    1. Answer: b
      Explanation: Mechanical method of water treatment involves sedimentation and filtration. During sedimentation water kept at standstill or flow with a very low velocity which causes the solid matter to settle down and finally removed. During filtration the dirty water is allowed to flow downward through the beds of filtering materials to remove suspended matters.
