PROBLEM TO BE SOLVED: To provide a ballast water processing device which can resolve clogging of a filter element.SOLUTION: In a ballast water processing device, a filter 2 which filters ballast water is disposed in a casing 1. The ballast water processing device includes a connection passage connecting an external part of the casing 1. An opening part 4a formed at a casing 1 interior side end part of the connection passage is located close to the filter 2 or contacts with the filter 2, and an area of the opening part 4a is configured to be smaller than a filter area of the filter 2. The ballast water processing device further includes: a chemical solution flow passage 51 which connects the connection passage with the other side of a primary side of the filter 2 or a secondary side of the filter 2 and allows the ballast water including a chemical solution for removing foreign objects to circulate therein; and control means which forms a chemical solution circulation passage 50 including the filter 2, the connection passage, and the chemical solution flow passage 51 and circulates the ballast water including the chemical solution by a pump 52.SELECTED DRAWING: Figure 1

    【課題】フィルタエレメントの閉塞を解消できるバラスト水処理装置の提供。【解決手段】バラスト水を濾過処理するフィルタ2をケーシング1内に配置したバラスト水処理装置であって、ケーシング1外部を接続する接続路と、前記接続路のケーシング1内部側の端部に形成される開口部4aはフィルタ2に近接するか又はフィルタ2と接触しており、開口部4aの面積は、フィルタ2の濾過面積よりも小さくなるよう構成され、前記接続路とフィルタ2の一次側及びフィルタ2の二次側の何れか他方を接続し且つ異物を除去するための薬液を含むバラスト水を流通させる薬液流通路51と、フィルタ2、前記接続路及び薬液流通路51を含む薬液循環路50を形成してポンプ52により前記薬液を含むバラスト水を循環させる制御手段と、をさらに備える、バラスト水処理装置。【選択図】図1
