First, referring to the separation membrane 120, the separation membrane 120 has a through hole 121 formed at a central portion thereof, and the third stock solution moving part 122 and the fourth stock solution are spaces on which one side of the separation solution may move without being filtered. The circular filter membrane in which the moving part 123 is formed overlaps two sheets.

In addition, the two filtration membranes are joined to each other by the joint 124, which is the remaining circumference except for the circumference of the through-hole 121 so that an inner space may be formed between the overlapped filtration membranes.

Therefore, the stock solution is filtered into the inner space from the outside of the separation membrane 120, the filtered filtrate may be discharged to the outside through the through-hole 121 formed in the center.

Here, the through-hole 111 formed in the center serves as a passage through which the filtrate moved to the inside of the separation membrane 120 is filtered out.

In addition, the first undiluted liquid moving part 112 and the second undiluted liquid moving part 113 are formed side by side in a smooth S-shape in an outward direction from the center of the disk 110, and are opposite to each other. One side of the inner wall surface is preferably provided with a flow blocking portion (114, 115) protruding up and down to block the flow of the stock solution.

Accordingly, when a plurality of disks 110 are stacked in the same direction, and the stock solution is introduced into the first stock solution moving unit 112, the stock solution is introduced between the disks 110. The stock solution introduced between the disks 110 flows to the surface of the disk 110 in a clockwise direction when viewed from the top because the flow to the second stock solution moving unit 113 is blocked by the flow blocking sections 114 and 115.

The stock solution that has reached the flow blockers 114 and 115 again is discharged through the second stock solution mover 113 because the flow to the first stock solution mover 112 is blocked by the flow blockers 114 and 115. .
The flow of the stock solution is illustrated by an arrow in FIG. 3A to help understand the flow of the stock solution described above.

Therefore, when a plurality of disks are stacked, the stock solution can flow between each disk and flow out of the disk surface. In addition, when the undiluted solution is introduced into the second undiluted liquid moving unit, since the undiluted liquid flows through the surface of the disk counterclockwise, the rotation direction of the undiluted liquid can be freely changed.

To be fixed.

In addition, the flow blocking portions 114 and 115 are preferably serrated surfaces having a plurality of protrusions formed in the vertical direction. Therefore, it is possible to reduce the phenomenon in which the undiluted solution hits the flow blocking parts 114 and 115 in the left and right direction, and smoothly passes through the first undiluted liquid moving part 112 and the second undiluted liquid moving part 113 along the valley of the sawtooth. .

In addition, a plurality of vortex protrusions 116 may protrude radially from the center of the disk 110 to vortex the liquid on the surface of the disk 110. When the stock solution is vortexed, the concentration polarization of the stock solution is lowered.

In addition, the third undiluted liquid moving part 122 and the fourth undiluted liquid moving part 123 formed on the separation membrane 120 may be formed of the first undiluted liquid moving part 112 and the second undiluted liquid moving part 113 formed on the disk 110. It is preferable to have a shape such as).
