Basically, desalination of water can be carried out by the following general methods:
1. Distillation
2. Electrodialysis
3. Demineralisation/Deionisation and
4. Reverse osmosis.
ice
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.
Yes. Desalinization is a redundant and incorrect form, so desalination only should be used.

Desalination
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.
The ice caps are made of freshwater.
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
Sea water desalination
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.
Desalination of sea water
Those near sea water get water from desalination systems. Those further inland melt ice for water.
