What is added to water to cause flocculation?
A flocculant, such as alum or polyacrylamide, is added to water to cause flocculation. These chemicals help to aggregate suspended particles in the water, making them easier to remove through filtration or settling processes.
What is flocculation?
Flocculation is one step in the water and wastewater treatment process. In a flocculation tank, the water is stirred or otherwise moved around so that the particles move around, bump into other particles, and stick to one another. Eventually the small and difficult to remove particles in the water form large clumps which can then be easily removed. Chemicals (most commonly "alum") are often added to the water going into a flocculation tank to help aid particle formation.
How very fine solid particles are removed from water in a water treatment plant?
The very fine particles present in a water treatment plant are often the clays - materials that used to be rock or sand, but now well decomposed from their original form. Clays may be removed by precipitation - by binding them with lime, which reacts with them to form a flocculant. A material that now occupies a greater volume, and will settle out for further treatment by simple filtration.
What is difference between flocculation and precipitation?
PrecipitaionLets take protein in water as a solution as an example. Protein consists of hydrophobic amino acids and hydrophilic amino acids. Hydrophobic amino acids are usually seen in the protein core and hydrophilic aminoacids forms hydrogen bond with water molecules. When an organic solvent, or salt is added to the solution water molecules which are in hydrogen bond with the hydrophilic amino acids break the bond and binds with the salt or solvent. Thus protein protein interaction becomes stronger than protein -water interaction. So due to partial dipole interaction and electrostatic force of attraction protein molecules aggregate and precipitate.FlocculationConsider a solution of proteins. If the solution is agitated continuously the protein molecules come together. If the agitation is that stronger effect to overcome the electrostatic force of repulsion between the protein molecules, they will cling together and forms floc. Another method is adding chemicals called flocculants. By adding floculants the electrostatic repulsion between the protein molecules can be reduced and this will lead to attraction of protein molecules and formation of floc.
What Mixtures are by comparing the sizes of particles in them?

What is floc in refrigeration oils?
Floc in refrigeration oil is wax that has separated out from oil containing parathene.
Is floc dangerous if consumed?
No, floc is not dangerous if consumed in small amounts. It is commonly used in water purification processes and is generally considered safe. However, ingesting large amounts of floc could potentially cause stomach discomfort.
Your pool does not have a to waste pump function. How do you get rid of the floc stuff on the bottom of your pool?
(Note : "floc" is the flakes that come out of colloidal suspension of pool chemicals.) You need to vacuum the floc from the bottom. However if you can't set your pool to waste, you can disconnect the pump hose from the pool and run it normally.
What is flocs?
Floc is the precipitant when s solute comes out of solution
Does activated sludge form a lacy network of floc mass that entraps many materials not used as food?
Yes, activated sludge forms a lacy network of floc mass that can entrap various materials, including not only food sources but also non-biodegradable substances and inert particles present in the wastewater. This entrapment allows for the removal and treatment of these materials during the sludge treatment process.
What is the floc or pour point of refrigeration oils?
Floc point, also known as Freon floc point, is used to measure the performance and consistency of refrigeration oils. In order for the refrigeration system to function properly, the oil used should be compatible. Wax can separate when an oil solution is cooled with Freon. Once the wax is separated it is called flocculation and that is the reason it is called floc point.
How does a flocculating agent work?
A flocculating agent works by causing particles in a solution to clump together, forming larger aggregates that can be more easily removed by filtration or settling. This process helps to clarify liquids by removing suspended solids or colloidal particles. Flocculating agents are commonly used in wastewater treatment and purification processes.

The pressence of Pin floc and a rapidly setting sludge are indicators of what in waste water?
The organism such as protozoan and rotifers.
What are the stages that water has to go through to be clean?
For drinking water the basic stages are1. Containment where water is pumped or directed from its source to a holding place.2. Screening where debris and large particles are removed.3. pH adjustment if the water is very acidic or alkaline4. Flocculation to remove turbidity (cloudiness) and clarify the water.5. Sedimentation to allow the floc to settle out6. Filtration to remove any remaining suspended particles and unsettled floc.7. Disinfection by filtering out microbes and adding chemicals to fill pathogens which pass through the filters.8. Fluoridation to add fluoride (in many places)9. Conditioning to reduce water hardness (if required)
Why is my pool cloudy?
Any particles in your pool can cause cloudiness - for example, dead algae. To eliminate it, most pool stores sell a "clarifier" - the one I sell is blue - which will get the particles out of your pool, or "alum" or "floc", which will bind the particles together, making them heavier, dropping them down to the bottom of your pool. You can then vacuum them out with your filter set to waste. If you have a DE filter, and you add a white powder to your skimmer sometimes, it is possible that your filter is leaking DE back into your pool and you need to replace the grids inside it.
What are floc agents for swimming pools?
A floc agent is a chemical used for floccing a pool. Flocculation is the process of clumping up the solids in the pool water and any chemical in solution. The 'floc' will eventually sink to the bottom so that it can be vaccumed to waste. Commonly used in new pool start up procedures after pool is initially filled with water
