Wärtsilä Aquarius® UV BWMS

Wärtsilä AQUARIUS® UV Ballast Water Management System (BWMS) provides robust technology for the treatment of ballast water using a simple two stage process involving filtration and ultra-violet (UV) irradiation, across the full range of ship operating and environmental conditions.

The system uses no active substances, is easy to integrate and maintain, and is type approved according to the IMO Convention and has an Alternative Management System (AMS) acceptance certificate from the USCG. It has also been verified for explosion proof (EX) requirements and can therefore be used on-board hazardous areas.

Wärtsilä works in close cooperation with its customers, our BWMS partnership program covers all stages from fleet evaluation to lifecycle support. Wärtsilä’s tailored turnkey solutions help minimize your environmental footprint, improve operational efficiency and enhance reputation.

      "This partnership with Wärtsilä has allowed Condor to be ready to fit ballast water treatment without the need to lay up any of our ships, since the preparation work, which requires the ship to be out of service, was completed during planned refit periods.”

      Graham Belgum, Fleet Director for Condor.

    • Twister
      The Wärtsilä AQUARIUS® UV Ballast Water Management System (BWMS) was installed onboard the Twister, a Chemgas BV owned LPG carrier.

      For retrofit applications and upgrades, where space availability can be a determining factor, the modular configuration of Wärtsilä’s AQUARIUS® range was a particular advantage and the entire installation process took just 3 weeks.
