A wedge-shaped jig (6) is inserted into a gap between a first substrate (21) and a second substrate (22) at a corner (221) of the second substrate (22) and separation of the attached first substrate (21) and second substrate (22) starts to proceed; then, a second suction pad (53) of a second suction portion (51), which is the closest to the corner (221), moves upward. Then, first suction pads (43) of first suction portions (41a), (41b), and (41c) sequentially move upward such that one side of the second substrate (22) separates from the stacked body. Although the second substrate (22) warps as the separation of the second substrate (22) proceeds, each of the plurality of first suction pads (43) elastically deforms. Therefore, the first suction pads (43) can be prevented from being detached from the second substrate (22), and the substrate (22) can be securely separated from the stacked body.

A biological method of water disposal that avoids disadvantages caused by an increase of the number of membrane filter units attributed to an increase of the volume of sludge disposed of, maintaining a given rate of sludge disposed of. Four or more membrane filter units (5) are immersed and laid at given intervals in series in aeration tank (4). The amount of suctioned filtrate water of each membrane filter unit (5) and / or the amount of air emitted toward each membrane filter unit (5) is sequentially increased from the raw water inflow side to the sludge discharge side. Accordingly, in response to the amount of solid matter adhering to the membrane surface of membrane filter units (5) on the sludge recovery side, the solid matter can be unfailingly detached from the membrane surface. Simultaneously, the sludge concentration at edge portions of the recovery side exhibiting the highest sludge concentration would be increased, thereby facilitating the discarding operation of recovered sludge and further realizing reduction of drying energy at discarding. Moreover, the discharge of filtrate water can be efficiently carried out.
