Ballast water treatment

The eco-environmental stability and biodiversity are in some areas of the world threatened by socalled invasive species. These often cause significant economic losses. In the marine environment, ballast water is seen as the dominant vehicle for transport of invasive species from one eco-system to another. More than 7,000 different species are daily transported in ship’s ballast water and 3-10 bn (billion) cubic meters of ballast water are each year dumped overboard. The financial losses caused by invasive species transported in ballast water are estimated to more than €50bn per year in both the EU and US

When vessels discharge cargo, they take up ballast water to maintain stability and keep the propeller under water for the voyage. When next loading cargo the ballast water is discharged at the destination harbour. Cruise ships, large tankers, and bulk cargo carriers use a tremendous amount of ballast water, which is often taken on-board in the coastal waters in one region after ships unload cargo, and discharged at the next port of call, wherever more cargo is loaded.  Ballast water discharge typically contains a variety of biological materials, including plants, animals, bacteria, and other microorganisms.

These materials often include non-native, exotic species that can cause extensive ecologic and economic damage to the local aquatic ecosystems. Ballast water discharges are believed to be the leading source of invasive species in marine waters, thus posing public health and environmental risks, as well as significant economic cost to industries such as water and power utilities, commercial and recreational fisheries, agriculture, and tourism. To stop this transportation of invasive organisms The International Maritime Organisation (IMO) in 2004 decided on the Ballast Water Management Convention that has now been Ratified making it law for ALL 60,000 ships over 400 tons DWT to fit a Ballast Water Management System (BWMS) between September 8th, 2019 and September 8th, 2024.
