Abstract: A ballast water treatment device capable of suppressing damage to a filter is provided. The ballast water treatment device is provided with: a filtering device including a filter for filtering ballast water; a plurality of lines for a flow of the ballast water; a ballast pump for pumping the ballast water to flow into the plurality of lines; and a control unit for controlling the ballast pump to cause the ballast water to flow into a desired line. The plurality of lines includes an object line connected to the filtering device, and a discharge line diverging from the object line and connected to an outside of a system. The control unit controls the ballast pump to discharge the ballast water remaining in the object line to the outside of the system via the discharge line, by causing a ballast water flow through the object line and the discharge line.
