Opis:
The problem of ballast water has been present in the world for the last hundred years, but it has grown and become more complex with the increasing intensity of overseas traffic. Introduction of various species from different parts of the world threatens flora and fauna, especially regarding small and closed seas, such as the Adriatic Sea. New species cause an interruption of the existing food chain which keeps the natural balance and purity of the sea. Many domicile organisms in the sea have been disappearing due to changes in environmental conditions, which significantly impairs the sea-water quality. This paper deals with different possible ways of sea and port protection from ballast water, starting with administrative measures, up to proposals of technologies by which those waters could be treated. The problem of ballast water is of particular concern in the Montenegrin part of the Adriatic Sea, and the protection proposal is given.

Opis:
The fast development of marine transport causes a lot of environmental concerns connected with possible accidents of ships transporting hazardous cargoes as well as oil pollution coming from an exploitation of engine rooms. Moreover, a significant problem is connected with a ballast water handling. The use of ballast water is necessary for the safe movement of large ships. Namely, in maritime transport a ship unloading causes a reduction in its draft - it is a cause of lower steering or even completely prevents the safe movement of the ship. Therefore, in place of the discharged freight the ballast water is collected (often just during the unloading). This water is pumped out from a ship at the site of re-loading. However, this implies the risk of transportation of living organisms over large distances, which (if at the point of discharge of ballast water will find suitable conditions) can become invasive species. Because of the risks involved in carriage of these organisms, the International Maritime Organization (IMO) has developed rigorous standards for permissible amounts of organisms in the discharged ballast water. A number of methods of biological neutralization of ballast water, that meet the requirements of the IMO, have been developed. The topic of this paper is to review currently used methods of neutralization of ballast water. We consider clearing of ballast water from point of view of physics, especially by using electromagnetic radiation and ultrasonic waves.
