[0002] Ultrafiltration membrane is an artificial permeable membrane used in the ultrafiltration process. It is generally made of polymer materials such as cellulose acetate, cellulose acetate ester, polyethylene, polysulfone and polyamide. It is generally pre-made into various types of membrane components such as tubular, plate, roll, capillary, etc., and then multiple components are assembled together for use to increase the filtration area.

[0003] When installing and replacing the ultrafiltration membrane assembly, you need to first remove the end plates at both ends of the membrane shell. There are 3 positioning bolts on the end plates. When disassembling, first unscrew the 3 positioning bolts and remove the retaining ring; then screw the 3 positioning bolts into the positioning holes, use a crowbar to pry the positioning bolts and remove the end plates. Because the positioning bolts are small in diameter and long in length, the removal process takes a lot of time, which seriously restricts the progress of installation and replacement and makes it difficult to remove the end plates.
