What is coagulation and flocculation?
Coagulation is the destabilization of colloidal particles brought about by the addition of a chemical reagent called as coagulant. Flocculation is the agglomeration of destabilized particles into microfloc and after into bulky floccules which can be settled called floc.
What is the meaning of flocculation?
Flocculation, in the field of chemistry, is a process by which colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent.
What are flocculants and coagulants?
Flocculation and Coagulation in water treatment are used to remove suspended solids through a process that destabilizes the suspended particles in water solutions. The difference between the two is coagulation is the coming together, or clumping of particles, and flocculation is the settling of coagulated particles.
What is coagulation of water?
Coagulation is the chemical water treatment process used to remove solids from water, by manipulating electrostatic charges of particles suspended in water. This process introduces small, highly charged molecules into water to destabilize the charges on particles, colloids, or oily materials in suspension.
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 is mean by coagulants?
noun. a substance that aids or produces coagulation.
What is flocculation with example?
Flocculation is the collection of cells into aggregates by the addition of multivalent cations, metal salts or polymers (for example, polyaluminum chloride).
What is a coagulant definition?
noun. a substance that aids or produces coagulation. Word Frequency.
What is a flocculant used for?
Flocculants. Flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering.
What are coagulants examples?
Examples of primary coagulants are metallic salts, such as aluminum sulfate (referred to as alum), ferric sulfate, and ferric chloride. Cationic polymers may also be used as primary coagulants.
What is an example of coagulation?
Examples of Coagulation
Milk proteins coagulate to thicken the mixture that forms yogurt. Blood platelets coagulate blood to seal a wound. Pectin gels (coagulates) a jam. Gravy coagulates as it cools.
What is the process of coagulation?
coagulation, in physiology, the process by which a blood clot is formed. The formation of a clot is often referred to as secondary hemostasis, because it forms the second stage in the process of arresting the loss of blood from a ruptured vessel.
What is an example of flocculation?

What is flocculation in water treatment?
Flocculation is a water treatment process where solids form larger clusters, or flocs, to be removed from water. This process can happen spontaneously, or with the help of chemical agents. It is a common method of stormwater treatment, wastewater treatment, and in the purification of drinking water.
What causes coagulation?
Blood vessels shrink so that less blood will leak out. Tiny cells in the blood called platelets stick together around the wound to patch the leak. Blood proteins and platelets come together and form what is known as a fibrin clot. The clot acts like a mesh to stop the bleeding.
What is coagulation give two examples?
What are the 4 steps of coagulation?
1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.

What are the 3 stages of water treatment?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.
What is the principle of coagulation?
At a glance
| Working Principle | Suspended particles are destabilised by addition of a clarifying agent leading to the neutralisation of their charges. Particles thus agglomerate (flocs formation) and are able to decant. |
|---|---|
| Main strength | Removes solids and improves filtration |
| Main weakness | Continuous input of chemicals required |
Is blood a coagulation?
Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
