WebMar 19, 2024 · Sedimentation is the 3rd step in a conventional treatment process. It occurs after coagulation and flocculation and before filtration. Sedimentation removes suspended solids with the use of gravity by slowing the flow of water down to allow material to settle. WebJun 9, 2024 · Rocks as small as tiny clay particles and larger that are moved by the water are called sediment. Fast-moving water can pick up, suspend, and move larger particles more easily than slow-moving waters. This is why rivers are more muddy-looking during storms—they are carrying a LOT more sediment than they carry during a low-flow period.
