摘要：
The process for cleaning fibrous suspension in a multi-stage cleaner plant, in which one part is led off from the first stage as accept and the remaining part of the first stage is further prepared in subsequent stages. The cleaners (1) of the first stage (S1) serve to prepare three fractions including the accept fraction, and an accept content of at most between 35% and 45% is removed from these cleaners. In this way, the number of cleaners. In this way, the number of cleaners in the process can be reduced.
