Shipping moves over 80% of the world's commodities and transfers approximately 3 to 5 billion tones of ballast water internationally each year.

There are thousands of marine species that may be carried in ships' ballast water, basically anything that is small enough to pass through a ship's ballast water intake ports and pumps. If these organisms survive transport to other parts of the globe, their impact can be devastating. Such invasions can jeopardize the local ecosystem, and even pose threats to human health. Usually, their effects are irreversible.

The introduction of invasive marine species into new environments by ships' ballast water, attached to ships' hulls and via other vectors has been identified as one of the four greatest threats to the world's oceans. In 2004, IMO adopted the International Convention for the Control and Management of Ships' Ballast Water and Sediments, which will phase in requirements for ballast water treatment over the coming years.

EUT Unit is the core of OceanGuard™ BWMS. Each single unit has the treatment capacity from 100-3000m3/h. The Unit comprises of two parts: Electrocatalysis Unit and Ultrasound Unit. The Electrocatalysis Unit is able to produce large numbers of hydroxyl radicals and other highly active oxidizing substances to kill all organisms in ballast water within several nanoseconds. The whole sterilization process is completed inside the EUT Unit.
