Be ready for new legislation
Since ratification of the IMO Ballast Water Management (BWM) Convention, new-builds need treatment systems installed at delivery. After September 8th 2019, existing vessels will have to retrofit.
Ship owners who need to deballast in United States waters have even more issues to consider.
The decisions you make now are vital to the success of your business for years to come.

Find your system
Your choice of ballast water treatment system needs to be a perfect match for your vessel, ensuring smooth operations and unfailing compliance with environmental legislation. With Alfa Laval PureBallast 3 you can be certain of both.
Select for the long term
Your ballast water treatment system should last – and provide lasting resale value.
Make sure your ballast water treatment system lasts as long as your vessel by choosing key components that won't corrode in seawater conditions.
A UV reactor is a pressure vessel that may need replacing in five years if built with a steel grade like 316L. PureBallast 3 reactors are built with super-austenitic stainless steel, expected to last 20 years or more.
Where the vessel can sail will affect potential buyers, as well as what they are willing to pay. They also value equipment from a recognized supplier who they can count on for long-term support worldwide.

Ballast water treatment legislation
Ballast water treatment regulations are now taking effect. The IMO Ballast Water Management (BWM) Convention has been ratified and U.S. Coast Guard (USCG) legislation is already in force. We have the knowledge and a decade of experience to help you navigate the regulations impacting your vessel.
The USCG Ballast Water Discharge Standard
The USCG Ballast Water Discharge Standard has been in force since June 2012. As of December 2013, all new vessels wishing to deballast in United States waters must comply, with requirements for existing vessels following.
During an initial period, certain IMO-approved systems have been approved for use in United States waters as Alternative Management Systems (AMS). Due to the availability of treatment systems with USCG type approval, IMO systems installed after 7 March 2017 are no longer given AMS approval.
Systems submitted for USCG type approval must currently be tested according to the CMFDA/FDA staining method. The systems must be well developed when testing is performed, and the tests must be conducted by an independent third party. This degree of transparency adds credibility to the test results.
There are more specific requirements on the monitoring of operating parameters during USCG tests.
To date only a handful of ballast water treatment systems have received USCG type approval, including PureBallast 3. Future acceptance of the most probable number (MPN) testing method, which is more appropriate for UV-based systems like PureBallast 3, would possibly allow the continued use of some systems approved as AMS today.
The IMO BWM Convention
Adopted in 2004, the BWM Convention is known officially as the International Convention for the Control and Management of Ship's Ballast Water and Sediments. Though it took many years to ratify, its introduction triggered the development of today's range of treatment systems.
Since its ratification in September 2016, the BWM Convention has made ballast water treatment a major issue worldwide. As of September 2017, newbuilds require type-approved treatment systems, while existing vessels need to have them retrofitted according to the revised IMO implementation schedule. Vessels operating in US waters that have passed their compliance date need to treat the ballast water with a BWMS if discharging in US waters.
Because the BWM Convention was established when less was known about the control mechanisms needed in ballast water treatment, IMO type approval certificates have developed over time. Certificates issued after 2014 offer more detail about the operating limitations of a system, such as salinity, temperature and UV transmittance levels. Any certificate issued before this date should be examined critically and seek the newest revision of a certificate.
Today the BWM Convention is interpreted in a uniform way by third-party testing bodies worldwide, who strive to ensure a high degree of transparency in all testing procedures.
Ballast water treatment legislation
Since the IMO Ballast Water Management (BWM) Convention was ratified, the issue of ballast water treatment legislation has become urgent worldwide, raising questions in the industry.
