    Flocculation of colloids or of fiber slurries

    Flocculation occurs in shear flow due to the fact that wood fibers have a length-to-thickness ratio of about 50 to 100. The action of charge-neutralizing additives such as alum or polyamines tends to increase fiber flocculation by a modest amount.

    Colloid definition, a substance made up of a system of particles with linear dimensions in the range of about 10−7 to 5 × 10−5 cm dispersed in a continuous gaseous, liquid, or solid medium whose properties depend on the large specific surface area. The particles can be large molecules like proteins, or solid, liquid, or gaseous aggregates and they remain dispersed indefinitely.

    A Flocculating Agent is a chemical that is added to liquids so as to promote the microscopically dispersed insoluble particles, i.e., collides and other suspended particles in the liquids, to aggregate and form flocs. The agent helps in the removal of these suspended particles as they either settle down to the bottom or float on the surface of

Colloidal clay: A colloid consists of one substance (or mixture of substances) very finely dispersed in another substance (or a mixture of substances) without a new true solution forming. So a colloid is a mixture of a dispersed phase and a continuous phase (disperse or continuous medium) BUT the dispersed phase is NOT dissolved in the continuous phase.
