摘要： A ballast water treatment device including a cylindrical filter (2) that is disposed in a casing (1) and filters and externally discharges ballast water having flowed inside, comprising: a filter rotating unit (3) that rotates the filter (2) around a shaft center of the filter (2); a suction nozzle (4) that is disposed on the primary side of the filter (2) and opens toward the inner circumferential surface of the filter (2); a waste rinsing water discharging unit (5) that externally discharges waste rinsing water sucked by the suction nozzle (4) from the casing (1); a high-pressure fluid jet nozzle (40) that is disposed on the secondary side of the filter (2), opens toward the outer circumferential surface of the filter (2), and jets high-pressure fluid toward the filter (2); and a high-pressure fluid supplying unit (41) that supplies high-pressure fluid to the high-pressure fluid jet nozzle (40). The ballast water treatment device enables rinsing of the filter (2) to be performed efficiently and effectively, and achieves a simple structure and facilitated manufacture and maintenance.

摘要： A ballast water treatment device attached to a vessel provided with: a line (1) through which drawn treatment target water flows; and a ballast tank (5) connected to a downstream side of the line (1). The ballast water treatment device is provided with: a filter (3) which is disposed in the line (1) and which filters the treatment target water; and a controller (7). The controller (7) causes the treatment target water to be discharged outboard from an upstream side of the filter (3) in an early stage of drawing of the treatment target water, until water quality is stabilized, and, when the water quality of treatment target water has stabilized, causes the filter (3) to filter the treatment target water. Thus, ballast water filtering can be efficiently performed.

摘要： A ballast water treatment device includes a ballast water treatment line, a pump for drawing and pressure feeding treatment target water, a filter, a ballast tank for storing filtered water, and an outboard discharger, and the pump, the filter, the ballast tank, and the outboard discharger are provided on the ballast water treatment line. Treatment target water drawn for a predetermined period from start of drawing treatment target water is not caused to pass through the filter but is discharged outboard by the outboard discharger, and discharging outboard by the outboard discharger is stopped at elapse of the predetermined period and treated water having been filtrated by the filter is poured into the ballast tank.

摘要： 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.
