친환경적 발라스트수 처리를 위한 기반기술 동향분석

Abstract

Ballast water of 10 billion tons is transported throughout the world every year by marine vessels which carry 80% of world trade. Recently, the topic of ballast water has drawn great attention due to its influence on coastal ecosystem, economical damage and human health by harmful nonindigenous organisms included in it. In this connection, IMO(International Maritime Organization) is supposed to restrict the untreated ballast water discharge by mandatory regulations in near future. Hence, an appropriate management system and technology for ballast water are in urgent demand to kill/remove/ inactivate the unwanted organisms in ballast water. In this paper, a comparative review for studies on ballast water is made with aim to stimulate timely development of ballast water treatment technologies, particularly in Korea. At the same time, this paper tries to contribute to domestic development of ballast water treatment technology by presenting the comparison research about existing ballast water treatment technologies. In conclusion, mid-ocean ballast water exchange that is recommended by IMO is introduced with ballast water management method and general ballast treatment technologies.
