Abrasion-proof filtration membrane and method of producing said membrane
A filtration membrane (1) is provided that includes a porous support (4) and a membrane layer having a first and a second zone (2, 3). The first zone (2) has a thickness of 5 to 15 μm and an average pore opening size of smaller/equal 0.4 and the second zone (3) has a thickness of 5 to 40 μm and an a...

| Zusammenfassung: | A filtration membrane (1) is provided that includes a porous support (4) and a membrane layer having a first and a second zone (2, 3). The first zone (2) has a thickness of 5 to 15 μm and an average pore opening size of smaller/equal 0.4 and the second zone (3) has a thickness of 5 to 40 μm and an average pore opening size of 0.5 to 5.0 μm. The filtration membrane (1) is produced by forming a single- or -double-layer coating on the porous support (4). |
