A device which is suitable for treating a fluid comprises an elongated foil formed of a plurality of foil layers arranged in zigzag fashion, wherein a first foil layer is connected to a second foil layer at a first end. The second foil layer is connected to a third foil layer at a second end remote from the first end. Spacers are arranged between said foil layers. The spacer comprises a mesh-like layer, through which fluid can flow in the plane of the mesh-like layer as well as transversely to the plane of the mesh-like layer.
