BALLAST WATER TREATMENT SYSTEM

摘要

According to a ballast water treatment system in one embodiment of the present invention, the quality of a ballast water is monitored, and the operating conditions of a water treatment apparatus are controlled based on the results of the monitoring. By virtue of the above constitution, even when the quality of the ballast water significantly varies depending upon water intake conditions, the ballast water can be treated to always have a constant quality. Further, since water treatment is carried out according to the quality of the ballast water, excess injection of a liquid chemical used in the water treatment and a lack in the amount of the liquid chemical injected can be prevented. For example, when a water treatment apparatus of a sterilization system is used, excess injection of a sterilizing agent and a lack in the amount of the sterilizing agent injected can be prevented, and thus, the application of a load by the sterilizing agent on a coating in the ballast tank and an environment can be prevented.
