Abstract

A method of assembling a rigid element in a module, the rigid element having a membrane for separation, filtration, or catalytic transformation purposes. The outside shape of the element is substantially cylindrical or prismatic. The element is made from a support of sintered substance, the ends thereof are sealed, and an active layer is deposited thereon. The module is intended to contain at least one rigid element within a shell which is substantially cylindrical about an axis parallel to said rigid element and closed by two end plates having openings to which the ends of the elements are fixed, together with intervening seals. Each of the ends is provided with an extra thickness which is bonded to the support. The extra thickness mass is machined in such a manner as to obtain a shoulder whose outside surface has a predetermined circularly-symmetrical shape about an axis close to that of the element.
