Wärtsilä Netherlands: The Wärtsilä Aquarius® Ballast Water Management System (BWMS)

The Wärtsilä Aquarius® Ballast Water Management System (BWMS) range comprises two product series specifically developed to enable customers to meet their global ballast water discharge regulatory obligations. Both technical solutions, one based on filter UV and the other on filter side stream electro-chlorination (EC), have achieved IMO type approval status and both have been AMS accepted by the USCG.

During uptake for both Aquarius® UV & EC, seawater is first passed through a 40 micron back washing screen to remove particulate, sediment, zooplankton and phytoplankton. During discharge this process is by-passed. By virtue of its modular design, each system’s inherent flexibility allows application across the full range of ship types and sizes, for both the new build and retrofit markets.

Wärtsilä offers customers a range of flexible supply options, from the BWMS equipment only, to a full turnkey service covering all phases, from the initial survey through to the supply, installation, and commissioning of the hardware, and continuing with lifecycle after sales service and support.
