Separation of solid suspended in liquid into a supernatant clear liquid and a denser slurry employs a process termed as the___________________?
Correct answer: C. Sedimentation
- A. Coagulation
- B. Flocculation
- C. Sedimentation
- D. Clarification
Explanation
Sedimentation uses gravity to separate a suspension into a clear supernatant and a concentrated, denser slurry. Clarification emphasizes recovery of the clear liquid, but the general separation operation described here is sedimentation.
