Description of the Related Art In order to determine an optimum separation membrane for a processing stock solution, it is necessary to actually process and evaluate the stock solution using a separation membrane. FIG. 4 is a schematic sectional view showing a specific example of such a conventional separation membrane evaluation apparatus. In such a conventional separation membrane evaluation apparatus, the upper cell 100 and the lower cell 101 are combined to form a breakdown voltage cell. The upper cell 100 includes a stock solution introduction channel 102 and a concentrated solution discharge channel 103, while the lower cell 101 includes a permeate solution discharge channel 104. In the center of the upper surface of the lower cell 100, a separation membrane 10
A mounting portion 106, which is a recess for mounting 5, is provided. The mounting portion 106 has a permeated liquid channel material 107 laid thereon and
5 is placed, and a seal ring 108 is provided above the separation membrane 105.
Is incorporated. A permeated liquid discharge passage 104 is provided below the mounting portion 106 of the lower cell 101. The upper cell 100 is formed such that its lower surface is fitted with the mounting portion 106 of the lower cell 101, and is fastened between the lower cell 101 and the lower cell 101 through the seal ring 108 using fastening means such as bolts and nuts. The separation membrane 105 to be maintained is kept liquid-tight. The undiluted solution is pressurized by a pump or the like, introduced into the undiluted solution introduction passage 102, and supplied to the space between the lower surface of the upper cell 100 and the separation membrane 105. Then
The undiluted solution on the separation membrane 105 is discharged and circulated from the concentrated liquid discharge channel 103, while the filtered permeate is taken out from the permeated liquid discharge channel 104 to the outside.

により評価結果の信頼性が乏しい。In order to select an optimum separation membrane for a stock solution to be treated, a large number of separation membranes must be examined. However, the above-described conventional separation membrane evaluation apparatus can evaluate only one separation membrane at a time, and it is necessary to repeatedly replace and evaluate one separation membrane at a time.
For this reason, it takes time and effort to replace the separation membrane, and the overall evaluation time becomes longer. Further, in the case of a stock solution whose properties change with time, even if different separation membranes are evaluated over time, the reliability of the evaluation result is poor due to deterioration of the stock solution.

However, in such a method, the connection pipe from the pump and the connection pipe between the separation membrane evaluation device become long,
In addition, it takes time to prepare for evaluation, such as complexity, and the flow path resistance increases, which makes it difficult to set operating conditions, which is not preferable. In addition, in the conventional separation membrane evaluation device, the undiluted solution spreads from the undiluted solution introduction path onto the separation membrane surface and then flows to the concentrated liquid discharge path. In some cases, the flow velocity decreases as the distance from the periphery of the separation membrane increases, and a stagnation portion may occur. When the flow velocity difference is large as described above, highly reliable data on the performance of the separation membrane cannot be obtained.
