Separation by density relies on differences in mass per unit volume. Denser materials settle at the bottom or move outward in a centrifuge, while lighter materials remain on top or at the center.

Filtration purifies water by passing it through a filter medium that traps impurities, such as particles and microorganisms. The filtered water, free of these contaminants, is then collected for safe use.
Simple distillation is used for separating liquids with significantly different boiling points, while fractional distillation is for liquids with closer boiling points, using a fractionating column to improve separation efficiency.
Sedimentation plays a crucial role in water treatment by allowing solid particles to settle at the bottom of a tank, thereby removing suspended contaminants and clarifying the water for further purification.
A separating funnel allows efficient separation of immiscible liquids based on density differences. It provides precise control over the separation process, making it useful for separating mixtures like oil and water.
