Desalination: Distillation and Reverse Osmosis | GCSE
Desalination is the process of removing salt from sea water to make it potable.
What is a major disadvantage of using desalination to get fresh water?
What is Desalination: Distillation and Reverse Osmosis | GCSE?
"The process of removing salts and other minerals from saline water."
What is potable water?
Where do the potassium salts for NPK fertilisers come from?
Which catalyst is used in the Haber Process?
What is the very FIRST stage typically considered in a Life Cycle Assessment?
Salt Removal
Distillation: Boiling water and condensing the steam to leave salt behind.
Reverse Osmosis: Forcing sea water through a membrane at high pressure.
Both processes require a lot of energy and are expensive.
Necessary in countries where fresh water is scarce.
Energy Tip: Because desalination is so power-hungry, it is often only used when fresh water sources aren't available.
