Sedimentation is the process by which solid particles settle out of a liquid or gas and come to rest on a surface. This can occur naturally in bodies of water, such as rivers and oceans, as particles sink to the bottom over time. Sedimentation can also be used in various industrial processes, such as wastewater treatment and mineral processing, to separate solids from liquids. Research in sedimentation aims to better understand the factors that influence particle settling, improve sedimentation processes, and develop new technologies for separating particles efficiently and effectively.
