Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a tubular membrane circulation device for efficient oil and impurity removal. Background Technology

[0002] A tubular membrane is a membrane module with separation function. It is made by bonding a membrane with separation function to the outer wall of a porous round tube such as sintered polyethylene, or to the wall of the central hole of the round tube, to form an external pressure tubular element or an internal pressure tubular element. The tubular element is then installed into a pressure-resistant sleeve to form a tubular module. Based on the pressure required for the membrane separation process, pumps and other equipment are matched and finally assembled into a tubular membrane device.
