Wartsila's Aquarius BWMS granted USCG type approval

(HELSINKI) — Wartsila’s Aquarius EC ballast water management system (BWMS) has been granted type approval by the United States Coast Guard (USCG). This approval verifies that the product has met the specified regulatory, technical, and safety requirements, and represents an endorsement of its design and efficiency principles.

As part of the approval process, the Aquarius EC (electro-chlorination) system’s technology underwent an extensive land and sea test program.

The Aquarius EC is capable of treating ballast water volumes from 250 cubic meters per hour to 4,000 cubic meters per hour. It utilizes a two-stage process comprising both filtration and an electrolysis unit. The resulting neutralization effectiveness is continuously monitored to ensure full compliance with MARPOL discharge regulations.

The Wartsila Aquarius UV system, the company’s alternative technology, has completed all USCG testing requirements, and type approval certification is expected to be granted before the end of this year.
