Basically, desalination of water can be carried out by the following general methods:

1. Distillation

2. Electrodialysis

3. Demineralisation/Deionisation and

4. Reverse osmosis.

When is physics used in desalination?

Physics is used in desalination when understanding processes like osmosis, reverse osmosis, and thermodynamics, which are fundamental to desalination technology. These processes involve the movement of water across membranes under pressure differentials and the utilization of energy for separation, making physics a critical aspect of the desalination process.


Are desalinization and desalination interchangeable words?

Yes. Desalinization is a redundant and incorrect form, so desalination only should be used.

What is the name of the process used to remove salt from seawater?

Desalination. There are two methods ;- Boiling the salt water to collect the steam and condense it. This is expensive at it involves the costs of heating. Osmosis; the salt water is placed to one side of a semi-permeable membrane. The water molecules are small enough to pass through the membrane, leaving the larger salt molecules behind. This is a much cheaper method as it does NOT involve in the costs of heating. It is the preferred method in dry/arid/desert climates for producing fresh water from sea(salt)-water. In places like Saudi Arabia or Chile(Atacama Desert), desalination plants are usually found in industrial areas adjacent to the coast.


Why does the melting of the ice caps lower the concentration of salt in the ocean?

The ice caps are made of freshwater.


Why isn't desalination used more?

Desalination isn't used more often because it cause's a waste stream called brine and the discharge of chemicals and all that waste can affect the marine life

How does freezing desalination work to produce fresh water from seawater?

Freezing desalination works by freezing seawater and separating the ice crystals from the remaining saltwater. The ice crystals are then melted to produce fresh water, while the saltwater is left behind. This process helps remove salt and impurities from seawater, resulting in fresh water that is safe for consumption.
