Abstract
The present invention relates to a porous monolithic support (1) for filtration membranes containing channels (2, 3, 4), the internal surface of which supports the membranes (14, 15, 16), characterized in that the said support contains at least two channels, all of said channels having: (a) substantially similar sections, (b) interchannel partitions (5, 6, 7) and partitions with the outside of the support (8, 9, 10) of substantially constant thickness and (c) a partition with the outside of the support of substantially the same surface area. Application to the tangential filtration of viscous fluids and/or of fluids containing solid materials.

Porous monolithic support for filtration membranes containing channels, the internal surface of which supports the membranes, wherein said support has a central axis of symmetry and contains at least two channels identically arranged within said support all of said channels having:
- (a) substantially similar sections, and
- (b) interchannel partitions and partitions with the outside of the support of substantially constant thickness.
