible


Environmental monitoring ensures that dangerous chemicals in water are controlled and used in accordance with the legal safety regulations. Water analysis is also becoming increasingly important for marine research and the fishing industry.

Special lamps from Heraeus enable water analysis directly on site.
