Sedimentation is a fundamental process used in stormwater treatment to remove pollutants from runoff. It relies on gravity to deposit suspended sediment and debris into a designated settling area for later removal. Many pollutants that adhere to solids, such as metals, phosphorus, and hydrocarbons, are also removed through this process.
