Abstract
A coiled membrane filter cartridge includes a central pipe having at least one axial row of openings through which fluid may radially pass into or out of the pipe and two superposed membranes wound in a plurality of turns about the pipe to form a membrane coil having opposite axial ends. The membranes are radially spaced from one another for defining, between themselves, a spiral flow channel being sealed at the axial ends. A fluidtight partition extends between the membranes and is connected thereto. The partition divides longitudinally the spiral flow channel into axially adjoining partial channels.
