This document discusses various methods of water purification and identifies the most appropriate methods based on different situations. It identifies boiling, filtering, distilling, and chlorination as common purification methods. Distilling is considered the most effective as it removes the widest range of contaminants, but has limitations as it removes minerals. The appropriate method depends on factors like local water quality, cost, and performance of the system. Groups will present creative ways to purify water and discuss limitations of distilling.

4. What is water purification?What is water purification?
Water purification is the transition of dirty
harmful (Contaminated) water into clean safe
water.

5. WHY PURIFY WATER?WHY PURIFY WATER?
We purify water to get rid of contaminants that
can be detrimental to our health.

6. What Is Water Purification?What Is Water Purification?
Water purification generally means freeing water
from any kind of impurity it contains, such as
contaminants or micro organisms.

7. Water purification, or drinking water
treatment, is the process of removing
contaminants from surface water or
groundwater to make it safe and palatable for
human consumption.

13. Which Method is Appropriate?
There are various methods of water
purification and filtration, some more effective
at removing certain types of contaminants
than others.

14. Which Method is Appropriate?Which Method is Appropriate?
Whilst there are contaminants in every water
supply, the methods of water purification and
filtration you'll use will depend on 3 things:
(1) the state of your local water supply;
(2) the cost and performance of the filtration unit
and
 (3) their health-benefits.

15. BoilingBoiling
The general advice is to boil all water for 5-10
minutes plus 1 minute for every 300m above sea
level, up to around 5500m where boiling becomes
ineffective.

16. FilteringFiltering
Some home water filtration
systems can remove chemical
contaminants for example,
but fail to effectively remove
microbiological ones
(bacteria) from your water
supply. Therefore, these are
not "purifiers" in the true
sense of the word.

17. DistillingDistilling
Of all the methods of water
purification and filtration,
distillation is considered in
some quarters to be the
best.
It removes the widest variety
of contaminants such as
salts, chemicals, bacteria
and other micro-organisms
from your water supply.

18. limitations of Distillinglimitations of Distilling
Produces flat tasting water that is stripped
of the trace minerals that your body needs.

19. Some doctors contend that this can lead to
multiple-mineral deficiencies within the body.
However some experts contend that most of the
bodies mineral needs are met through eating
food, not drinking water. Therefore the effect of
de-mineralized water on the body is still being
hotly debated

20. Chlorinating/ ChlorinationChlorinating/ Chlorination
Super-chlorination. This uses
a high dose of chlorine but
later neutralizes it using
hydrogen peroxide, and is
very effective.
Chlorine tablets. Used alone
these won't protect against
Guardia. Instead use a fine
filter and half a tablet.
