(LUND, Sweden) — The U.S. Coast Guard (USCG) has presented a type-approval certificate for the largest PureBallast 3 reactor size: 1,500 cubic meters per hour (m3/h). Customers can now select any PureBallast 3 system configuration for use in United States waters.
Launched in late 2018, the 1,500 m3/h reactor for PureBallast 3 is optimized for 50 percent more flow than the former largest reactor size. It thus enables a range of more streamlined and cost-efficient system configurations for vessels with large ballast water flows. With USCG type approval in hand as well as IMO revised G8 type approval, those configurations are now available for use worldwide and will remain so even after 28 October 2020.
“Customers have shown great interest in the new possibilities of the 1,500 m3/h reactor for PureBallast 3,” said Peter Sahlen, 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 m3/h with a skid-mounted system up to 6,000 m3/h with dual systems.”
For vessels with ballast water flows of 1,000 m3/h or more, the configurations encompassed by the new USCG type approval offer significant benefits. A 3,000 m3/h system can be achieved with just two reactors, for example, while a 1,500 m3/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,” said Sahlen. “Being able to configure a PureBallast 3 system with even fewer reactors further reduces complexity and cost.”
