As a result, PureBallast 3 is on target to be the first UV ballast water treatment system with zero holding time in its US Coast Guard (USCG) type-approval for all three water salinities.
The test reporting is in its final stages.
Alfa Laval PureBallast’s manager of research and development Peter Sahlén said “The ability to discharge ballast without holding time in United States waters is an important issue for many customers. PureBallast 3 was the first ballast water treatment system to be 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.”
The zero holding time issue is a key factor in the operational cost of ballast water management, a subject that will be discussed at the Asian Tanker Conference this coming February in Singapore.
