- 21DecantationSeperation by pouring liquid off the top of a mixture of solid in liquid, or liquid in liquid
- 22DesalinationRemoving dissolved salts such as sodium chloride from water
- 23DistillationA process that uses evaporation and condensation to seperate solids from liquids, enabling the recovery of both
- 24FiltrateLiquid that passes through the filter paper
- 25FiltrationSeperation of solids or liquids from a liquid or gas by using a barrier with holes smaller than the particles being seperated
- 26Gravity SeperationA method of seperating two components from a suspension by using the force of gravity to seperate heavier particles to the bottom

- 28ImpuritiesUnwanted substances
- 29Potable WaterWater that is drinkable
- 30ResidueSolid left in the filter paper after filtration
