Sedimentation - North Texas Municipal Water District

Sedimentation is a physical water treatment process that uses gravity to remove suspended solids from the water. Coagulation. Typically we start by adding ferric sulfate to the water, which attaches to the very fine particles that make up the suspended solids in the raw water. Once attached, they begin to coagulate (or clump together).

Climate Adaptation and Erosion & Sedimentation | US EPA

May 26, 2021· Increased sediment and erosion in rivers, lakes and streams can also affect water quality and availability of drinking water sources. For example, increased sedimentation can affect the storage capacity of reservoirs and increase the need for treatment at water utilities.

Sedimentation and Erosion - Yellowstone National Park (U.S ...

Oct 03, 2016· Agents of erosion— wind, water, ice, and waves—move weathered materials from one place to another. When erosion takes place, sedimentation—the deposition of material—also eventually occurs. Through time, sediments are buried by more sediments and the material hardens into rock.
