Abstract

Disclosed is a ballast water treatment system including: a ballast water supply unit for supplying seawater employed as ballast water to a ballast water tank; an electrolysis device receiving a part of the seawater being supplied to the ballast water tank, and generating sodium hypochlorite and hydrogen gas as by-product gas by electrolyzing the part of the seawater being supplied to the ballast water tank via the ballast water supply unit; and a hydrogen gas removing device receiving a gas-liquid mixture of electrolyzed water and the hydrogen gas that are generated in the electrolysis device, removing the hydrogen gas by a catalyst reaction, and supplying remaining electrolyzed water to the ballast water tank via the ballast water supply unit.
