Ballast water

Updated on 25/02/2019
Définition
Sens commun
Water contained in large tanks that can correct the trim of the boat and its balance. Ballast water is a problem during the emptying of the tank (deballasting) because species living in one part of the world are released into another zone, creating ecological disturbances.

Now, biological and chemical treatment systems must treat these volumes of water to limit the exchange of invasive species.
