Though headquartered in Japan, Dowa Line has had operations in the Americas for over 35 years. The company is not only one of the leading Japanese cargo operators in American markets, but also an early mover in ballast water treatment with extensive experience of operating Alfa Laval PureBallast 3.

Alfa Laval PureBallast 3 is type approved by IMO according to the revised G8 guidelines and by the U.S. Coast Guard (USCG).
All generations of Alfa Laval PureBallast, current and previous, have IMO type approval. Alfa Laval PureBallast 3 is type approved according the revised 2016 G8 guidelines, which apply for all systems installed after the entry into force on 28 October 2020. For PureBallast systems installed prior to 28 October 2020, previous type approvals remain valid and no upgrade is necessary.
Today’s Alfa Laval PureBallast 3 is certified for use in all water salinities: fresh, brackish and marine.
USCG type approval
The USCG type approval for PureBallast 3, which allows the discharge of ballast in United States waters, was issued in December 2016. Today’s PureBallast 3 is certified for use in all water salinities: fresh, brackish and marine. The type approval testing was performed using the CMFDA/FDA (staining) method and the same hardware, power consumption and flow as the IMO-approved version of the system.
Most systems of the previous generation, PureBallast 2, can also be upgraded for USCG type approval. In April 2020, USCG tests were completed using a PureBallast 2 system with a Boll & Kirsch filter and minor modifications. The solution was type approved in November 2020 and can operate in both seawater and brackish water.
Both standard and Ex versions of PureBallast have been certified by the major classification societies.
