INTRODUCTION
-Water purification is the process of removing undesirable
chemicals, biological contaminants, suspended solids and
gases from contaminated water.
-The goal of this process is to produce water fit for a
specific purpose. Most water is disinfected for human
consumption (drinking water).
NEED FOR PURIFICATION
 The purification process of water may reduce the concentration of
particulate matter including suspended particles, parasites, bacteria, algae,
viruses, fungi; and a range of dissolved and particulate material derived
from the surfaces that water may have made contact with after falling
as rain.
 Various diseases spread through unpurified water:
• Diarrhoea
• Arsenicosis
• Cholera
• Fluorosis
• Guinea Worm Disease
• Typhoid
Types Of Purification
Drinking water is purified by the following methods:
 Filtration: The water passes through filters, some made
of layers of sand, gravel, and charcoal that help remove
even smaller particles.
 Boiling
 UV Treatment

Interpretation
After surveying 75 houses I found out that:
•
•
•
•
18 houses do not purify their drinking water
None of the houses prefer to purify drinking water by filtration
57 houses prefer to purify by boiling the water
None of the houses prefer to purify water by UV methods
Conclusion
I have come to the conclusion that boiling water is the best
method for purification of water. The reason is because it is
cheap and efficient.
the houses surveyed do not use filtration as it is a slow
process.
UV is also not used because it is a costly method and also
has its own cons like:
• The water being treated must be in no way turbid or cloudy.
• Ultraviolet purification offers no residual treatment.
