Just in time for SMM, the US coast Guard has issued the 10th Ballast Water Management System Type Approval Certificate to Wärtsilä Water Systems. After a detailed review of the manufacturer’s type approval application, the USCG determined the system met the requirements of 46 CFR 162.060.
The treatment principle of the Wärtsilä Aquarius EC BWMS consists of filtration with electrolysis during uptake and neutralisation at discharge. The approval covers models with maximum treatment rated capacities between 250 m3/h and 4,000 m3/h.
A further six systems have applications pending. These are De Nora's balpure, JFE engineering's ballast Ace, Panasia's GloEn Patrol, Headway's OceanGuard. Hyundai's HiBallast and the Enviroceanse In Tank system.
