What does "flocculation" achieve in water treatment?

• A. Increases alkaline levels
• B. Reduces temperature of water
• C. Forms flocs to remove suspended particles
• D. Enhances water taste

Answer: (C)

Flocculation is a critical process in water treatment that involves the formation of flocs, which are clumps of particles that come together to form larger aggregates. This is primarily achieved by adding chemicals called coagulants to the water, which destabilize the particles and promote their aggregation. Once these particles cluster together into larger flocs, they can be more easily removed from the water during subsequent treatment processes, such as sedimentation or filtration. The formation of flocs is essential for effectively removing suspended solids, colloidal materials, and other impurities from the water, thereby improving its clarity and quality. This process is particularly important in the treatment of surface water sources where a significant amount of particulate matter may be present. By forming flocs, flocculation streamlines the overall purification process, making it more efficient in delivering clean and safe drinking water. Other options do not accurately represent the primary function of flocculation. While water chemistry and taste may be indirectly impacted by overall treatment processes, the core activity of flocculation is specifically to aggregate and remove suspended particles, making the formation of flocs the key achievement of this process.
