The layer arrangement includes a plurality of layer subsystems each consisting of a periodic sequence of at least one period of individual layers. The periods include two individual layers composed of different material for a high refractive index layer and a low refractive index layer and have within each subsystem a constant thickness that deviates from a period thickness of an adjacent layer subsystem. The subsystem most distant from the substrate has (i) a number of periods greater than the number of periods for the layer subsystem that is second most distant from the substrate and/or (ii) a thickness of the high refractive index layer that deviates by more than 0.1 nm from that of the high refractive index layer of the subsystem that is second most distant from the substrate.

Abstract: The invention concerns a membrane separator for separating out low-colloidal and low-molecular contaminants as well as polyvalent ions (heavy metals) from aqueous media by means of a wound membrane element in which a corrugated distance piece (spacer) is positioned between the layers of the membrane windings. In cross-section the spacer (20, 30) has U-shaped crests (21) and troughs (22) with the legs (26) of the U-forms approximately perpendicular to the membrane surfaces (28), or triangular crests (31) and triangular troughs (32). The spacer (50) can consist of a plastic foil having a corrugated structure on both sides offset by one half-corrugation with respect to each other and where the crests (54, 54′) on both sides make contact with the layers of the membrane windings (4, 6). To increase the turbulence in the flow, the crests (56, 72) can have turbulence elements (60, 76).
