ABSTRACT:
A tubular membrane module for example for use in ultrafiltration has a tubular shell made of standard PVC pipe and moulded PVC end fittings. A series of membrane tubes within the shell extend between coupling members at both ends. The coupling members fit closely inside the shell and end fittings and are secured in place using epoxy adhesive. A transverse wall in each coupling member is provided with sockets which receive the ends of the tubes and in which the tubes are secured by a similar adhesive. Each socket has a blind end that receives the end portion of the tube so that the tube is protected from shear effects due to fluid entering the tube under pressure in use.
