BALLAST WATER TREATMENT SYSTEM AND BALLAST WATER TREATMENT METHOD

摘要

The present invention relates to a ballast water treatment system and a ballast water treatment method. A ballast water treatment system, according to the present invention, comprises: an electrolysis unit for electrolyzing ballast water; a neutralization unit for neutralizing the TRO remaining in the discharged water during a de-ballasting operation; and a control unit for operating the electrolysis unit if an ECU intake valve state signal and an ECU discharge valve state signal are respectively in an ON state and a bypass valve state signal and a de-ballasting discharge valve state are respectively in an OFF state, and operating the neutralization unit if the ECU intake valve state signal and an ECU discharge valve state signal are respectively in an OFF state and the bypass valve state signal and the de-ballasting discharge valve state are respectively in an ON state. Therefore, the ballasting or de-ballasting operation can be carried out by receiving a related signal input even though a ship's crew dos not carry out any additional operating procedures.
