  • n. The process by which small particles of fine soils and sediments aggregate into larger lumps.

from The Century Dictionary and Cyclopedia

  • n. The act or process of becoming floccular; specifically, in chem. and physics, the union of small particles into granular aggregates or compound particles of larger size, under the influence of a moderate agitation in water or other fluid.

  • First, in a process called "flocculation," they add a solution that clusters dirt particles together so they can be filtered out.


  • Instead of the clean-cut criterion, French cheese-makers wait for "flocculation" to occur - the point when the milk starts to separate into curds and whey.

  • Deposition can also be caused by particle precipitation and flocculation.

  • Keith warns, however, that the yeast found at the bottom of the bottle is often a second strain added at the conditioning phase—typically a lager strain, used to ensure maximum flocculation during conditioning, and not the ale strain used in primary fermentation, where the distinctive esters are produced.


  • Excess levels of free amino nitrogen adversely affect flocculation, thus producing cloudier beers.


  • However, the flocculation/sedimentation process is already an advanced treatment technique requiring qualified personnel and well-equipped facilities; both scarce in rural areas of developing countries.

    1. Historical development and experience with water treatment

  • The natural water treatment potential was adopted long before chemical water treatment methods, such as chlorination and flocculation, were discovered and applied.

    1. Historical development and experience with water treatment

  • Worldwide practical experience revealed that the slow sand filter design concept was often misunderstood, the use of pretreatment processes, such as plain sedimentation or flocculation and sedimentation, were either inefficient or unreliable as well as inappropriate, and that operation and maintenance deficiencies contributed to the poor performance of slow sand filters.
