Flocculation

Flocculation is when tiny particles stick together to form big clumps.

Think of it like making a tower with Lego bricks. You start with a lot of small Lego bricks and then you stack them on top of each other to make a big tower.

In the same way, flocculation is when small particles, like dirt or bacteria in water, stick together to form big clumps. These clumps are easier to see and remove from the water.

Flocculation is often used in water treatment plants to clean dirty water. Chemicals are added to the water to help the particles stick together and form larger clumps. Then the large clumps settle to the bottom of the tank or are filtered out, leaving the water cleaner and safer to use.

So, basically, flocculation is like building a tower of Legos with tiny particles in water, so they can be easily removed and cleaned.
