7. DISTILLATION

8. Freeze Distillation
Freeze distillation depends on the fact that water with salt freezes at a lower temprature than does fresh water. So as we freeze salina water, ice that forms on the top is actually purer water.
This process may be repeated several times to gain purer water.

9. Flash Evaporation
In flash distillation,large quantities of salina water heated in pressure champers to beyond the boiling point.
The superheated water is then introduced to a low pressure vessel, where it “flashes” in to steam.
This steam-still superheated-helps to heat the water in the pressure champers on its way to be condensed as pure finished water.
