Ballast Water Management System (BWMS) is a system designed to remove and destroy biological organisms (bacteria, algae). The system is still an evolving technology with a growing number of manufacturers, meaning that there is limited inservice experience for these kind of systems being offered and no single system is suitable for all types of ships. Most Ballast Water Management Systems are using the same approach which contains two basic approaches, the Ultra-Violet (UV) and Electro-Chlorination (EC). The transport of ballast water in the overseas traffic is deemed to play a key role when it comes to the transfer of numerous harmful aquatic microorganisms, therefore the release of ballast water at destination ports has been stated as one of the biggest challenges to the environment. The aim of the dissertation is to access the effects of BWMS on the survival of aquatic microorganisms and how the treatment system can stop the spread of invasive species.
