WIPO Patent Application WO/2011/125599
Kind Code:

Abstract:
A filtration device (10) is provided with: a filtration element body (4) formed by spirally winding a sheet-like member; and a filtration tank (1) through which water to be treated is passed and in which the filtration element body (4) is inserted in such a manner that the axis thereof extends in the direction in which the water passes. The sheet-like member is formed by superposing on each other the surface of a mesh sheet (5) having holes through which the water to be treated passes, and the surface of a sheet-like spacer (6) through which the water to be treated is less likely to pass than the mesh sheet (5).
