Solution

The correct option is D Sedimentation
Sedimentation is the first step performed in the purification of river water. River water is pumped into tanks, basins or reservoirs and left standing for few hours. Suspended particles such as clay, stones and silt settle down. The suspended particles settle down at the bottom as sediments. The rate of sedimentation can be increased by adding potash alum.
