Abstract

The invention relates to a method for treating the white water from the production of fibre sheets with a machine of the paper machine type, comprising at least one step of recovery of the solid material contained in said white water (E, Y) from said machine, characterised in that said at least one recovery step for the material in suspension is achieved by means of centrifugation of said white water by means of a compact device (14, 17) forming at least two fractions from said white water, a fraction (Z) of clarified water and a fraction (T) with concentrated material in suspension.
