Abstract

The present invention relates to a process for removal of solid non fibrous material from an aqueous pulp suspension comprising providing an aqueous pulp suspension comprising solid non fibrous material removing at least part of the solid non fibrous material from the aqueous pulp suspension thereby forming an aqueous pulp suspension depleted in solid non fibrous material dewatering the aqueous pulp suspension depleted in solid non fibrous material thereby forming a web comprising cellulose containing fibres and a filtrate comprising residual solid non fibrous material removing at least part of the residual solid non fibrous material from the filtrate thereby forming a filtrate depleted in residual solid non fibrous material and an aqueous stream comprising at least part of the removed residual solid non fibrous material and diluting the aqueous pulp suspension and/or the aqueous pulp suspension depleted in solid non fibrous material with at least part of the filtrate depleted in residual solid non fibrous material whereby the aqueous stream comprising at least part of the removed residual solid non fibrous material is purged from the system.
