Sažetak
Ships ballast water has been responsible for the translocation of a wide range of marine organisms including some harmful exotic species. Ecological consequences and concerns over effects on human health were reason to start to deal with this problem. The problem has been recognised by the International Maritime Organisation - IMO as one of the international significanse. Since then, there have been found several solutions of the ballast water problem. Despite all efforts, nothing still happens. For adequate treatment of marine organisms initial costs seems to be very high, so shipowners are mostly not convisted to except these costs. Therefore the ballast water treatment solution have to be cheaper but still effective. Ballast treatment plant should not take much of the ships space. Biological criterioums have been determined but technological solution is very hard to find. Authors have tried to find possible sollutions of this problem. Heat treatment and ozone treatments are shown to be very effective. Clor treatment is some less effective but in combination with the filtration or heat treatment can be very good solution since the initial costs are about 10 times smaller than for the ozone treatment. Heat treatment is the best solution but it is facing the termo-energetical optimalisation problem. Ballast water can be treated in land plant or on board of special port ships but such solutions are expensive and hard to provide. Authors believe that the best ballast treatment seems to be on the ship, which carry it. New approach to some of the ballast water treatments (heat, ozone, filtration and Clor) is analysed in this paper.
