The Flocculation of Pulp Fibres

This paper reviews current knowledge of pulp flocculation over the entire range of consistency found in pulping and papermaking, from dilute suspensions of fibres in water to dry fibres suspended in air. Some of the key factors that govern flocculation in low consistency aqueous suspensions are shown to apply with changing emphasis over the entire consistency range. Several recent findings from our laboratory that fill gaps in current knowledge are also reported.
