Abstract
The invention relates to a method for forming a membrane holder for applying in a tube filter, by mutually connecting a number of cassettes of V-shaped cross-sectional form, wherein a plurality of cassettes are placed successively and connected to each other in longitudinal direction in a row. The V-shaped cross -section of each cassette can herein be defined by two walls and a bridge piece located therebetween, wherein each wall has a number of cut-away portions. The cassettes can be mutually connected such that a cut-away portion in a wall of the one cassette is bridged by a full wall part of the other cassette. The cassettes can be mutually connected close to the base of their V-shaped cross-section, for instance by being snapped together. The invention further relates to a membrane holder obtained by applying this method, to cassettes for use in the method and in the membrane holder, and to a tube filter in which such a membrane holder is applied.
