Efficiency of Wärtsilä ballast water management system endorsed with U.S. Coast Guard type approval

The Wärtsilä Aquarius EC Ballast Water Management System

The technology group Wärtsilä’s Aquarius EC Ballast Water Management System (BWMS) has been granted type approval by the U.S. Coastguard authorities. This approval verifies 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, during which it delivered exceptional performance.

“We are naturally delighted that following a stringent review and investigation process, the Coast Guard has granted type approval. This follows similar approval given by the IMO in 2013. Since Wärtsilä offers both EC and UV (ultraviolet) technologies, we are uniquely able to provide impartial advice to owners and operators regarding the most suitable system for their particular needs,” said Timo Koponen, Vice President, Processing Solutions, Wärtsilä Marine Solutions.

The Aquarius EC is capable of treating ballast water volumes from 250 cubic meters/hour to 4,000 cubic meters/hour. It utilizes a simple and efficient two-stage process, comprising both filtration and an electrolysis unit. The resulting neutralization effectiveness is continuously monitored to ensure full compliance with International Convention for the Prevention of Pollution from Ships discharge regulations.

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