Coagulation and Flocculation
Chemicals with a positive charge are added to the supply of water that’s being treated—these neutralize the negative charge of other things in the water like dirt and other dissolved particles. These particles then bind with the added chemicals to form larger particles, called floc.
Sedimentation and Filtration
The floc, or larger particles, eventually settle to the bottom of the water supply, leaving only the clear water on top.
Disinfection
After the water has been filtered, a strong disinfectant like chlorine or chloramine may be added to kill any addition parasites, bacteria, or viruses. The chemicals added at this stage of the treatment process also supply an extra layer of protection to the water for when it’s eventually piped into homes and businesses.
