Sasaki Shipbuilding has bought two skid-mounted BALPURE BP-500 ballast water systems for each of the 12,000dwt bulk carriers it has ordered from Severn Trent De Nora.

Each BALPURE system is capable of treating up to 500m3/h of ballast water .

The company has completed the installation of the systems on one of the two vessels and delivered the vessels to the operator Daiichi Chuo Kisen Kaisha.

The company said the two bulk carriers are the first new Japanese vessels to install the BALPURE system, which received Type Approval to International Maritime Organization regulations for ballast water in July.

BALPURE’s slip stream treatment approach, in which 1% of the total ballast water flow is used to generate the hypochlorite disinfection solution, enables remote mounting away from the main ballast line.
