PROBLEM TO BE SOLVED: To provide a ballast water treatment device for flowing to the secondary side of a filter after filling treated water flowed in a filter in a filter, when starting ballast water treatment operation.SOLUTION: In a ballast water treatment device, a filter 3 for providing a filter 23 in a casing 22 is provided in the middle of a ballast water treatment line 1, and a bypass line 8 for bypassing the filter 3 is connected to the ballast water treatment line 1, and a bypass valve 9 is provided in the bypass line 8, and a treated water valve 12 is provided in the ballast water treatment line 1 on the upstream side of the filter 3, and a treatment water valve 13 is provided in the ballast water treatment line 1 on the downstream side of the filter 3, and when starting water conduction to the ballast water treatment line 1, the bypass valve 9, the treated water valve 12 and a bleeder valve 25 for discharging air in the casing 22, are opened, and are put in a state of closing the treatment water valve 13, and after making a predetermined water quantity flow to the bypass line 8, the treatment water valve 13 is opened, and the bypass valve 9 and the bleeder valve 25 are closed.SELECTED DRAWING: Figure 1

    【課題】 バラスト水処理運転開始時に、濾過機に流入させた被処理水をフィルタ内に満たしてからフィルタの二次側へ流すようにしたバラスト水処理装置を得る。【解決手段】 バラスト水処理ライン1の途中に、ケーシング22内にフィルタ23を設けた濾過機3が備えられ、バラスト水処理ライン1には濾過機3をバイパスするバイパスライン8が接続され、バイパスライン8にバイパス弁9が設けられ、濾過機3の上流側のバラスト水処理ライン1には被処理水弁12が設けられ、濾過機3の下流側のバラスト水処理ライン1には処理水弁13が設けられているバラスト水処理装置であって、バラスト水処理ライン1への通水開始時には、バイパス弁9、被処理水弁12及びケーシング22内の空気を排出するエア抜き弁25を開き、処理水弁13を閉じた状態とし、バイパスライン8に所定の水量を流通させた後に、処理水弁13を開き、バイパス弁9、エア抜き弁25を閉じるようにした。【選択図】 図1
