After completing land-based tests with marine, brackish and fresh water, a test report package for PureBallast has now been finalised by DNV GL. Consequently, Alfa Laval has filed its type approval application with the US Coast Guard (USCG) for the PureBallast 3 family.
Alfa Laval completed all tests of PureBallast during the summer. These were performed using the CMFDA/FDA (staining) method approved by the USCG and were conducted at DHI in Denmark. The testing involved the same hardware, power consumption and flow as the already market-leading IMO-approved version of the PureBallast 3 family.
Type Approval
Alfa Laval has now filed its type approval application, including the CMFDA/FDA test results, with the USCG. Meanwhile, the company continues to support the efforts to validate the Most Probable Number (MPN) method, which the company sees as a preferable alternative to the CMFDA/FDA method for UV treatment systems. The decision to proceed with CMFDA/FDA testing was based on the importance of providing a type-approved solution as quickly as possible.
