What is the meaning of flocculation?

Flocculation is a process in chemistry wherein colloids are extracted from suspensions which then take the form of flake or floc. Flocculation is used for water purification, and can even be used to extract certain corrosive elements from water. Flocculation is also known as coagulation and agglomeration.

What is a flocculant in water treatment?

Flocculants are substances that promote the agglomeration of fine particles present in a solution, creating a floc, which then floats to the surface (flotation) or settles to the bottom (sedimentation). This can then be more easily removed from the liquid.

What is flocculation in soil science?

Definition. Flocculation – process during which particles, for example, of a soil, dispersed in a solution contact and adhere each another, forming clusters, flocks, flakes, or clumps of a larger size. The term originates from the word “floc,” which is the flake of precipitate that comes out of solution.

What is another word for flocculation?

Flocculation synonyms In this page you can discover 8 synonyms, antonyms, idiomatic expressions, and related words for flocculation, like: gelation, recrystallisation, emulsification, crystallization, sorption, nitrification, solubilization and densification.

Can you swim with flocculant in the pool?

If you’ve added flocculant, swimming in the pool is not recommended because it reduces the flocculant’s effectiveness. You should only swim after the particles have sunk and been removed from your pool floor.

How does flocculation occur?

In dispersed clay slurries, flocculation occurs after mechanical agitation ceases and the dispersed clay platelets spontaneously form flocs because of attractions between negative face charges and positive edge charges.

What is meant by coagulation and flocculation?

Coagulation and flocculation are used to separate the suspended solids portion from the water. Suspended particles vary in source, charge, particle size, shape, and density. Coagulation and flocculation occurs in successive steps, allowing particle collision and growth of floc.

How do I get rid of flocculant in my pool?

Vacuum the particle clumps from the bottom of your pool.

1. The movement of the vacuum may stir the particles up, clouding your pool again. If this happens, take a break, allow the particles to settle, then begin vacuuming again, and try to move slowly.
2. You may need to vacuum two or three times to remove all the clumps.

When should I use flocculant in pool?

Flocculants are a great way to clear up your pool fast, but you should only use the chemical when you have time to vacuum really well after it has clumped everything together. If your pool is just a little cloudy, we recommend using a clarifier first to see if that does the trick.

What is the next step after flocculation process?

Conventional plants separate coagulation (or rapid-mix) stage from flocculation (or slow-mix) stage. These stages are followed by sedimentation, and then filtration.

What is the purpose of flocculation during the treatment of drinking water?

Coagulation-flocculation is a conventional pre-treatment method (typically in combination with sedimentation] and rapid sand filtration) used to separate the suspended and dissolved compounds (turbidity) from the water in (semi-)centralised drinking water treatment plants.

What happens during the process of flocculation?

Applications Surface chemistry. In colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. Physical chemistry. Civil engineering/earth sciences. Biology. Cheese industry. Brewing. Water treatment process. Jar test.

How do flocculants work and why?

These two basic concepts are the reasons that flocculants work. When the particles come together, they get heavier . When they get heavier, the water molecules cannot push them around as easily as they used to, and gravity pulls them to the bottom of the water container. The result is water with less dirt in it!

What is the purpose of flocculant?

Flocculants , or flocculating agents (also known as flocking agents), are chemicals that promote flocculation by causing colloids and other suspended particles in liquids to aggregate, forming a floc. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles.

What is meant by flocculation power?

The coagulating power or flocculating power is the reciprocal of coagulating value or flocculating value. How do you find coagulating powers? So, according to this rule, greater the charge on an oppositely charged ion, greater is its coagulation power.
