What are Flocculants?

Flocculants

Flocculation is referred to the separation of a solution and is commonly used to describe the removal of sediment from a fluid. In addition to occur naturally, it can also be forced through agitation or the flocculating agents. There are many manufacturing industries that use it as part of their processing techniques as well as extensively employed it in the water treatment.

 

This technique is widely used in the medical world to analyze various fluids. The tern is derived from floc which is another word for flakes of material and when a solution is flocculated, the sediment will form into clumps of aggregate that are easier to see. This is initiated intentionally as the floc is usually removed with screens or filters. The solution is separated by accidents and attempts to turn it back into a solution so that it will be usable again.

 

This technique can be used to separate out the visible materials and sediments as well as to treat colloids. Colloid is a solution that looks uniform but consists of one or more components blended together. The most common of solutions with visible sediment are wastewater and swimming pools. Both are flocculated for purity and are frequently encountered with colloids which include glues, milk, inks and sea foam.

 

The separated elements within the colloid are thoroughly blended to create a new compound and they can be separated again. However, depending on the circumstances whether flocculation is desired or undesired and can often deliberately achieved in the treatment of wastewater by removing harmful substances so that they can be treated separately.

 

For instance, deliberate processing can include grease traps in commercial kitchens and centrifuges for processing blood as well as facilities for extracting salt from the seawater. If in the case of undesired flocculate is soured milk which the milk colloid separates by forming a layer of flakes of material on top. If this separation is not desired in a manufacturing environment, these steps are taken to minimize it.

 

There are number of ways to separate a solution and agitation is one common technique. It can encourage flakes of sediment to clump together and gather on the top or bottom depending on their weight. Flocculants chemicals are also used to encourage clumping in a solution that is typically different electrical charge than the substances being precipitated out of the solution such as attracting the material in clumps of particles.
