Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a filtration device and method having high filtration performance and efficiency, and capable of improving resource saving and economical efficiency.SOLUTION: An objective filtration device is equipped with a filter tank 2 setting plural fabric-made filters 8 stacked separably from each other along the inner wall of a housing tank 7 having the water penetration holes. The magnitude of aspect in the water penetration hole may be 5 to 15 cm. Besides, a filtration method may have a regeneration process of removing the fabric-made filter 8 of at least most inside one among plural pieces-stacked filters 8 to remove the clogging part of the filter 8, and a temporary filtration process of carrying out filtration using other filter 8 except the filter 8 sent to the regeneration process.SELECTED DRAWING: Figure 1
【課題】高い濾過性能及び濾過効率を有し、省資源及び経済性の向上を図ることもできる濾過装置及び濾過方法を提供すること。【解決手段】透水孔を有する収容槽7の内壁に沿って相互に分離可能に複数枚重ねた布製フィルター8を設置してある濾過槽2を具備する。前記透水孔の縦横の大きさは5〜15cmとすることができる。また、複数枚重ねた前記布製フィルター8のうちの少なくとも最も内側にある布製フィルター8を取り外し、該布製フィルター8の目詰まり分を除去する再生工程と、該再生工程に送った布製フィルター8を除いた他の前記布製フィルター8によって濾過を行う臨時濾過工程とを有するようにしてもよい。【選択図】図1 |
