Abstract

To provide a cleaner pulp and to obtain a higher chemical recovery during washing of chemically cooked and optionally defibrated cellulose pulp, the partially washed pulp is subjected to a mild mechanical treatment e.g. in a device (10) adapted for high-consistency treatment and provided with screwsrotating relative to each other, said treatment taking place between at least one pair of conventional washing stages (4,14).
