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 the use 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 are the benefits of flocculation?
Coagulation and flocculation are used to remove colour, turbidity, algae and other micro- organisms from surface waters. The addition of a chemical coagulant to the water causes the formation of a precipitate, or floc, which entraps these impurities. Iron and aluminium can also be removed under suitable conditions.
Why do you floc a pool?
Pool floc binds particles (and dead algae) that are making your water cloudy together and sinks to the bottom of your pool so you can easily vacuum out the cloudy mess.
When should I use floc in my pool?
Flocculant, or pool floc as it’s sometimes called, is a chemical that you add to your pool when other methods of clearing it up aren’t working. The flocculants clump together floating particles in the water that are too small and light to sink to the bottom to be vacuumed up.
How fast does flocculant work?
Flocculant, although fast-acting, will still need around 8-16 hours to work its magic. It’s easiest to do this overnight. The pump definitely needs to be off as you want the water to be still. The floc will have settled at the bottom of the pool and will require manual vacuuming to remove the debris.
How does a flocculant work?
A flocculant is a chemical that can be added to the water to help colloids and any other suspended solids bind together and form heavier particles. The heavier particles then settle to the bottom of the container/tank and the water on the top is drained off.
How can flocculation be prevented?
When particles of a suspension come close together they can form aggregates called flocculates which will settle more rapidly. To prevent that we often coat the particle with a charged surfactant. The charge (Zeta potential) acts to keep the particles separate and prevent flocculation.
What is the meaning of a flocculant?
flocculant. / (ˈflɒkjʊlənt) / noun. a substance added to a suspension to enhance aggregation of the suspended particles.
What two chemicals are commonly used as water coagulants?
Aluminum sulfate (alum) is the most common coagulant used for water purification. Other chemicals, such as ferric sulfate or sodium aluminate, may also be used.
Can you put too much floc in pool?
Too much floc can detract from the beauty of your pool. Without proper care, swimming pool water can turn cloudy and change color. Flocculation refers to suspended particles in the water that give it a murky appearance.
How do I make my pool water crystal clear?
So the best way to have a crystal clear pool is prevention. Keep the chemical levels within the ideal ranges. Check the flow meter to be sure the pool is circulating water at a proper flow rate. Brush the walls and floor weekly. Keep a preventative amount of algaecide in the pool.
Can you swim after adding flocculant?
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.
Can you use flocculant and shock at the same time?
Answer: Shock can be added at any time. Especially since you are treating a green pool. The hot sun can tend to burn off chlorine faster, but the green pool needs to be treated and the sooner, the better. The chlorine will remain high for a few days after shocking anyway whether or not the sun is out.
How long can pool water go untreated?
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
Why does my pool get cloudy when I vacuum?
Low chlorine level is the primary cause of cloudy water. If all the chemicals are balanced, but water is still cloudy, there might be fine particles inside the pool, and you need to use a clarifier or pool flocculant and then vacuum up the pool. If all do not work, try backwashing your filter since it might be clogged.
Can I use clarifier after flocculant?
Do you use Clarifier in conjunction with Flocculant? Flocculant can be used after clarifier. However, using too much of any product can work against the clarifying process.
Will clarifier clear a green pool?
ADD POOL CLARIFIER The change in your pool water colour means that you have successfully eliminated the algae and can now clean it out of your pool. If your water is still green, wait another 24 hours and redo the steps from Days 1 and 2. This may take up to a few days for very cloudy pools.
Can you use flocculant with a cartridge filter?
3. Use Pool Flocculant (Floc) A chemical known as flocculant, or floc, is a good idea if you’re in a rush, or would like to see your swimming pool water cleared quickly. Again, flocculant should be avoided if you are using a cartridge filter as it will clog the paper pleats.
What is the difference between flocculant and coagulant?
Coagulation is a chemical process. Flocculation is a physical process. Coagulants such as inorganic salts of aluminum or iron that neutralize the suspended particles are added during coagulation. Flocculant such as an organic polymer that involves in bridging and strengthening the flocs is added.
Is flocculant and clarifier the same thing?
The main difference between the flocculant and pool clarifier is where the clumped particles go. You can also leave the pool filter off overnight while the pool floc goes to work, which is one less thing to do. Flocculant also works much faster than the pool clarifier.
Can you drink flocculant?
In addition, coagulants and flocculants are expensive, which is why you want to avoid adding more than are necessary to the water; drinking water treatment plants use “jar tests” to identify the optimal coagulant and flocculant concentrations. Do not drink any of your water samples—even if they appear clear.
