PURPOSE: A separating membrane unit for a sedimentation type membrane separating apparatus is provided to firmly fasten a pressurizing bolt which pushes the headers of hollow fiber membrane modules by fastening a fastening part at the end part of the pressurizing bolt. CONSTITUTION: A separating membrane unit for a sedimentation type membrane separating apparatus includes a separating membrane frame, blocking plates, a plurality of hollow fiber membrane modules, a module support(140), a bolt hole(160), a pressurizing bolt(170), and a fastening part(176). The blocking plates block the lateral side of the separating membrane frame. The hollow fiber membrane modules are installed in a space between the blocking plates. The module support supports the headers of the hollow fiber membrane modules. The bolt hole is formed at a blocking plate. The head part of the pressurizing bolt is positioned at the blocking part, and the shank part of the pressurizing bolt is fastened with the bolt hole. The fastening part is formed at the end part of the shank part of the pressurizing bolt. |
