How does flocculation purify water
Once the flocs have settled to the bottom of the water, the clear water on top is filtered to separate additional solids from the water. During filtration, the clear water passes through filters that have different pore sizes and are made of different materials (such as sand, gravel, and charcoal). These filters … See more Coagulation is often the first step in water treatment. During coagulation, chemicals with a positive charge are added to the water. The positive … See more Flocculation follows the coagulation step. Flocculation is the gentle mixing of the water to form larger, heavier particles called flocs. Often, … See more After the water has been filtered, water treatment plants may add one or more chemical disinfectants (such as chlorine, chloramine, or … See more Sedimentation is one of the steps water treatment plants use to separate out solids from the water.

In colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float to the top of the liquid (creaming), settle to the bottom of the liquid (sedimentation), or be readily filtered from the liquid. Flocculation behavior of soil colloids is closely related to freshwater quality.
