Abstract

The invention relates to a hollow fiber ultra-filtration membrane assembly having an improved central conduit structure which comprises a pressure-bearing shell. An end cover is arranged on two ends of the pressure-bearing shell. A hollow conduit is axially arranged on the center of the pressure-bearing shell, an ultra-filtration membrane is arranged between the hollow conduit and the inner wall of the pressure-bearing shell while two ends of the ultra-filtration membrane are provided with sealants, and a long hole is arranged on the central conduct. The invention has the advantages that the water outflow speed is increased so the membrane assembly can be easily washed.

Description
