Final answer:
The typical process for purifying municipal drinking water involves filtration to remove particles, flocculation to clump together particles for easier removal, and chlorination for disinfection. The correct sequence of purification steps is filtration, flocculation, filtration, and chlorination.
Step-by-step explanation:
The steps in the typical purification processes for municipal drinking water involve several stages to ensure that water is safe for consumption. These stages typically include:
- Filtration: This process involves passing the water through layers of sand, gravel, and charcoal to remove small particles.
- Flocculation: This step involves the addition of chemicals to the water that causes small particles to clump together into larger particles, known as flocs, which can then be more easily removed.
- Disinfection: After filtration, the water is typically disinfected, often using chlorine, to kill any remaining bacteria and germs.
Therefore, the correct sequence of steps from the options provided is C: filtration, flocculation, filtration, and chlorination.
