USCG grants type approval for largest PureBallast 3 reactor

PureBallast 3 reactors

Alfa Laval has gained U.S, Coast Guard ballast water management system type approval for its largest PureBallast 3 reactor size: 1,500 cu.m/h. Customers can now select any PureBallast 3 system configuration for use in United States waters.

The 1,500 cu.m/h reactor was launched last year and is optimized for 50% more flow than the former largest reactor. It thus enables a range of more streamlined and cost-efficient system configurations for vessels with large ballast water flows. With bothUSCG type approval and IMO revised G8 type approval, those configurations are now available for use worldwide and will remain so even after October 28, 2020.

NEW POSSIBILITIES

“Customers have shown great interest in the new possibilities of the 1,500 cu.m/h reactor for PureBallast 3,” says Peter Sahlén, Head of Alfa Laval PureBallast. “Those customers who require USCG type approval can now take advantage of the full range of configurations, which extend from 32 cu.m/h with a skid-mounted system up to 6,000 cu.m/h with dual systems.”

For vessels with ballast water flows of 1,000 cu.m/h or more, the configurations covered by the new USCG type approval offer significant benefits. A 3,000 cu.m/h system can be achieved with just two reactors, for example, while a 1,500 cu.m/h system goes from two reactors to one.

“Today’s UV ballast water treatment systems are already smaller and more cost-effective to install than electrochlorination systems for large flows,” says Sahlén. “Being able to configure a PureBallast 3 system with even fewer reactors further reduces complexity and cost.”
