Water purification process:

Sedimentation

The sedimentation process is where all of

the little pieces of sediment sink to the bottom of the container.

Filtration

This is where the floc (little pieces of

sediment) is filtered out through a filter.

Chlorination

Safe levels of chlorine are added, and it

kills all the bacteria that is still in the water.
