4320-004 ROGERS, BERESKIN /A PARR C A N A D A Title: TUBULAR MEMBRANE MODULE Inventors: Robert William Langerak Paul B. Koehler Fernando A. Tonelli Radu Apostolache A tubular membrane module for use in ultrafiltration or microfiltration has a bundle of membrane tubes that extend between inlet and return headers. The inlet header is fixed to one end of a tubular housing having a permeate outlet while the return header is free to float longitudinally of the housing to accomodate dimensional changes in the tubes with respect to the housing. The tubes are sealed at their ends in sockets in respective potting collars but are mechanically secured and sealed to the headers. The sockets are undercut to protect the membranes from stripping due to fluid shear.
