Ballast treatment system maker Alfa Laval is looking to add to the US type approval it already has for its PureBallast 3 system with the successful conclusion of a new range of tests.

The company has successfully completed additional tests at the Norwegian Institute for Water Research (NIVA) to verify the biological efficacy of 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 USCG type approval for all three water salinities. The test reporting is in its final stages.

“The ability to discharge ballast without holding time in United States waters is an important issue for many customers,” said Peter Sahlén, Manager Research & Development, Alfa Laval PureBallast. “PureBallast 3 was the first ballast water treatment system to be IMO revised G8 ready, and the new test results put it on track to be the first UV system with zero holding time under USCG regulations.”
