Alfa Laval PureBallast passes the ten-year mark as the BWM convention

The announcement that Finland had ratified the IMO Ballast Water Management (BWM) Convention came just days before another milestone: the ten-year anniversary of Alfa Laval PureBallast’s commercial launch.

On 15 September, Alfa Laval marked the passage of ten years since PureBallast was released as the world’s first commercially available ballast water treatment system. At the time of launch in 2006, the global introduction of ballast water treatment requirements had seemed imminent.

Exactly one decade later that milestone has finally been passed. Meanwhile, PureBallast continues to lead. Now in its third generation, PureBallast offers superior performance in fresh and brackish waters as well as marine. Likewise, it is the ideal system for low-clarity water, operating at full flow where UV transmittance is as low as 42%.

“We promised early on that customers would meet ballast water legislation with confidence,” says Anders Lindmark, General Manager, Business Centre PureBallast. “Not only does PureBallast 3.1 fulfil that promise, it does so with previously unthinkable efficiency.”

Alfa Laval ready as the market gains speed

With the ratification process complete, the BWM Convention will enter into force on 8 September 2017. This means the long-anticipated retrofit wave will now begin in earnest, which will put considerable pressure on ballast water treatment suppliers.

“Alfa Laval is well prepared for what’s ahead in terms of both knowledge and capacity,” says Lindmark. “Having sold over 1200 systems and installed more than 300 as retrofits, we have the necessary skills in place and a production infrastructure that is geared for ramp-up.”
