ballast water treatment system to comply
with the stringent IMO Ballast Water
Performance Standard.
The system consists of three treatment
stages:
• Separation of ‘larger’ organisms by

• Supersaturation with nitrogen — and

• Hydrodynamic cavitation by

characteristics
The functional system design and the
treatment unit form a ballast water system
where the tank ventilation is managed by
backpressure controls, leaving the tanks
inert in the dry condition. This eliminates
oxidation of ballast tank coatings and
enhances the effect of the hypoxic water
when the tank is wet.
The whole process takes place while
ballast water is pumped into the ballast
tanks without delay for the ballast handling.
The process restores the level of dissolved
oxygen in the water during discharge.
The electric power will be generated
