Water Purification

Once a water source has been obtained, depending on how safe this water is, it may need to be purified.

There are a lot of methods to do this. Most are mentioned on Wikipedia - Water purification.

Distillation

From Wikipedia:

Distillation involves boiling the water to produce water vapour. The vapour contacts a cool surface where it condenses as a liquid. Because the solutes are not normally vaporised, they remain in the boiling solution. Even distillation does not completely purify water, because of contaminants with similar boiling points and droplets of unvapourised liquid carried with the steam. However, 99.9% pure water can be obtained by distillation.

Distillation is an easy method to sterilise and remove most contaminants from the water. There are a number of methods of distilling water.

Traditional Distillation

Involves heating the water in a vessel to boiling point and collecting the vapour in a condenser.

Solar Distillation

Uses the sun as the heat source to vaporise the water. The easiest way of doing this involves building a greenhouse type structure as shown below.
