Ballast water treatment system for ships
AQUATRICOMB™
Aalborg Industries
The Aalborg Industries ballast water treatment
technology is highly efficient, and effectively disinfects water with high organism and sediment concentrations compliant with the standards specified by the IMO BallastWater Convention.
Filtration
The organisms and sediments are removed from the ballast water during the pretreatment phase using filters in order to prevent an accumulation of sediments in the ballast tanks and to guarantee optimal disinfecting. The automatic cleaning action
of the filter modules is brought about by ultrasound (self-cleaning), which lifts organic and inorganic depositions from the filter pipe.
Disinfection
The secondary treatment is performed using the effect of UV-C radiation and ultrasound. Ultrasound guarantees an extremely effective and permanent cleaning of the UV radiators removing biofilms and depositions.
In addition, the ultrasound breaks down particles and microorganisms, thus maximizing the efficiency of the UV treatment. By using monochromatic UV-C radiation (254 nm), organisms and bacteria or phytoplankton are effectively eliminated.
The combination of UV radiation and ultrasound ensures uniform disinfecting according to the D2 standard of the IMO Ballast Water Convention.flue gas flows.
