• at least one perforated and structured filter plate (2), and
• an interior space (13) defined within the filter sector (1), wherein
• the filter plate (2) is configured to be suctioned via the interior space (13) of the filter sector (1) for separating liquid from a suspension, and
• the filter plate (2) comprises at least one arch structure (3) with a polygonal base (4), the polygonal base (4) of the arch structure (3) being a hexagon.

• a rotating hollow shaft (12) having a circumference;
• and
• at least one filter disc (11), comprising:
• at least one perforated and structured filter plate (2), and
• an interior space (13) defined within the filter sector (1), wherein
• the filter plate (2) is configured to be suctioned via the interior space (13) of the filter sector (1) for separating liquid from a suspension, and
• the filter plate (2) comprises at least one arch structure (3) with a polygonal base (4), the polygonal base (4) of the arch structure (3) being a hexagon comprises several filter sectors (1) according to any one of claims 1 to 13, wherein
• the filter sectors (1) are fastened to the circumference of the hollow shaft (12), and
