Abstract

PURPOSE:To eliminate the difference of a separation result between sections by making the pressure between the front and back surfaces of the separation membrane of each section constant, by providing a membrane water transmitting amount regulation valve to the membrane transmitted liquid outlet of each section of a plate and frame type membrane separation apparatus. CONSTITUTION:In a plate and frame type membrane separation module wherein a plurality of divided sections S-1-S-4 are arranged in series, membrane water transmitting amount regulation valves (a)-(d) are arranged to the membrane transmitted liquid outlets of the sections S1-S4. A liquid A to be treated is supplied by a pump to be passed through said sections in order from the section S-4 while the membrane transmitted liquid B flows to the support of each membrane to be taken out from piping through each of flowmeters 1-4 at every section. At this time, the membrane transmitting flow speed from each section is set to an optimum condition by operating each of the valves (a)-(d) to make the composition from each section constant and the transmitted liquids from the sections S1-S4 are gathered to one piping to be taken out through a flowmeter 5.

[Detailed Description of the Invention] [Industrial Field of Application] The present invention can be roughly divided into four types: a plate-and-frame type equipped with an ultrafiltration membrane or a microfiltration membrane. Typical forms of membrane separation devices are described, for example, in Japanese Patent Publication No. 55-35553 or Japanese Patent Publication No. 55-17608. The main feature of this device is that it is equipped with a large number of sheet-like separation membranes to ensure the necessary membrane area. Normally, a plate-and-frame membrane separator has a structure in which the inside of the membrane separator is divided into multiple sections, each section is substantially arranged in series, and each section has multiple membranes arranged in parallel. has been done. The reason for dividing the inside of the device into a plurality of sections is to reduce the amount of liquid fed into the separation device. Traditional plate-and-frame membrane separation systems use a feed tank.

It consists of a feed liquid pressure pump, a membrane separation device (sometimes called a module), a pressure gauge, a flow meter, and piping. Then, the feed liquid to be separated is pumped from the tank into the membrane separator, passes through each section of the membrane separator, and most of the membrane content is circulated within the system. . On the other hand, when the feed liquid passes through the membrane separation device, a portion of the feed liquid passes through the membrane and moves to the porous support plate that supports the membrane. This is the membrane permeate.

The membrane permeate liquid is led out from the support plate through the tube, and the membrane permeate liquid led out from all the support plates is collected into one water collecting pipe.

In such a membrane separation device, pressure loss is large because multiple sections are connected in series inside the device.
There tends to be a difference between the amount of water permeable from the inlet section of the device and the amount of water permeable from the outlet side.

We also found that the difference in membrane permeation flow rate has a large effect on the membrane separation results. Therefore, in conventionally used devices, there are differences in the composition of the membrane permeate between the sections partitioned within the device, making it difficult to obtain a membrane permeate having a constant composition.

In the present invention, the membrane-permeated liquid is collected in one place for each section, each section is connected to one pipe, and each pipe is provided with a flow rate regulating valve. It is desirable that the piping from each section to the membrane water permeation control valve be pressure resistant. Preferred examples of such long tubes include tetrafluoroethylene tubes, wired polyethylene tubes, and stainless steel tubes. Also,
The most desirable membrane water permeation rate adjustment valve is a needle valve that allows for minute adjustments, but other methods include ball valves and diamonds. It is desirable to pass through a dedicated flow meter, the reading of which simplifies flow adjustment.

Bovine serum r-globulin 509 was dissolved in 5 t of physiological saline and used as a sample solution. The sample solution was placed in a tank and was pumped into the module at a flow rate of 10 t/min using a rotary pump. At this time, the module inlet pressure is 1.2 kg/7
.. The outlet pressure was 0.2 to 9/ad. In the above operation, the membrane permeate composition and membrane permeation flow rate when the permeate adjustment pulp of each section was fully opened are shown in Table 1 as a comparative example. In the table, the section number is 1 for the highest pressure section. It can be seen that the membrane permeate composition differs in each section, and that only a few sections are effectively utilized.

Although each section is provided with a permeate adjustment valve, this operation is substantially the same as the conventional membrane separation method, with all the valves being fully open.

Next, in the comparative example, it was Section 5 (lowest pressure section) that gave the best separation results. Therefore, by operating the permeate adjustment pulp of each section, the water permeation amount of all sections was adjusted with the needle valve, which is the withdrawal water distribution control valve, when the water permeation rate of section 5 in the comparative example was 9.5L/ff1''. The results are shown in Table 1 as an example.It can be seen that by adjusting the rate of desorbed water in this operation, a highly concentrated membrane permeate liquid was obtained, and all the membranes effectively exhibited their separation performance.
