PROBLEM TO BE SOLVED: To provide a ballast water treatment system and a treatment method of the same which can change the operation number of filters during operation while continuing filtration treatment of treated water.SOLUTION: A ballast water treatment system 101 includes: a pump 6 which pumps and discharges treated water; a treated water flow passage 5 which flows the treated water discharged from the pump 6; a plurality of filters 1a, 1b which are connected in parallel to the treated water flow passage 5; a plurality of control valves 28a, 28b, 29a, 29b which individually control flow rates of the treated water passing through the plurality of filters 1a, 1b respectively; and a control device 110. When the first filter out of the plurality of filters 1a, 1b is maintained in an operation state and the second filter is changed between the operation state and a stop state, the control device 110 changes a target value corresponding to the second filter.SELECTED DRAWING: Figure 1
【課題】被処理水の濾過処理を継続しながら濾過装置の稼働台数を運転中に変化させることが可能なバラスト水処理システム、およびそのような処理方法を提供する。【解決手段】バラスト水処理システム101は、被処理水を汲み上げて吐出するポンプ6と、ポンプ6から吐出された被処理水を流すための被処理水流路5と、被処理水流路5に並列に接続された複数の濾過装置1a,1bと、複数の濾過装置1a,1bの各々を通過する被処理水の流量を個別に制御するための複数の制御弁28a,28b,29a,29bと、制御装置110とを備える。複数の濾過装置1a,1bのうちの第1の濾過装置の状態を稼働状態に保ち、かつ、第2の濾過装置の状態を稼働状態と停止状態との間で変化させる場合には、制御装置110は、第2の濾過装置に対応する目標値を変化させる。【選択図】図1
