Conventional Sewage Treatment Plants (STPs) are engineered systems designed to treat domestic and commercial wastewater by removing suspended solids, organic matter, nutrients, and harmful microorganisms before the treated water is safely discharged or reused. These plants utilize a combination of physical, biological, and chemical treatment processes to produce treated water that meets applicable environmental standards.
Conventional STPs are widely used in residential communities, commercial buildings, institutions, hotels, hospitals, and industrial facilities, providing a reliable and sustainable solution for wastewater management.
How a Conventional Sewage Treatment Plant Works
Wastewater passes through multiple treatment stages to remove contaminants and improve water quality.
The treatment process typically includes:
- Screening removes large debris such as plastics, paper, and other solid waste.
- Grit Removal separates sand, gravel, and other heavy inorganic particles.
- Primary Sedimentation allows suspended solids to settle, reducing the organic load.
- Biological Treatment uses naturally occurring microorganisms to break down dissolved organic matter through processes such as the Activated Sludge Process (ASP).
- Secondary Clarification separates treated water from biological sludge.
- Disinfection using chlorine, UV, or other approved methods reduces harmful microorganisms before discharge or reuse.
- Sludge Handling thickens and dewaters sludge for safe disposal or further treatment.
