Ballast water treatment system.
Around the world more than 10 billion tons (m3/h) of ballast water are carried in ships each year, containing thousands of species of aquatic animals and plants, creating problems for the marine environment and human health, threatening the aquatic flora and economies that depend on healthy aquatic ecosystems.
The international convention for the control and management of ships ballast water and sediments, 2004, mandates that all ships that carry ballast water install a treatment system by the year 2016. The OptiMarin Ballast System is one that meets the stringent requirements put forward in the convention.
The Type Approved Optimarin Ballast System is based on solid separation (filter) 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 treated both during ballasting and de-ballasting to ensure the dual effect.
