Ballast water is essential for vessel stability, but its improper discharge has caused a significant environmental impact on the oceans.

By transporting water from one port to another, vessels also carry microorganisms, algae and marine species that can establish themselves in new ecosystems, causing a phenomenon known as bioinvasion. This issue has affected biodiversity, the economy and even human health, becoming a global concern for the maritime sector.

Regulations for ballast water control

To reduce the risks of bioinvasion, various regulations have been implemented in recent years. The main one is the International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM), adopted by the International Maritime Organization (IMO) and in force since 2017. This convention requires all ships to implement effective ballast water treatment systems, eliminating potentially invasive organisms before discharge.

Additionally, regional regulations, such as the standards set by the Brazilian National Waterway Transport Agency (ANTAQ) and the United States Coast Guard (USCG), impose specific guidelines for ballast water treatment and discharge in national waters.

Technologies for ballast water treatment

To meet international requirements, vessels must adopt Ballast Water Management Systems (BWMS). These systems use technologies such as:

• Filtration and disinfection – Remove larger organisms and use physical or chemical methods to eliminate microorganisms.
• Ultraviolet (UV) radiation – Inactivates organisms without the need for chemicals.
• Electrochlorination – Generates chlorine onboard for ballast water disinfection.

The choice of technology depends on the type of vessel, route and applicable regulations.
