  • Patent number: 10369745
    Abstract: The present invention relates to a membrane and a method for manufacturing a membrane for filtering a fluid, said membrane comprising: a substrate having a three-dimensional structure and consisting of an one-piece ceramic porous body; and at least one separating filtering layer having a porosity that is lower than that of the substrate, in which the three-dimensional structure of the substrate is produced by forming elemental layers that are stacked and connected in series with one another, by repeating steps: a) depositing a continuous bed of powder at least partially consisting of a powder intended for forming the ceramic porous body; b) locally consolidating, part of the deposited material such as to create the elemental layer, and simultaneously linking the elemental layer thus formed with the preceding layer such as to gradually grow the desired three-dimensional shape.

  • Patent number: 9731229
    Abstract: A filtering element for the filtration of a fluid medium comprises a rigid porous support of cylindrical shape having a longitudinal central axis (A) and a plurality of channels for the circulation of the fluid medium to be filtered and collection of filtrate on the periphery of the support. The channels are arranged in the support parallel to its central axis central (A) and define at least three filtering zones which are distributed concentrically and separated from each other by a continuous porous zone. The mean thickness of the porous zone (Z1) closest to the central axis (A) is smaller than the mean thickness of the porous zone (Zn-1) the closest to the periphery of the support (1) and, in the direction moving away from the central axis (A) of the support towards its periphery, the mean thickness of a porous zone is either identical to the next or smaller.

  • Patent number: 9522351
    Abstract: A filtration element for filtering a fluid medium comprising a rigid porous support of cylindrical shape having a longitudinal central axis (A) and comprising a plurality of channels for the circulation of the fluid medium to be filtered with a view to recovering a filtrate at the periphery of the support. The channels are parallel to a central axis of the support.
