The flocculation of cellulose powders with polymer flocculants

Abstract

The flocculation of pure cellulose, of mercerized cellulose and of cellulose treated with dilute nitric acid has been studied. The adsorption of polymer flocculants on the cellulose is described and results interpreted. Acid pretreatment caused maximum adsorption and flocculation.

The sedimentation behaviour of concentrated cellulose suspensions has been investigated for the determination of the “nominal radius” of cellulose particles and of related parameters.
