Abstract
An arrangement is disclosed for the diffusion of substances between two fluids via semipermeable membranes. The membranes are arranged in a stack of at least two pairs of such membranes, a first fluid being conducted between the membranes in these pairs, while another fluid is conducted outside the same membranes, the membranes in the pairs being interconnected so that they form a grating of channels between themselves for the first fluid by being joined to one another at a plurality of points.
