The great thing about using a still, or in this case, a solar still to purify water is that any water source can be used, even dirty unfiltered water and sea water!
Boiling water is the most common way to purify water to make it safer to drink. The problem is that boiling dirty water with debris in isn’t very effective as even after the water is boiled, there is still potentially dangerous sediment and debris in the water. It is the same with salt water, boiling won’t make it drinkable… Purifying water with any still and in this case a solar still, will effectively purify both dirty unfiltered water and salt water. This is because in both cases, the sediment and salt etc, don’t evaporate, so they are left behind to be discarded.
