Answer:
Sedimentation refers to the process of settling or deposition of solid particles suspended in a liquid or gas. It occurs due to the force of gravity acting on the particles, causing them to settle down and form a sediment at the bottom of the container. Sedimentation is commonly used in various industries such as water treatment, mining, and wastewater treatment.
Decantation, on the other hand, is a separation technique that involves pouring off a liquid from a mixture without disturbing or transferring any sediment or solid particles present at the bottom. It is often used to separate a clear liquid from a mixture containing suspended solids or immiscible liquids.
