The technology group Wärtsilä’s Aquarius UV Ballast Water Management System (BWMS) has been granted US Coastguard (USCG) Type Approval. With the company’s other BWMS technology, the Wärtsilä Aquarius EC, already Type Approved by USCG, Wärtsilä becomes the first manufacturer able to offer two USCG Type Approved BWMS technologies.

“Wärtsilä’s dual technology offering provides the broadest range of BWMS solutions for fleet wide regulatory compliance. This means that owners can be sure of having the most appropriate system for their particular needs from the same premium support supplier,” says Craig Patrick, General Manager, Sales, Water and Waste, Wärtsilä Marine.

The Wärtsilä Aquarius UV (Ultra-Violet) technology utilises proven filtration and UV irradiation, while maintaining a high degree of safety and operability. It retains its effectiveness regardless of the water quality.

The Wärtsilä Aquarius EC (Electro-Chlorination) system features a simple two-stage process involving filtration and electro-chlorination across the full scope of a ship’s operating and environmental conditions.

In addition to the USCG approvals, both technologies have also been awarded Type Approval by the International Maritime Organization (IMO). Wärtsilä supports its products, systems, and solutions with the marine industry’s most extensive global service network.
