A A Sewage Treatment Plant (STP) is a wastewater treatment system that collects and treats domestic and commercial sewage before safe discharge or reuse. It uses physical, biological, and chemical processes to remove solids, organic matter, harmful microorganisms, nutrients, oil, and grease, while reducing pollutants such as BOD, COD, and TSS.
Treated water can be safely discharged or reused for non-potable purposes such as toilet flushing, landscaping, gardening, and cooling, in accordance with applicable standards. STPs support sustainable water management by reducing pollution, conserving freshwater, and enabling wastewater reuse.
As experienced Sewage Treatment Plant Manufacturers in Pune, we design and manufacture efficient wastewater treatment systems that process sewage through multiple stages. Each stage is designed to remove solids, organic pollutants, suspended particles, and harmful microorganisms to produce treated water suitable for reuse, recycling, or safe discharge, depending on the application and applicable standards.
| Step | Sewage Treatment Process | Description |
|---|---|---|
| 01 | Preliminary Treatment – Screening & Grit Removal | Incoming sewage passes through screens to remove large solids, plastics, rags, and other debris. Grit removal then separates sand, gravel, and other heavy particles, helping protect treatment equipment and maintain smooth plant operation. |
| 02 | Primary Treatment – Sedimentation | During primary settling, heavier suspended solids settle at the bottom of the tank, while oil, grease, and floating impurities are removed from the surface. This reduces the solid and organic load before biological treatment. |
| 03 | Secondary Treatment – Biological Treatment | Beneficial microorganisms break down dissolved and biodegradable organic matter present in the wastewater. This biological treatment significantly reduces pollutants and improves the quality of the treated water. |
| 04 | Tertiary Treatment – Filtration & Disinfection | Advanced treatment methods such as fine filtration and disinfection remove remaining suspended particles and harmful microorganisms. Depending on the treatment quality achieved, the water can be considered for suitable non-potable reuse or compliant discharge. |
| 05 | Sludge Treatment & Management | Sludge generated during the treatment process is collected and managed through processes such as thickening, dewatering, and, where applicable, anaerobic digestion. Proper sludge management supports safe disposal and potential beneficial reuse. |
A well-designed Sewage Treatment Plant (STP) combines physical, biological, and advanced treatment processes to achieve consistent wastewater treatment performance. Depending on the project requirements, factors such as sewage characteristics, treatment capacity, available space, water-reuse objectives, and applicable discharge standards are considered when selecting the appropriate treatment technology.
As Sewage Treatment Plant Suppliers in Pune, we offer a wide range of advanced sewage treatment technologies tailored to different capacities, spaces, and operational requirements.

Challenge: The main challenge was to provide reliable sewage treatment within a restricted installation area. The commercial facility also experienced fluctuations in wastewater generation due to variations in occupancy and operating schedules.
Client Requirements:
Envocare's Solution: Envocare developed a compact 250 KLD MBBR sewage treatment system based on the site's hydraulic loading and treatment requirements.
Treatment Process:
Screening → Grit Removal → Equalization → MBBR Biological Treatment →
Secondary Clarification → Pressure Sand Filtration →
Activated Carbon Filtration → Disinfection
The MBBR process provided a robust biological treatment stage using attached microbial growth on specially designed bio-media.
Treatment Parameters:
| Parameter | Influent | Target Treated Water |
|---|---|---|
| BOD (mg/L) | Approximately 220 | <20 |
| COD (mg/L) | Approximately 400 | <50 |

| Reuse Quantity | Approximately 600 KLD |
| O&M | 12 Months |
Challenge: The facility experienced considerable variation in sewage generation depending on employee occupancy, working shifts, weekends, and holidays.
Another important engineering consideration was the separation of domestic sewage from industrial process wastewater. Since process effluent can have significantly different characteristics, the sewage treatment system was designed specifically for the domestic wastewater stream.
Envocare's Solution: Envocare developed a 1,000 KLD MBBR STP with adequate equalization and biological treatment capacity to accommodate variations in wastewater flow.
Treatment Process:
Coarse Screening → Fine Screening → Grit Removal → Equalization →
MBBR → Secondary Clarification → Tertiary Filtration →
Disinfection → Treated Water Storage
The system was designed around the expected hydraulic and organic loading of the domestic sewage stream.

A Sewage Treatment Plant (STP) treats domestic and commercial sewage by removing solids, organic matter, and harmful microorganisms. The treated water can be safely discharged or reused for suitable non-potable applications.
The cost of an STP depends on treatment capacity, technology, wastewater characteristics, and site conditions. The final cost is determined based on project requirements and the level of treatment required.
STP treated water is generally intended for non-potable applications rather than drinking. It can be reused for toilet flushing, gardening, landscaping, road cleaning, and cooling, depending on treatment quality and applicable requirements.
Chemical requirements vary depending on the STP design and treatment process. Chlorination and other disinfection methods may be used during tertiary treatment to control harmful microorganisms.
The main stages include preliminary treatment, primary sedimentation, secondary biological treatment, tertiary filtration and disinfection, and sludge treatment. Each stage removes specific pollutants from sewage.
Common STP technologies include MBBR, SBR, MBR, Activated Sludge Process (ASP), Extended Aeration, and Conventional STP. The suitable technology depends on capacity, wastewater characteristics, and available space.
MBBR (Moving Bed Biofilm Reactor) uses floating bio-media that support beneficial microorganisms for biological treatment. It is a compact and efficient solution for residential, commercial, and industrial applications.
SBR (Sequential Batch Reactor) treats sewage through filling, aeration, settling, and discharge cycles in a single tank. It is suitable for projects with fluctuating sewage flow.
MBR (Membrane Bioreactor) combines biological treatment with membrane filtration to produce high-quality treated water. It is suitable for advanced water reuse applications and projects with limited space.
BOD and COD indicate the level of organic pollutants in wastewater, while TSS represents suspended solid particles. STPs are designed to reduce these pollutants and improve treated water quality.
Treated STP water can be reused for toilet flushing, gardening, landscaping, road cleaning, and cooling systems. Reuse helps conserve freshwater and supports sustainable water management.
STPs are commonly used in residential societies, commercial buildings, hotels, hospitals, schools, industries, airports, railway stations, and municipal areas. They help manage sewage safely and efficiently.
An STP improves wastewater quality, reduces water pollution, and supports water recycling. It also helps conserve freshwater, reduce operating costs, and meet environmental requirements.
Sludge collected during treatment is processed and dewatered for safe disposal or beneficial reuse. Depending on the system, sludge may also undergo further treatment such as anaerobic digestion.
