MONOLITHIC SEPARATION MEMBRANE STRUCTURE
PROBLEM TO BE SOLVED: To provide a monolithic separation membrane structure capable of enhancing durability.SOLUTION: A monolithic separation membrane structure 100 comprises a monolithic substrate 10 and porous membranes 20. The monolithic substrate 10 comprises multiple through-holes 24 including a first through-hole 241 adjacent to an inner surface 11S of a first water collection cell Cw through which permeable components flow out. The porous membranes 20 comprise multiple membranes 20 including a first porous membrane 201 formed inside the first through-hole 241. A ratio of a second average thickness t2 at a side opposite to the inner surface 11S of the first water collection cell Cw in the first porous membrane 201 with respect to a first average thickness t1 at the inner surface 11S side of the first water collection cell Cw in the first porous membrane 201, is 0.6 or greater.SELECTED DRAWING: Figure 4
【課題】耐久性を向上可能なモノリス型分離膜構造体を提供する。【解決手段】モノリス型分離膜構造体１００は、モノリス型基材１０と、多孔質膜２０とを備える。モノリス型基材１０は、透過成分が流出する第１集水セルＣｗの内表面１１Ｓに隣接する第１貫通孔２４１を含む複数の貫通孔２４を有する。多孔質膜２０は、第１貫通孔２４１の内側に形成される第１多孔質膜２０１を含む複数の多孔質膜２０を有する。第１多孔質膜２０１のうち第１集水セルＣｗの内表面１１Ｓ側の第１平均厚みｔ１に対する、第１多孔質膜２０１のうち第１集水セルＣｗの内表面１１Ｓと反対側の第２平均厚みｔ２の比は、０．６以上である。【選択図】図４
