Ballast Water Treatment

Ships when leaving the port empty, take seawater into ballast tanks for stability and to adjust buoyancy. When the ballast water is emptied at a different location, it releases microorganisms into the location, causing environmental pollution and ecological imbalance.

NCL scientists have developed an apparatus which can filtrate and disinfect sea water/ ship’s ballast water. It is based on a mechanical process that kills micro-organisms to the required levels, using hydrodynamic cavitation and rupture of cavities to kill micro-organisms.
They can also be used in making potable drinking water from a contaminated source.
