ABSTRACT: Ballast water released from the cargo ships often acts as an inoculation mechanism for a large number of non-indigenous species that can have an important influence on marine ecosystem’s change and even devastation. The IMO’s “Convention for the Control and Management of Ships’ Ballast Water and Sediments“ demands the establishment of ballast water management system which should solve the question of uncontrolled taking and the operations connected to ballast water releasing. Also, it has been planned to complete the transition to ballast water treatment system. The faculty team work on project which main aim is to examine and develop the principle of technology for ballast water treatment, whose action is based on the use of the combination of filtering technology, hydrocyclone and cavitation.
Until now, the project has proved the possibility of hydrodynamic cavitation appearance inside the hydrocyclone that has been an unexplored phenomenon so far. The next step of the project is to prove hydrodynamic cavitation effectiveness in a joint operation with hydrocyclone which should offer a solution for disabling and removing marine organisms from ballast water.
