Water Treatment on how to make the water clean

Water Treatment

1. WATER TREATMENT
Presented by Shane Jagurap

2. WATER TREATMENT
Manipulation of water from various
sources to achieve a water quality that
meets specified goals or standards set
by the community through its regulatory
agencies.

3. WATER TREATMENT PROCESS
Rapid mixing
Coagulation
Flocculation
Sedimentation
Filtration
Disinfection

4. RAPID MIXING
A process that quickly and thoroughly distributes
coagulants (chemical agents) throughout the
water to ensure even interaction with suspended
particles.

5. COAGULATION
This involves adding chemicals with a positive
charge to the water which should neutralize the
negative charge of dirt and other dissolved
substances. Such chemicals include iron and
specific types of salt.

6. FLOCCULATION
The addition of chemicals (coagulants) to
destabilize and neutralize the charges on
suspended particles, causing them to clump
together into larger aggregates called flocs.

8. SEDIMENTATION
Sedimentation is the process where heavier particles
(flocs) sink to the bottom while clearer water stays on top.

10. FILTRATION
Filtration is the process where water is passed through a
medium (such as sand or activated carbon) to remove
remaining particles and impurities.

12. DISINFECTION
Disinfection is the final process where harmful
microorganisms (bacteria, viruses, parasites) are
destroyed or inactivated.

14. OTHER TREATMENT PROCESS
FOR DRINKING WATER
The drinking water treatment process involves
a series of steps that ensure the water is
clean, safe, and free from harmful
contaminants before it reaches consumers.
These steps help remove physical, chemical,
and biological impurities to meet health and
safety standards for drinking water.

15. OTHER TREATMENT PROCESS FOR
DRINKING WATER
• Fluidization
• Chemical processes
• Screening devices
• Aeration
• Ozonation
• Boiling

16. • Fluidization -
A process where water flows fast enough to lift small
particles, helping to mix chemicals or clean filters in water
treatment.
• Chemical Process -
Using chemicals to remove impurities, kill bacteria,
or improve water quality (e.g., chlorine for
disinfection).
• Screening Devices -
Barriers or filters that remove large objects like
leaves, sticks, or trash before the main treatment
begins.

17. • Aeration -
Mixing water with air to remove unwanted gases (like
carbon dioxide) and improve taste and smell.
• Ozonation -
• Boiling -
is a simple, but effective method of disinfecting
water by applying heat to kill harmful
microorganisms.
Using ozone gas to kill bacteria, viruses, and other
harmful organisms in water.
