B. remove particles that are more dense than water
C. remove the pertinacious material from the water
D. none of the above

Answer 1

Sedimentation is a physical process used in wastewater treatment to

• A.remove particles that are less dense than water

Answer 2

Sedimentation is a physical process utilized in wastewater treatment to remove particles that are denser than water.

Sedimentation is the method involved in separating tiny particles and silt in the water. This interaction happens normally when water is still since gravity will pull the heavier particles down to shape a slime layer. Nonetheless, this activity could be artificially invigorated in the water treatment process. This mechanical help is called thickening.
