EFFICACY OF THE SEDNA® - SYSTEM

The SEDNA^®-System has been tested extensively at different locations for several thousands of operating hours. The test sites were selected for their different water quality and challenging water conditions (e.g. high sediment load and / or dense phytoplankton bloom). The evaluation of the biological efficiency was based on the removal / inactivation of the plankton present at the testing sites and on surrogate organisms, respectively. Two different pilot plants were used during the tests, with TRCs of 200 m³/h and 500 m³/h, respectively. All tests were carried out at full scale flow rates.

The SEDNA^®-System demonstrated at each of the test locations, that it reached or even exceeded the D2 standard of the IMO Ballast Water Convention for organisms >50µm and organisms between 10µm and 50µm in the smallest body dimension. The test results were completely independent from the water quality. Neither variations in the salinity, nor excessive suspended solids showed any kind of effect on the efficacy of the treatment process.
