What process follows flocculation in water treatment?

• A. Filtration
• B. Chlorination
• C. Sedimentation
• D. Coagulation

Answer: (C)

After the flocculation process in water treatment, the next step is sedimentation. During flocculation, smaller particles in the water are agitated and come together to form larger clusters called flocs. Once these flocs have formed, the water is allowed to sit undisturbed in a sedimentation basin. In this quiet environment, the larger flocs settle to the bottom of the basin due to gravity, separating them from the clearer water above. This sedimentation step is crucial because it effectively removes a significant portion of the suspended solids, making the water clearer and cleaner before it proceeds to the next stages of treatment, such as filtration or disinfection. Understanding the sequence is essential for efficient water treatment and ensuring that each stage adequately prepares the water for safe consumption.
