FILTERING APPARATUS

To provide a filtering apparatus configured so that a filtering structure can be provided inside a settlement tank quickly while securing sealability.SOLUTION: A filtering apparatus 10 comprises a settlement tank 20 in which water to be treated is accumulated and filtering cassettes 50 and 50A, arranged in the settlement tank 20, which filter the water to be treated by upflow. The settlement tank 20 has a pair of receiving beams 29 and 29 hung therebetween, where drainage paths D are formed below the receiving beams 29. The filtration cassette 50 comprises a housing 51, a filtering material 53 and a hanger 55. Support parts are provided in the hanger 55. The plurality of filtering cassettes are arranged parallely inside the settlement tank 20, where a gap between the adjacent filtering cassettes 50 and 50A and gaps between drainage path forming wall parts 41 and the filtration cassettes 50 are sealed with a packing 85 that can be compressed and deformed.SELECTED DRAWING: Figure 4 【課題】沈殿槽内部と濾過構造とシール性を確保しつ迅速に設置することができる濾過装置を提供する。【解決手段】この濾過装置１０は、被処理水が貯留される沈殿槽２０と、沈殿槽２０内に設置され被処理水を上向流で濾過する濾過カセット５０，５０Ａとを備え、沈殿槽２０には一対の受け桁２９,２９が架設され、受け桁２９の下方に排水路Ｄが形成されており、濾過カセットは筐体５１と濾過材５３とハンガー５５とを備え、ハンガー５５には支持部が設けられており、沈殿槽２０の内部には濾過カセットが複数個並列して設置され、隣接する濾過カセット５０，５０Ａどうしの隙間、排水路形成壁部４１と濾過カセット５０との隙間は、圧縮変形可能なパッキン８５を介してシールされている。【選択図】図４
