Multi-Stage Flash purification. (MSF)

multi-stage flash is when you heat sea water. in a sealed container, with an opening at the top leading to a seperate container next to it. this means that the pure water boils off and runs down into the seperate container, leaving the salt alone at in the first container.

in the newer containers, the pressure is reduced so that water boils at a lower temperture, so it takes less energy to heat the water to the boiling point.
