    Patent number: 10814282
    Abstract: A filter element for a filter apparatus includes at least one filter member and a frame member arranged to support the at least one filter member in such a manner that an internal cavity is formed. The filter member includes a permeable membrane layer which has a first filter surface for receiving a pressure and directed towards an internal cavity arranged in-side the filter element, and a second filter surface for receiving solid particles filtered from a feed. The filter member forms a capillary filter.

  • CERAMIC FILTER ELEMENT AND METHOD FOR MANUFACTURING A CERAMIC FILTER ELEMENT
    Publication number: 20140346104
    Abstract: The invention relates to a ceramic filter element (22) for removal of liquid from solids containing material in a capillary suction dryer. The filter element comprises a ceramic substrate covered by a sintered ceramic microporous layer (31). The sintered microporous membrane layer is provided with coarse solid particles (71) of a particle size larger than a pore size of the membrane material layer (31) so as to form a textured surface (50) which prevents a filter cake from sliding off the surface of the filter element prior to the intended cake discharge.
