2. WaterPurification
India has many
resources to purify
water. The municipal
Committee of India
uses some techniques
to purify water are
Sedimentation
 Distillation
Flocculation
 Chlorination

3.  Firstly, the water is kept in a reservoir.

4. •Then, Water goes into a
sedimentation tank in which the solid
particles are allowed to settle down.

5. •After that, water passes through a
loading tank in which suspended
particles are allowed to settle down.

6. Then, water goes to a Filtration Tank.
When water passes
through fine sand
some solids or semi
solids which are left
stay between the
sand. Some dirt
which is left sticks
to gravel. After this
process the water is
cleaned.

7. When the water
passes through the
chlorination tank
Chlorine tablets are
mixed in it.
Chlorine is
sufficient to kill
bacteria in water.
