Abstract

A method for washing a fibre suspension with washing liquid, in which, in accordance with the invention, the fibre suspension is introduced into an annular treatment channel ( 24 ) that has an inlet end ( 72 ) and an outlet end ( 73 ) and is concentric with an axis of rotation ( 5 ) to form an inner annular layer ( 74 ), washing liquid simultaneously being introduced into the treatment channel form an outer layer ( 75 ), which surrounds the inner annular layer. The fibre suspension and washing liquid are caused to rotate in the treatment channel whilst moving from said inlet end to said outlet end, fibres in the fibre suspension being caused to move into the outer layer of washing liquid, under the influence of the centripetal force, so that an accept ( 29 ), the liquid phase of which completely or mostly consists of washing liquid, is discharged at the outlet end of the treatment channel.
