Abstract

A membrane filter has a feed inlet, a concentrated liquid outlet and a permeate outlet. Pairs of membranes are mounted on each side of a permeable support. The edges of the membrane units are sealed and a least one opening in the unit, normal to its surface, connected to a permeate offtake tube. Several membrane units are mounted parallel to each other in a pressure vessel. A failure of a section of membrane can be remedied by replacing one unit instead of the whole filter element.
