What is an example of flocculation?
Flocculants gather the destabilized particles together and cause them to agglomerate and drop out of solution. Examples of ChemTreat flocculants include low-, medium-, and high-molecular weight polymers.Flocculants gather the destabilized particles together and cause them to agglomerate and drop out of solution.

What you mean by flocs?
Floc is a small, loosely aggregated mass of flocculent material suspended in or precipitated from a liquid. It consists of finely divided suspended particles in a larger, usually gelatinous particle, the result of physical attraction or adhesion to a coagulant compound.24 Nov 2016
What is flocculation in water treatment?
What is flocculation? Flocculation is the separation of a solution, commonly the removal of sediment from a fluid. The term is derived from floc, which means flakes of material; and when a solution has been flocculated, the sediment has formed into larger aggregated flakes, making them easier to see and remove.
How is flocculation used in everyday life?
Flocculation: Particles that aggregate by the use of polymers that binds them together. They are typically used for treatment of wastewater containing colloids (suspended particles) and metal ions. But the phenomena are also well-known from everyday life especially coagulation. A good example is sour milk.9 Oct 2015
Where is flocculation used?
Flocculation leading to sedimentation is both used in the purification of drinking water, as well as for sewage, storm water, and industrial wastewater treatment. This is why flocculants are largely known for being water treatment plant chemicals.
What can be used as a flocculant?
– Moringa oleifera seeds (Horseradish Tree)
– Strychnos potatorum seeds (Nirmali nut tree)
– Guar gum.
– Alginates (brown seaweed extracts)
What is flocculation simple?
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.
What is the difference between settling and flocculation?
Surface chemistry In colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float to the top of the liquid (creaming), settle to the bottom of the liquid (sedimentation), or be readily filtered from the liquid.
What is coagulant and flocculant?
Coagulation and flocculation are two separate processes, used in succession, to overcome the forces stabilising the suspended particles. While coagulation neutralises the charges on the particles, flocculation enables them to bind together, making them bigger, so that they can be more easily separated from the liquid.
What is meant by flocculation?
Flocculation is a process by which a chemical coagulant added to the water acts to facilitate bonding between particles, creating larger aggregates which are easier to separate.
What is chemical coagulation and flocculation?
Chemical coagulation and flocculation in wastewater treatment involves the addition of chemicals to alter the physical state of dissolved and suspended solids and facilitate their removal by sedimentation.
What is flocculation example?
Flocculation is the collection of cells into aggregates by the addition of multivalent cations, metal salts or polymers (for example, polyaluminum chloride).
What chemicals are used in coagulation and flocculation?
The iron coagulants include ferric sulfate, ferrous sulfate, ferric chloride and ferric chloride sulfate. Other chemicals used as coagulants include hydrated lime and magnesium carbonate.
