BALLAST WATER TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a ballast water treatment apparatus capable of reducing the consumption of ozone by effective mechanical sterilization using jet streams and cavitation. SOLUTION: A jet stream producing means comprises a jet stream generation means having a water jet nozzle for forming jet streams of ballast water and an impact plate which receives the impact of the jet streams to cause cavitation in a main treatment line for supplying ballast water to a ballast tank 2, wherein an ozone supply part 14 is arranged ahead of or behind the jet stream generation means.
