Tokyo approves ozone BWTS
FineBallast OZ works using a specially-designed pipe to inject micro bubbles of ozone into the ballast water system as ballast water tanks are filled to kill off harmful organisms.
Because the ozone is extracted from the air and generated on board there is no requirement to store the active chemical.
Any remaining harmful substances are eliminated by using activated charcoal before ballast water is discharged, which has no environmental impact.
The system has been approved as complying with IMO Guidelines in the International Convention for the Control and management of Ships’ Ballast Water and Sediments and the procedure for approval of systems making use of active substances.
MES carried out a full scale land-based test of the system to gain the necessary approvals. MOL conducted an onboard test on the operator’s 4,646 teu capacity containership MOL Express.
