Flocculation, in physical chemistry, separation of solid particles from a liquid to form loose aggregations or soft flakes. These flocculates are easily disrupted, being held together only by a force analogous to the surface tension of a liquid. In industrial processes, flocculation may be a
Clarifying agentOverviewProcessAgentsSee also
Particles finer than 0.1 µm (10 m) in water remain continuously in motion due to electrostatic charge (often negative) which causes them to repel each other. Once their electrostatic charge is neutralized by the use of a coagulant chemical, the finer particles start to collide and agglomerate (collect together) under the influence of Van der Waals forces. These larger and heavier particles are called flocs. Flocculants, or flocculating agents (also known as flocking agents), are chemicals that promote floccula

2018-04-03· Flocculants come in various charges, charge densities, molecular weights and forms, and they have also been around for centuries. Natural polymers, such as crushed nuts, have been used as flocculants since prehistoric times by some central African tribes. Coagulation, flocculation
Flocculation Theory and Background
Flocculant A shows a weak flocculation performance and is hardly able to reduce the amount of small particles in the system. Flocculant B captures a considerable quantity of small particles. However, flocculation kinetics are slow and the floc breakage rate is higher than the point of optimal flocculation.
