All results are well within the requirements.

The type approved Optimarin Ballast System is based on filtration as pre-treatment and high doses of UV irradiation for inactivation of marine organisms, viruses and bacteria, without affecting the normal operation of the ship. Ballast water is UV treated both during ballasting and de-ballasting to ensure the dual UV effect. Ballast water is only filtered during ballasting.

The OBS is one of very few treatment options that does not use or generate chemicals or biocides in its treatment or cleaning processes. It is based on the idea that such systems should be environmentally sound, simple, flexible and easy to install, and capable of operating on both newbuilds and existing vessels.
