WATER TREATMENT PLANT (WTP)

DESIGN

1. Intake Structure

Collects raw water from river/lake and directs it to treatment plant.

2. Screening

Screens remove floating materials like leaves, plastic, debris.

3. Aeration

Aeration allows oxygen to mix with water to remove dissolved gases and reduce odor.

4. Coagulation

Chemical (Alum/Ferric Chloride) is added to water for particle destabilization.

5. Flocculation

Slow mixing allows small particles to combine into larger flocs.

6. Sedimentation

Water is kept in settling tanks where flocs settle at the bottom.

7. Filtration

Water passes through layers of sand & gravel to remove remaining fine particles.

8. Disinfection

Chlorine/UV/Ozone is applied to kill pathogens.

9. Storage & Distribution

Treated water stored in reservoirs and supplied to consumers.
