Abstract
A ballast water treatment device attached to a vessel provided with: a line () through which drawn treatment target water flows; and a ballast tank () connected to a downstream side of the line (). The ballast water treatment device is provided with: a filter () which is disposed in the line () and which filters the treatment target water; and a controller (). The controller () causes the treatment target water to be discharged outboard from an upstream side of the filter () 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 () to filter the treatment target water. Thus, ballast water filtering can be efficiently performed.
