Sewage treatment plants (STPs) from Wärtsilä are the most cost-effective and safe answer for every ship or offshore platform to dispose of wastewater at sea. No tempering with the quality of our oceans.
Wärtsilä sewage treatment units - also known as 'Hamworthy Sewage Treatment Plants' - are certified to meet IMO MEPC 227(64) guidelines. These have been in place for all new-build ships from 1 January 2016 onward.
Each Wärtsilä/Hamworthy sewage treatment unit has been optimised to process all onboard black and grey wastewater streams. The plants are compatible with both conventional gravity and vacuum fed collection systems. On top of that, each STP is fully automatic, allowing for unattended operation. This greatly reduces maintenance requirements and lower long-term operating costs.
Finally, Wärtsilä sewage treatment plants for ships are compact and modular in design, suitable for between-deck installations and adaptable to customer new-build specifications.

SCOPE OF SUPPLY
The Wärtsilä AQUARIUS® UV Ballast Water Management System (BWMS) was installed onboard the Twister, a Chemgas BV owned LPG carrier, as part of the Type Approval process.
The Twister is designed to transport gas and chemical products along shallow rivers. A fast BWMS installation process was therefore essential to reduce the downtime impact on the vessel’s operations. 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.
With the trial period successfully completed, and full compliance with the IMO D2 performance standard had been demonstrated, the Wärtsilä AQUARIUS® was awarded Type Approval in accordance with the requirements of the 2004 IMO Convention for the control and management of ships’ ballast water and sediments. The Wärtsilä AQUARIUS® UV was the first BWMS to have been fully endorsed and type approved by the Flag Administration of the Netherlands.
The vessel is also equipped with the Super Trident Sewage Treatment Plant ST1A, certified to meet IMO MEPC 159(55) guidelines. Optimised for the treatment of black and grey wastewater flows, and suitable for conventional gravity and vacuum fed collection systems, the Wärtsilä Hamworthy Sewage Treatment Plant is controlled automatically. This allows unattended operation, with reduced maintenance requirements and lower long-term operating costs.
