Abstract
A membrane holder for hollow fibre membranes, in particular for applying in a tube filter, includes a central pipe having spaced apart bands of inlet openings formed along a circumference of the central pipe to flow liquid through the central pipe, holding elements arranged around the central pipe, which holding elements have radially extending wall parts distributed along the circumference of the central pipe, and closing parts extending between the free ends of the radially extending wall parts for confining a bundle of hollow fibre membranes between two adjacent radially extending wall parts and a closing part, and deflector plates concentrically arranged around and spaced apart from the central pipe and, when viewed in radial direction, covering the bands of inlet openings.
