S.T.P Working Process
The first stage ensures incoming sewage is prepared for treatment. Pre-treatment removes coarse solids, grit, and floating debris, protecting downstream equipment.
Components & Functions:
Screens & Grit Chambers: Remove stones, plastics, and solids
Equalization Tanks: Balance flow and load for consistent treatment
Benefits:
Protects pumps and tanks from damage
Ensures smooth operation of the STP system
Reduces maintenance frequency
Primary treatment removes suspended solids and organic matter using sedimentation and chemical dosing.
Components & Functions:
Sedimentation Tanks: Settle suspended solids
Skimmers & Sludge Collectors: Remove floating matter
Chemical Dosing Units: Aid coagulation and flocculation
Benefits:
Reduces organic load for secondary treatment
Prevents clogging in biological units
Improves efficiency of downstream processes
Secondary treatment involves biological processes that degrade organic matter and reduce BOD/COD.
Components & Functions:
Aeration Tanks / Biofilters / MBBR: Microorganisms break down organic pollutants
Clarifiers: Separate treated water from biological sludge
Aerators & Diffusers: Provide oxygen for microbial activity
Benefits:
Reduces BOD, COD, and pathogens
Produces water safe for reuse or discharge
Ensures environmental compliance
Final stage removes residual impurities, color, and odor, ensuring treated water meets regulatory standards.
Components & Functions:
Sand & Activated Carbon Filters: Remove fine solids and color
UV / Chlorination Units: Disinfect water from bacteria and viruses
pH Adjustment Units: Stabilize water before discharge
Benefits:
Ensures compliance with CPCB and State Pollution Control Board norms
Produces safe, environmentally compliant water
Enables reuse in flushing, landscaping, or industrial applications
Notes
- STP solutions are used worldwide for domestic and industrial wastewater treatment.
- Treated water is suitable for safe discharge, reuse, and sustainability initiatives.
