Water Distillation Principles
--------------------------------------------------------------------------------
Every element can exist in three states: as a liquid, as a solid and
as a vapor, which mostly depend on it's temperature. This applies to
water, too. So, water can be found as ice, water and steam. If water
is cooled down below 0 degrees Celsius (32 Fahrenheit), it becomes
ice, and if heated above 100 degrees Celsius (212 Fahrenheit), it
becomes steam. The temperature, at which a substance changes it state
from liquid to vapor is called a boiling point, and it is different
for different substances. This difference can be used to separate
substances, and as such can be used for water purification.
The process is relatively simple:
a) the dirty water is heated
b) to the boiling point and thus vaporizes
c) (becomes steam), while other substances remain in solid state, in
boiler. Steam is then directed into a cooler
d) where it cools down and returns to liquid water
e) and the end result is a water, purified of additional substances
found in it before distillation.
Distillation is an effective process and, what's more important, it
can be done with a lot of improvisation. You can heat water with
whatever is at hand: fire, electricity, or whatever. You can use
almost anything that holds water for a boiler, as long as you can
direct the steam into a cooler. A cooler can be a long piece of
copper tubing bent into a spiral. All you need is something that will
just cool the steam down. In a worst case scenario, you can distill
water with an ordinary household pot and two pot lids. Boil water in a
pot covered with the first lid. After a while, you'll see that the
water in the pot vaporizes, and condenses on the lid (this is
distilled water). Now replace the lid with the second lid, and turn
the first one vertically, so that all condensed water collects at one
point, and then pour it into a cup. Meanwhile, more distilled water
condenses on the second pot lid, so just repeat the above steps
again... until you have a full cup.
Distillation will remove from water almost anything, even heavy
metals, poisons, bacteria and viruses. However, it does not remove
substances that have boiling points at a lower temperature than water.
Some of these substances are oils, petroleum, alcohol and similar
substances, which in most cases don't mix with water. Also, remember
that substances removed from water remain in the boiler, so you'll
need to clean it up every once in awhile.
Distilled water can be used directly and does not need to be boiled
again. As it is already hot, you can use it to prepare tea, or similar
drinks.

prolonged use of only distilled water can leech minerals from your body , be aware of this .
there is reason that drinking distilled water is used as a remedy for kidey stones at times ....
