Coagulation: Dirty water has many particles floating around in it. Alum and other chemicals are added
to the water to form floe that is sticky and attracts the dirt into larger clumps. When they get heavy, they
sink to the bottom during sedimentation.
Sedimentation:
The heavy
particles settle to
the bottom and
the clear water at
the top moves on
to filtration.
Filtration: The water
goes through filters,
often made of sand,
gravel and charcoal
that will catch even
smaller particles that
float in the water.
Disinfection: A small amount of chlorine is added
to kill any bacteria or tiny organisms that may be in
the water.
Storage: Water
is stored in a
closed tank
(tower) or
reservoir so the
disinfection can
take place. It then
goes through
pipes and into
your home or
school.
