Danish company creates first ”intank” ballast water treatment

The Danish company Bawat has created a new approach to the treatment of ballast water. Instead of purifying the ballast water when it is on the way to the tank, the water is purified inside the tank. The intank cleaning tanks are now being tested and are expected to be ready when IMO’s convention on the treatment of ballast water takes effect.

CEO of Bawat, Jan Hummer, is on a tight schedule working on a new system for ballast water treatment – the so-called intank system. Yet the schedule will be kept and apparently so will the concept for the purification plant  which can purify ballast water in the tank itself rather than in the pipe system on the way.

“The ballast tank project is evolving exactly as planned. Previously, no one thought it was possible to have the ballast water be cleaned together with the storage itself, but now it is. We expect to do land-based tests during the fall and to have the lake-based tests be done in the first quarter of next year,” says Jan Hummer.
