FILTER, WATER PURIFIER, AND WATER PURIFICATION SYSTEM
PROBLEM TO BE SOLVED: To sufficiently wash a hollow fiber membrane in a filter.SOLUTION: The filter 1 comprises a hollow fiber membrane module 3 disposed in a cylindrical container 14 and two or more kinds of granular materials 16 having different specific gravities and stored in the cylindrical container 14. At least light particles 17 having a smaller specific gravity in the granular materials 16 have a diameter of 1.1 times or more and 2 times or less the distance of a point where the distance between a projection of a part of the inner wall of the cylindrical container 14 and the hollow fiber membrane module 3 is maximum.SELECTED DRAWING: Figure 1
【課題】フィルタ内の中空糸膜を十分に洗浄する。【解決手段】フィルタ１は、筒状容器１４内に配置された中空糸膜モジュール３と、筒状容器１４内に格納された、比重の異なる２種類以上の粒状物１６とを備えている。粒状物１６のうち、少なくとも比重の小さい方の軽粒子１７の径が、筒状容器１４の内壁の一部の凸状部と中空糸膜モジュール３との距離が最大となる箇所の距離に対して、１．１倍以上、２倍以下である。【選択図】図１
