Sewage Treatment Plant
A Sewage Treatment Plant (STP) is a facility that treats wastewater from households, industries, and commercial areas before discharging it into the environment or reusing it. The main objective is to remove contaminants like solids, organic matter, and harmful microorganisms to prevent pollution and protect public health.
Basic Treatment Process
- Primary Treatment – Removes large solids through screening and sedimentation.
- Secondary Treatment – Uses biological processes (microorganisms) to break down organic matter.
- Tertiary Treatment – Advanced filtration and disinfection for safe discharge or reuse.
Importance of STPs
- Prevents water pollution.
- Protects public health.
- Enables water reuse for irrigation and industries.
Common STP Types
- Conventional STPs – Activated sludge-based systems.
- Decentralized STPs – Compact units for small communities.
- Natural STPs – Constructed wetlands and lagoons.
Challenges & Future Trends
- High energy use and sludge disposal issues.
- Smart STPs using automation and AI.
- Zero Liquid Discharge (ZLD) for complete water recovery
