Abstract: 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 ?m and an average pore opening size of smaller/equal 0.4 and the second zone (3) has a thickness of 5 to 40 ?m and an average pore opening size of 0.5 to 5.0 ?m. The filtration membrane (1) is produced by forming a single- or -double-layer coating on the porous support (4).

Abstract: The invention relates to a filtration system that includes one or more flat filter, capillary tube filter, or wound filter modules having a single or double permeate drain on the edge side and fluid couplings for connecting the filter modules to a fluid distributor or additional filter modules. The fluid couplings include at least one passage each for permeate fluid, raw fluid, and concentrate fluid.
Abstract: The invention relates to a filter module having one or more spirally wound flat filter elements comprising permeate outlet openings on one or two edges, a method for the production of the filter module, and a filtration system formed from one or more filter modules.
Abstract: A spacer for devices for gas separation, reverse osmosis, forward osmosis, dialysis, micro-, ultra, or nano-filtration formed from a planar material which has a plurality of convex support elements having a footprint of 0.03 to 600 mm2 on one or both surfaces. The support elements are arranged on the planar material in a periodic pattern having a unit cell containing 2 to 100000 support elements. The unit cell has a surface coverage of 0.1 to 20%.
