PROBLEM TO BE SOLVED: To provide a pleat filter that prevents a rupture due to use and contributes to a stable use for a long time and a ballast water treatment apparatus using the same.SOLUTION: A pleat filter, which has folds so that a filter base material may repeat crests and troughs and has a cylindrical shape the axial direction of which is the ridge line direction of the fold, comprises a reinforcement plate in a crest as viewed from inside the cylindrical shape, the reinforcement plate being constituted of a first reinforcement plate located on the rear side of the fold that forms the outer peripheral side salient of the cylindrical shape and a second reinforcement plate located on the gap between adjacent folds that form the inner peripheral side salient of the cylindrical shape with the first reinforcement plate and the second reinforcement plate arranged with a distance in a pleat depth direction of the pleat filter.

    【課題】使用による破断を防止し、長期間安定して使用することに寄与するプリーツフィルター、およびそれを用いたバラスト水処理装置を提供する。【解決手段】フィルター基材が山部と谷部を繰り返すように折り目を有し、前記折り目の稜線方向を軸方向とする筒形状をなすプリーツフィルターであって、前記筒形状の内側から見た谷部に補強板を備え、前記補強板は、前記筒形状の外周側凸部をなす折り目の裏側に位置する第一補強板と、前記筒形状の内周側凸部をなす隣り合う折り目の間隙部に位置する第二補強板とから構成され、前記プリーツフィルターのプリーツ深さ方向において前記第一補強板と前記第二補強板とが離隔を持って配置されているプリーツフィルターとした。【選択図】 図1
