Which statement correctly describes ATS processing?

• A. They are used to increase water flow rate.
• B. They facilitate coagulation, flocculation, and filtration by adding chemicals.
• C. They remove birds from the site.
• D. They are only used for odor control.

Answer: (B)

ATS processing relies on adding chemicals to treat water so that contaminants can be removed more effectively. The key idea is that coagulants neutralize the electrical charges on particles, letting them come together; then flocculants help these particles form larger clusters called flocs. Once these flocs are large enough, filtration can physically remove them from the water. This sequence—chemical addition to promote coagulation, followed by flocculation to grow particles, and finally filtration to remove them—is what ATS processing does. This isn’t primarily about increasing water flow rate, removing birds from a site, or odor control. Those are unrelated goals.
