Treatment system for ship ballast water

A ballast water treatment system, which is installed inside a vessel, the treatment system comprising:

• a first feed unit that includes a first tank in which a solid raw material is stored, a water supply device that supplies a first water stream to the first tank, and a first raw material supply device that mixes the solid raw material and the first water stream to generate an aqueous raw material solution;
• a first electrolysis unit that includes a first anode chamber in which a first anode product is obtained by reacting the aqueous raw material solution, a first cathode chamber in which a first cathode product is obtained by reacting water and cations provided from the first anode chamber, and a first diaphragm that separates the first anode chamber and the first cathode chamber;
• a reaction unit in which a treatment agent is obtained by reacting the first anode product and the first cathode product;
• and
• an injection unit that provides the treatment agent to ballast water,
• wherein the reaction unit is integrated with the first electrolysis unit,
• wherein a portion of the inside of the first electrolysis unit is provided as a space in which the first anode product and the first cathode product are collected, and
• wherein the first anode product and the first cathode product react in the space to generate the treatment agent.
