7. Wastewater Treatment Plant

8. There are six steps to wastewater treatment……
First Filtration
Coagulation
Sedimentation
Second Filtration
Disinfection
Storage

9. Step 1: First Filtration
Wastewater passes through a screen or filter that separates out larger solid materials

10. Step 2: Coagulation
A chemical (alum) is added to water to cause dirt and other particles to clump together. The clumps are called floc.

11. Step 3: Sedimentation
The heavy particles (floc) settle to the bottom.

12. Step 4: Filtration
The water passes through filters made of sand, charcoal, and gravel to help remove smaller particles.

13. Step 5: Disinfection
A small amount of chlorine is added to water to kill bacteria.

14. Step 6: Storage
The water is stored in a tank until the community needs it again.
