Abstract: A separation recovery system for separating and recovering an object to be separated includes a metal porous membrane which has a first principal surface and a second principal surface facing the first principal surface and has a plurality of through-holes extending between the first principal surface and the second principal surface, a supply device which supplies a first fluid containing the object to be separated from the first principal surface of the metal porous membrane toward the second principal surface, and a backwash device which supplies a second fluid containing a plurality of particles larger than a size of the plurality of through-holes of the metal porous membrane in a direction from the second principal surface of the metal porous membrane toward the first principal surface.

Abstract: A filter device through which a fluid containing a target substance and a coarse substance larger than the target substance is passed to selectively collect the target substance from the fluid. The filter device includes a prefilter that removes the coarse substance and a collection filter that collects the target substance. The prefilter and the collection filter are arranged in series such that the fluid passes through the prefilter and then through the collection filter. The prefilter includes a cavity arrangement structure having a pair of opposing main surfaces and a plurality of cavities extending through both main surfaces.

Abstract: A filter device that includes: a film section having multiple through-holes and a frame section surrounding a periphery of the film section; and a holding unit in a round or angular tubular shape, the holding unit having a groove on an inner wall of the holding unit that is constructed to hold the frame section of the filter. a size of the groove in an extending direction of the holding unit is larger than a thickness of the filter. A diameter of a first inscribed circle which contacts a surface of a recessed portion of the groove is larger than a second diameter of an inscribed circle which contacts an outer periphery of the filter.

Abstract: A filter that includes a filter base portion having a first main surface and a second main surface opposite to the first main surface, the filter base portion defining multiple first through-holes and one or multiple second through-holes penetrating between the first main surface and the second main surface, the one or multiple second through-holes being larger in size than the multiple first through-holes. The filter base portion having a first region on a center side of a filter, a second region on an outer periphery side of the filter relative to the first region, and a third region between the second region and an outer periphery of the filter. The one or multiple second through-holes are in the second region, and a ratio of an opening area of the one or multiple second through-holes is less than a ratio of an opening area of the multiple first through-holes.
