FILTER ELEMENT AND METHOD FOR THE MANUFACTURE

摘要

The invention relates to a filter element and its manufacture to be used in removal of liquid from solids containing material to be dried in a capillary suction dryer which filter element contains a ceramic microporous layer havi ng the pore size under 5 micrometer and supported by a ceramic internal layer having recess areas (2) for liquid flowing. The internal layer is made of at least one substrate (1) which continuously surrounds at least one recess are a and which ceramic internal layer is surrounded by at least one essentially continuous microporous surface layer(3).
