Alfa Laval has announced that it has performed half of the required land-based tests for United States Coast Guard (USCG) approval of its PureBallast 3.1 ballast water treatment system (BWTS).
The tests have been carried out on the chemical-free technology at DHI in Denmark. Following the USCG’s decision not to permit the Most Probable Number (MPN) method as a way of testing, Alfa Laval has switched to the USCG permitted CMFDA/FDA method.
PureBallast 3.1 retains the benefit of being 50% smaller than its predecessors and is therefore specifically suited to ships where space is limited. The system is also highly energy efficient, using 60% less energy than previous versions and handles flows of up to 6000 m3/h.
The remainder of the tests are expected to be concluded within Q2 of 2016.
