Abstract (en)

[origin: WO2012022528A2] The method serves to filter suspensions (S1, S2), in particular cellulose fibres in aqueous suspensions. Here, at least two different suspensions (S1, S2) are filtered in a filter device, in particular a disc filter, with the result that filtrates (F1, F2) are formed as through-feed and thick stock is formed as residue. The method is preferably regulated by virtue of the fact that both the vacuums for filtrate extraction and the rotational speed of the hollow shaft (3) are incorporated into the regulating concept.
