But how does flocculation works? What are the different types of flocculants ? How to use flocculants properly In this article, discover all the answers to the questions you may have about the principle of flocculation.


What is a pool flocculant?

Used to complement the filtrationfiltration flocculant products are maintenance products capable of cleaning and depolluting water in the blink of an eye. To this end, the flocculent acts as an agglomerate: when it comes into contact with the microparticles present inside the basin, the flocculent product will transform into so-called “flakes” around which suspended particles will cling, agglomerate and coagulate. These flakes are then filtered and eliminated more easily by the filtration system. Your water regains its natural crystallinity.

This chemical treatment is particularly recommended when the filtration system has difficulty filtering out fine particles and the water becomes cloudy. This is the case, for example, when you make a anti-algae shock treatment with chlorine or bromine.

Depending on the filtration system used, there are two main types of flocculant types of flocculant :

Liquid flocculants

Reserved for ponds equipped with a sand filterfilter liquid flocculants for pools are renowned for their speed of action. These are often used after a shock treatment for healthy, clear water almost immediately.

Before pouring the product into the pond water, be sure to read the instructions for use. To avoid unpleasant surprises, it’s best to follow the manufacturer’s instructions on recommended dosages. These are calculated according to the number of cubic meters of water in the pool.


Cartridge flocculants

In contrast to flocculants in tablet or liquid formThis system allows slow diffusion and permanent treatment. Once deposited in the skimmer basket (or in your pool’s buffer tank), the flocculation action starts as soon as water enters the filtration system.

In this way cartridge flocculants are ideal for preventive use, when the water is naturally cloudy and the filter no longer achieves sufficient efficiency. In fact, it acts as a kind of complementary treatment to that used on a regular basis. Please note that this solution is not suitable for pocket filters nor cartridge filters. It is reserved exclusively for sand filters !

Finally, watch out for overloading of your filter: to avoid this, you’ll need to be vigilant and clean it regularly.

How to use pool flocculant

For successful flocculation and pool maintenanceIt is important to scrupulously respect the dosage indicated on the product. Please note, however, that this will depend on the type of flocculant and the reason for its use.

As a guide, for routine maintenance, you should pour in approximately 10 ml of liquid flocculant/1 m3 once a week. If you use cartridge flocculantIf you use a cartridge flocculant, you’ll need to place one in your pool’s skimmer or buffer tank every 15 days.

But dosage is not the only thing to check if you want successful flocculation of your pond. For everything to go smoothly, it is important to follow these few recommendations:

– Check that the pH of the pool is between 7 and 7.4. Readjust if necessary;

– Before using flocculant, switch off the pool pump and read the instructions carefully;

– Clean the filter and set the filter valve to “circulation” so that no more water passes through the filter. This will prevent clogging;

– Once the product has been administered, activate the pump for a few hours to ensure that the water is properly stirred;

– Stop the pump for 24 hours to allow the flocculant to take effect. Agglomerated residues will begin to fall to the bottom of the pool;

– Set the filter valve to “filtration”, start the pump and clean the bottom of your pond with a vacuum cleaner.


How do I remove a pool flocculant?

Is your pool water still cloudy despite the use of flocculant? You may have administered too much flocculant in the poolcausing an overdosing. In this case, there’s no point in adding more product to the pool, as this will only make the problem worse.

Conversely, stop using the flocculant immediately and wash (or replace) your pool filter. For 24 hours, also turn off the filtration system to allow the product to settle to the bottom of the pond.

Then vacuum up the flocculent deposit using a vacuum cleaner. vacuum cleaner or ahand broom. Do not use your pool cleaner for this operation, as this could scatter the particles all over your pool.

In addition, you can use a clarifying product for crystal-clear water.

If, despite your best efforts, the water remains cloudy for several days, you may need to call in a professional. For more information, please contact our Aboral team.
