Aggregation of colloidal material in recycling process water
Source abstract
Abstract
The aggregation of microstickies and pitch in white water into larger particles and deposits was studied with particle size measurements. Microstickies can cycle in process water if their concentration is high enough. The particle size of the stable colloidal material is a balance between the attractive forces among micro-stickies and the disruption caused by shear. The effective measurement of micro-organic accumulation (EMMA) potential (a measure of size-fractionated colloidal material) can track the particles in the size range that leads to dep-osition. Pitch and microstickies destabilize each other, which explains why mixing mechanical and recycle pulps can cause unusually high deposit problems.
