Answers
Answer:
The working of the water treatment plant.
Explanation:
The four major steps in the water treatment plant are as follows :
1) Flocculation: This is the first step in water treatment. Chemicals with high electron affinity are added to the water. The chemicals neutralize the negative charge of the dirt and other dissolved particles in the water. When this occurs, particles bind with the chemicals to form large particles, called floc.
2) Sedimentation: During sedimentation, floc settles to the bottom of the water supply due to its weight.
3) Filtration: After sedimentation, the clear water is passed through the filters made of sand, gravel, and charcoal to remove dissolved particles, such as dust, bacteria, and chemicals.
4) Disinfection: After filtration, a disinfectant like chlorine or chloramine may be added to kill any remaining bacteria, viruses, and parasites.
