Why Ballast Water Treatment Matters
Every year, ships move millions of tons of ballast water across oceans – and with it, microscopic life that can harm new ecosystems. Effective ballast water treatment is therefore key to prevent the spread of invasive species and protect marine biodiversity worldwide.
The CompactClean Ballast Water Management System (BWMS) from DESMI uses UV light technology to neutralize algae, bacteria, and small organisms before discharge. Being UV based, the CompactClean system does not produce or need hazardous chemicals to work. This ensures that ships meet global environmental standards without introducing harmful chemicals or complex handling procedures.
Compliance and Certification
Ballast water treatment is governed by strict international standards to protect marine environments from invasive species.
Type approved in accordance with the IMO BWMS Code (also referred to as the revised G8), the US Coast Guard (USCG), and multiple classification societies, CompactClean fully complies with the mandatory regulations, ensuring smooth operations in any waters.
DESMI’s CompactClean system has been IMO approved since September 2018 and USCG approved since April 2019, making it a proven, reliable choice for global fleets. With one operating mode worldwide, it eliminates the complexity of switching between regional standards.
