Decanting and centrifuging to separate solids from liquids
Hospitals may use centrifuges to separate blood cells from the liquid
part of the blood before they do a blood transfusion
Liquids can be separated from more dense solid materials by decanting.
If the solid substance is allowed to settle at the bottom of the
container, the liquid at the top can then be poured into a separate
A centrifuge  is a more powerful way of achieving the same result.
Centrifuges are used to separate solids that would not normally settle
through the action of gravity alone.
