Sasaki Shipbuilding purchased two module-mounted BALPURE BP-500 systems for each 12,000 dwt bulk carrier. The system's ballast water treatment energy reaches 500m3 / h. One of the ships has been installed and will be delivered to its operator Daiichi Chuo Kisen Kaisha on October 7, 2011.
The BALPURE system uses electrolytic disinfection technology and was selected by Sasaki for low power consumption, low maintenance requirements and simple operation. This system is superior to the IMO D-2 standard and has no adverse effects on the environment or the ballast tanks of ships.
It is reported that BALPURE's turbulent treatment method, which uses 1% of the total ballast water flow to produce sodium hypochlorite disinfection solution, does not need to be installed in the ballast water main pipeline. BALPURE can be installed in the engine room or any mechanical space that is divided into safety zones. Therefore, this does not take up valuable space in the pump house and does not require expensive equipment to be relocated. The turbulent treatment method can also obtain normal efficiency in a low-salt and low-temperature water environment.
STDN ballast water system first received orders from Japan
On October 18th , Severn Trent De Nora's type-approved BALPURE® ballast water treatment system was selected by Sasaki Shipbuilding for its two new bulk carriers for Toko Kaiun Kaisha, Ltd. at its shipyard in Osaki Kamishima, Japan. The two ships were the first new Japanese ships to install the BALPURE system, which passed the International Maritime Organization (IMO) type approval for ballast water specifications in July.
