The present invention relates to a membrane module support frame for membrane bio-reactor (MBR), and more particularly, to allow the membrane module to be firmly fixed while being easily disposed at a constant interval on the membrane module support frame. The present invention relates to a membrane module support frame for improving durability of a membrane module by preventing side effects such as from occurring.

A membrane is a phase that can separate only a specific component from a gas, liquid, solid, or mixture thereof. A membrane separation is a separation in which a mixture of molecules is separated using a physicochemical property of the membrane. Way.

Membranes in the field of water treatment are classified into porous membranes, microporous membranes, and homogeneous membranes according to their structure, and are classified into microfiltration membranes, ultrafiltration membranes, reverse osmosis membranes, gas separation membranes, permeation evaporation membranes, and the like according to their use. In general, the membrane is difficult to be used alone, and the membrane is used so that the membrane can be used in a separation process, and the facility in which the membrane is inserted and configured is called a module. Depending on the type of membrane, flat modules, tubular modules, hollow fiber membrane modules, etc. are commercially used, and two types of hollow fiber membrane modules are pressurized and suction type (immersion type), and tubular membranes are used as pressurized. The pressurized type of hollow fiber membrane and tubular membrane has to maintain a certain linear velocity in the membrane in order to reduce the contamination of the membrane, which causes a lot of power costs. The suction type of the hollow fiber membrane reduces the contamination by colliding air bubbles on the surface of the membrane in water, and sometimes the membrane is entangled with fibrous contaminants to damage the membrane itself. The membrane type refers to a membrane formed on a plane or a sheet, and contaminants do not adhere well, and contaminants are easily removed, and there is little concern that the membrane may be damaged during operation compared to the hollow fiber membrane. However, unlike hollow fiber membranes, there is also a disadvantage that the membrane cannot be cleaned by backwashing.

Membrane modules are selected for conditions such as membrane filling rate, acceptable raw water solute concentration, physical cleaning resistance, and removal efficiency. Membrane module life and throughput are also greatly influenced by the structure and strength of the membrane itself and the design and structure of the membrane module.

1 shows a conventional water treatment membrane module 1. The membrane module 1 is composed of a membrane assembly 2 and the frame (3). The discharge port 4 is generally provided on the upper side of the frame 3. The membrane module 1 for water treatment of this structure is installed in an aeration tank in which contaminated water is accommodated. A discharge port 4 provided above the frame 3 of the membrane module 1 is connected to a discharge pump (not shown). When the discharge pump mentioned in the previous sentence is operated, solids of a predetermined size or more, such as sludge contained in the brine, are not introduced into the membrane assembly 2 by the differential pressure, and only a liquid having a predetermined size or less is supplied to the membrane assembly. It flows into the inside of (2). The liquid introduced into the membrane assembly 2 is discharged upward through the discharge port 4 provided above the frame 3 of the membrane module 1 to treat contaminated water.

The separation membrane module 1 for water treatment is installed in the aeration tank while being supported by the separation membrane module support frame 5 as shown in FIG. 2. In this case, as shown in FIG. 2, a plurality of space keeping members 6 are fixedly arranged at regular intervals on the main body 7 of the support frame 5. These spacing members 6 allow each membrane module 1 for water treatment to be arranged at regular intervals. When the membrane module 1 is installed in the membrane module support frame 5, the interval between the membrane modules 1 should be kept constant so that the upward water flow is kept constant so that the water treatment can be performed smoothly.

The space keeping member 6 is generally provided in the membrane module support frame 5 by attaching it to the main body 7 of the membrane module support frame 5 during manufacture of the membrane module support frame 5.

As shown in FIG. 3, the membrane module 1 is mounted between the gap holding member 6 and the gap holding member 6, and the gap between the gap holding members 6 is easily mounted by the membrane module 1. It is kept slightly wider than the thickness of the membrane module (1). The free space formed between the angular holding member 6 and the membrane module 1 prevents the membrane modules 1 from being maintained at regular intervals and causes problems such as the membrane module 1 shaking and bending due to aeration at the bottom. Let's go.

The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to ensure that the membrane module is firmly fixed while being easily arranged at a constant interval to the membrane module support frame, swinging, bending of the membrane module It is to provide a membrane module support frame to improve the durability of the membrane module by preventing side effects such as to occur.

In order to achieve the above object, the present invention

In the present invention, the connecting bolt 11 is fixed by the nut 12 on the main body side of the support frame (5).

As mentioned above, the membrane module support frame according to the present invention is to be securely fixed while being easily disposed at a predetermined interval to the membrane module support frame to prevent side effects such as fluctuation, bending, etc. of the membrane module. This improves the durability of the membrane module.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

4 is a view showing that the membrane module 1 is installed in the membrane module support frame 5 according to a preferred embodiment of the present invention (as seen from above), and FIG. 5 shows a preferred embodiment of the present invention. Accordingly, the membrane module 1 is shown in a perspective view of the membrane module support frame 5 is installed. The membrane module support frame 5 according to the present invention accommodates one or more membrane modules 1 for water treatment and is installed in the aeration tank together with the membrane module 1 for water treatment.

4 and 5 together, the membrane module support frame 5 according to a preferred embodiment of the present invention is one or more interval maintaining member 6 for maintaining each of the membrane modules (1) for water treatment at a predetermined interval Include).
