ABSTRACT:
An improved tubular membrane filtration module including an outer cylinder and a plurality of water permeable non-woven fabric pipes formed on the inside thereof, the non-woven fabric pipes being inserted into the outer cylinder in a closely bundled state, the spaces between the fabric pipes and the outer cylinder at each end thereof being filled with hardened synthetic resin to fix and seal the assembly. The ends of the non-woven fabric pipes are coated with a resin such that the inside coating of resin at the end of the fabric pipes is less than that on the inside thereof.
