摘要

The filter medium (2) for solid-free extraction of process water (5) from digester outputs (1) that are emerged through biological dismantling of renewable raw materials and biogenic raw materials, comprises a structure that is formed from coarse materials contained in the digester outputs. The coarse material has dimension of greater than 1 and has an elongated and/or fibrous form/structure. The structure is fabric structure or braid structure. The structure exists from the fine materials of the digester outputs. An independent claim is included for a method for solid-free extraction of process water from digester outputs.
