Q: In a sedimentation tank:
  • A. Surface area is of more importance than capacity
  • B. Depth is more important than surface area.
  • C. Capacity his more important than surface area.
  • D. Surface area, capacity and depth are equally important.
Correct Answer: Option A - In the sedimentation tank, remove suspended soils. The length of the sedimentation tank should be such that the particles of impurities sit on the bottom of the tank. The surface area for sedimentation in the sedimentation tank is more important than the capacity of the tank. The flow of water in the sedimentation tank is 500 L for normal water.
