GEA Westfalia Separator Group has received class approval for its ballast water management system, the BallastMaster ultraV 250, from DNV GL.

This approval certifies that the chemical-free system solution for ballast water treatment fulfils all current D-2 standards required by the International Maritime Organization (IMO).

With a performance of up to 250m3/h and a modular design, the BallastMaster ultraV 250 is especially suitable for retrofitting existing ships.

The DNV-GL certified system can be mounted as a complete “plug-and-play” unit as well as a modular, tailor-made unit for new builds or for subsequent installation as well.

It has been designed as a two-stage system which combines a mechanical preliminary filtration system with subsequent disinfection of the ballast water by UV-C and ultrasonic cleaning.

GEO Westfalia said that even given very bad water quality and a very high concentration of organisms and sediment particles, this unit helps ensure a qualitatively consistent disinfection corresponding to IMO guidelines.

During the treatment process, the mechanical-physical system manages completely without the use and generation of environmentally harmful chemicals that have normally have to be disposed of at high cost.

This put together with easy, flexible installation helps provide a low total cost of ownership (TCO), the company said, which is an attractive advantage for both shipyards and shipping companies.
