Wärtsilä’s Aquarius UV ballast water management system (BWMS) has been granted United States Coast Guard (USCG) type approval.
This is the second BWMS by Wärtsilä to receive USCG type approval. The Wärtsilä Aquarius EC (Electro-Chlorination) system was previously granted approval. This technology uses a simple two-stage process involving filtration and electro-chlorination, whereas the Aquarius UV (Ultra-Violet) system uses filtration and UV irradiation and retains its effectiveness regardless of the water quality.
“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,” said Craig Patrick, general manager, sales, Water and Waste, Wärtsilä Marine.
Both technologies have also been awarded type approval by the IMO.
