Why is my floc not settling?

Table of Contents

Finely dispersed solids (colloids) suspended in wastewaters are stabilized by negative electric charges on their surfaces, causing them to repel each other. Since this prevents these charged particles from colliding to form larger masses, called flocs, they do not settle.

Why is my pool floc not working?

Floc can’t take care of live algae. All of the algae needs to be dead before you try to use floc. There are some other situations where floc might not work completely the first time, but they are far less common. The most common of the uncommon cases is probably not using enough floc.

How long does it take for floc to settle?

It just coagulates the tiny particles in the water so they can settle out or be filtered. It’s the last step after everything else is fixed. That being said, Floc takes 24-48 hours to settle out with the pump OFF.

Can you put too much floc in pool?

Flocculation refers to suspended particles in the water that give it a murky appearance. Flocculants are substances that help clear the cloudiness and restore the clarity to your swimming pool water. You can use too much floc, however.

What causes floc to float?

If the time in the flocculation tank(s) between pH adjustment and the clarifier is too short to allow these gas bubbles to detach from the floc particles and escape, they can collect in the clarifier to a sufficient size so as to cause floc or sludge particles to float to the top of the clarifier and out its overflow.

How can you improve settling in activated sludge?

Excess organic load can be remedied by reducing the waste-activated sludge rate by an amount less than 10 percent per day, to return to proper loading parameters and increase the returned activated sludge rates. About a 30 percent level of settled solids in the clarifier should be established and maintained.

Will floc work if pH is low?

Balance the pH level to about 7.0 Because flocculants can affect the pH level, you’ll want to start out with it at about 7.0 so you can make sure your sanitizer keeps working at maximum efficiency.

How do you vacuum a pool after floc?

Our Pool Floc Hot Tips

Floccing is best done in the evening: you can add the floc, run the pump for 2 hours, then leave it for 8 hours overnight and vacuum the next morning.
Vacuum slowly!
Usually while vacuuming to ‘Waste’, you can run the garden hose into the pool to keep the water level the same.

Does flocculant affect pH?

Because flocculants can affect the pH level, you’ll want to start out with it at about 7.0 so you can make sure your sanitizer keeps working at maximum efficiency.

What causes pin floc in water treatment?

What happens if MLSS is high?

If content is too high The process is prone to bulking of solids and the treatment system can become overloaded. This can cause the dissolved oxygen content to drop; this may reduce the efficiency of nitrification and the settleability of the sludge. Excessive aeration will be required which wastes electricity.

What causes pin floc?

Pin floc occurs most commonly at starvation conditions — a very low F/M and long sludge age. Chronic toxicity can also cause a pin floc condition. Free floating filaments can, at times, cause a dispersed growth problem. Here, the cause is filament-specific and is the same as for filamentous bulking (discussed below).

What happens if you add floc to your pool?

Here is the thing, after adding floc to your pool, you would experience a cloudy appearance in your water. In fact, in its natural form, floc will clump tiny particles together, which sinks down to the bottom of the pool, thus making your pool cloudy.

Why is my floc not working after floc?

Flocculant not working – Pool still Cloudy after Floc! Even after adding a pool flocculant to the water, you might still see some cloudiness in it. This can be due to the any of the following reasons: Imbalances in the free chlorine (FC) levels.

Why is my pool still cloudy after floc?

What is a pool flocculant?

Often simply called a pool floc, a pool flocculant is a chemical that is added to the pool water to clump together the microscopic pieces of dirt into larger clumps that can be removed at the bottom of the pool.
