What do sedimentation processes promote?

Sedimentation processes are essential in water treatment because they utilize the principle of gravity to separate solid particles from water. During sedimentation, the water is allowed to sit in a large basin or tank for a specific period of time, during which heavier solid particles gradually settle to the bottom due to the force of gravity. This settling process effectively reduces the concentration of suspended solids in the water, leading to clearer water that can be subsequently treated or released.

This method does not rely on temperature increases, filtration methods, or the coagulation of dissolved solids, as these processes involve different mechanisms. Filtration specifically targets smaller particles and microorganisms, while coagulation involves the agglomeration of smaller particles into larger ones for easier removal, typically followed by sedimentation. Understanding sedimentation is crucial in designing both efficient and effective water treatment systems.
