On 30 December 2020, the US Coast Guard (USCG) issued its type approval for Alfa Laval PureBallast 2, allowing most owners of Alfa Laval’s second-generation ballast water treatment systems to continue operating in US waters, even when their Alternate Management System (AMS) approval expires.
 
The PureBallast 2 system generation, launched a decade ago, was developed long before the USCG presented its testing regime. As a result, certain technical modifications were needed before PureBallast 2 could undergo USCG testing. With the modifications in place, a PureBallast 2 system with a Boll & Kirsch filter completed the tests in April 2020, and the solution has now received USCG type approval.
 
Owners who wish to take advantage of the USCG type approval will need to make a minor upgrade of their PureBallast 2 systems to meet USCG requirements. After upgrading, PureBallast 2 systems will be approved for operation in both seawater and brackish water.

Peter Sahlén, Head of Alfa Laval PureBallast, said: “With the USCG type approval upgrade for PureBallast 2, we provide yet another way to keep ballast water treatment systems optimised over time.”
