Clamp type RO membrane shell

Clamp-type membrane housings are key components used in water treatment equipment to house reverse osmosis membranes and other filtration membrane elements. They are widely used in the water treatment field due to their unique connection methods and performance characteristics. The following is a detailed introduction:

Structural Composition

 The membrane housing is typically a hollow cylindrical structure, made of fiberglass or stainless steel. Fiberglass membrane housings offer advantages such as light weight, high strength, and excellent corrosion resistance; stainless steel membrane housings offer high pressure resistance and excellent hygiene.

End caps: Located at each end of the membrane housing, they are generally made of plastic or ABS. They feature side and center holes for the intake of raw water and the discharge of filtered water. Positioning posts are also located inside the end caps, which mate with positioning holes at the front and rear ends of the filter membrane to position and limit the membrane.

The clamp is a key connecting component of the clamp-type membrane housing, generally consisting of two connectors and a screw. The connector is mirror-symmetrical, consisting of a central arc edge and a straight plate. The inner side of the central arc edge has a slot for inserting into the steps of the membrane housing body and end caps. The straight plate has a through hole for the screw to pass through. By rotating the nut, the two connectors are tightened, thereby tightening the membrane housing body and end caps, achieving a sealed connection.

Features

Easy Installation: The clamp-locking mechanism eliminates the need for individually tightening bolts like with flanged membrane housings, making assembly and disassembly faster and significantly improving installation and maintenance efficiency.

Good Sealing: Sealing rings, such as silicone O-rings, are typically installed between the clamp and the membrane housing and end caps to effectively prevent water leakage and ensure the sealing performance of the membrane housing. Designs such as flow equalizers on the end caps also help improve sealing and water flow uniformity.

Strong Pressure Resistance: The pressure resistance of clamp-type membrane housings varies depending on the material and manufacturing process, but they can generally withstand pressures of 2.0-2.5 MPa. Membrane housings made from seamless stainless steel tubing offer even higher pressure resistance, meeting the pressure requirements of most reverse osmosis water treatment systems.

Easy Maintenance: Easy assembly and disassembly simplifies membrane element replacement, cleaning, and maintenance, reducing maintenance time and costs.
