Abstract
The technology using the cavitation jet stream in water jet is applied to various fields. In this research, the cavitation jet stream was applied to ballast water processing of a vessel, and the validity to plankton processing was examined. It is found that there is an optimal injection pressure and an injection time for performing plankton processing. Moreover, the low pressure of 2MPa with a round shape nozzle can mostly annihilate planktons.
