Successful tests for U.S. Coast Guard type approval with zero holding time

Alfa Laval has successfully completed additional tests at the Norwegian Institute for Water Research (NIVA) to verify the biological efficacy of Alfa Laval PureBallast 3 without holding time.

Alfa Laval has successfully completed additional tests at the Norwegian Institute for Water Research (NIVA) to verify the biological efficacy of Alfa Laval PureBallast 3 without holding time. As a result, PureBallast 3 is on target to be the first UV ballast water treatment system with zero holding time in its U.S. Coast Guard (USCG) type approval for all three water salinities. The test reporting is in its final stages.

NIVA’s ballast team was the first of all international ballast test facilities to run a new testing protocol, established in collaboration with DNV-GL and approved by USCG, for verifying BWMS manufacturer new claim of 0h retention time. As a result, Alfa Laval, being one of the major actors on the ballast market, will probably be the first one to get its BWMS approved by USCG with 0h retention time, says Stephanie Delacroix, Ballast-test Facility Manager at NIVA.
