Abstract: The present invention refers to a method for the separation of a liquid mixture comprising water and a hydrophobic liquid, especially for oil-water separation, comprising the step of contacting the liquid mixture comprising the hydrophobic liquid and water with a hydrophilically coated mesh allowing water to pass through the mesh while at least part of the hydrophobic liquid remains on the mesh, wherein the mesh is a weave with a geometric pore size of less than 100 μηη having warp threads, the warp threads having a diameter dw, and shute threads, the shute threads having a diameter ds, wherein ds and dw differ by at least a factor of 1.1 and wherein the surface of the mesh is at least partly covered by a hydrophilic coating, the hydrophilic coating having a contact angle for water of less than 10°. The invention further relates to the hydrophilically coated mesh and its use.
