A Sewage Treatment Plant is an engineered facility
that treats sewage by separating physical solids and reducing biodegradable pollutants,
suspended matter, nutrients, and microorganisms.
Sewage can contain materials such as organic waste, suspended particles, detergents, oils,
nutrients, bacteria, and other contaminants. If untreated wastewater is released directly
into the environment, it can adversely affect surface water, groundwater, soil, and public
hygiene.
An STP therefore provides controlled treatment before the wastewater is discharged or
considered for reuse. The final treatment configuration depends on the quality of incoming
sewage and the required quality of the treated water.
How Does a Sewage Treatment Plant Work?
A Sewage Treatment Plant (STP) works through a systematic sequence of treatment stages. Each
stage is designed to remove a specific type of contaminant and prepare the wastewater for
the next treatment step. The overall working process can be explained as follows:
1. Sewage Collection and Inlet: Wastewater generated from toilets,
bathrooms, kitchens, commercial areas, and other sources is collected through a
sewer network and directed to the STP inlet. The incoming sewage is first inspected
for flow and basic characteristics before entering the treatment process.
2. Screening: The wastewater passes through coarse and fine screens
that remove larger materials such as plastics, cloth, paper, sanitary waste, and
other floating debris. This protects pumps, pipelines, blowers, and downstream
treatment equipment from blockage or mechanical damage.
3. Grit and Solid Removal: After screening, heavier inorganic
particles such as sand, grit, gravel, and small stones are separated. Removing these
materials prevents abrasion and accumulation inside tanks and mechanical equipment.
4. Equalization and Flow Balancing: An equalization tank may be
provided to balance variations in wastewater flow and pollutant concentration. It
helps maintain a more consistent flow to the biological treatment section,
particularly where sewage generation varies significantly throughout the day.
5. Biological Treatment: Depending on the selected STP technology,
biological treatment may use MBBR, SBR, MBR, or Activated Sludge Process (ASP).
Aeration equipment supplies oxygen when required to support aerobic microorganisms.
6. Solid-Liquid Separation: Following biological treatment,
microorganisms and suspended solids must be separated from the treated water.
Conventional systems generally use a clarifier for settling, while membrane-based
systems use filtration membranes.
7. Tertiary Treatment: Additional treatment is provided when the
required treated-water quality is higher than that achieved through secondary
treatment alone. Depending on the application, this stage may include pressure sand
filtration, activated carbon filtration, ultrafiltration, membrane treatment, or
nutrient removal.
8. Disinfection: The filtered water undergoes disinfection to
reduce microorganisms. Ultraviolet (UV) treatment or chlorination may be used
depending on the plant design and intended reuse or discharge requirements.
9. Treated Water Collection and Reuse: After completing the
required treatment stages, the treated water is collected in a treated-water tank.
Subject to applicable quality requirements, it may be used for non-potable purposes
such as toilet flushing, gardening, landscaping, or other approved applications, or
discharged through the designated outlet.
10. Sludge Handling: Solids separated during the treatment process
are collected for sludge management. Depending on the plant configuration, sludge
may undergo thickening, stabilization, drying, or mechanical dewatering before
appropriate disposal or further processing.
Types of Sewage Treatment Plants
Sewage Treatment Plants (STPs) are designed in different configurations according to sewage
characteristics, treatment capacity, available space, treated-water quality requirements,
installation conditions, and the intended reuse of treated water. Different biological and
physical treatment technologies are selected depending on factors such as BOD, COD, TSS,
nitrogen, phosphorus, hydraulic loading, peak flow, and discharge or reuse standards. The
major types of sewage treatment plants include MBBR, SBR, MBR, ASP, extended aeration, FAB,
packaged, prefab, modular, containerized, decentralized, and tertiary treatment systems.
1. MBBR Sewage Treatment Plant
A Moving Bed Biofilm Reactor (MBBR) Sewage Treatment Plant
uses specially designed plastic biofilm carriers inside an aeration tank to
provide a large protected surface area for microorganisms. The
microorganisms grow as a biofilm on the carriers and biologically degrade
organic pollutants present in sewage. Continuous aeration keeps the carriers
moving and maintains contact between sewage, microorganisms, and oxygen.
MBBR STPs are commonly used for residential complexes, commercial buildings,
hotels, hospitals, institutions, and industrial facilities where reliable
biological treatment and compact plant construction are required. They are
particularly suitable when the plant needs higher treatment efficiency
without substantially increasing the tank volume. Compared with conventional
activated sludge systems, MBBR can provide greater biomass retention and is
relatively flexible under variations in organic loading.
Technical considerations: Reactor sizing
depends on organic loading, carrier filling ratio, required oxygen transfer,
hydraulic retention time, influent BOD/COD, and required treated-water
quality. Typical systems incorporate screening, equalization, primary
treatment, MBBR aeration, secondary clarification, sludge handling, and
optional tertiary treatment.
A Sequencing Batch Reactor (SBR) Sewage Treatment Plant
performs biological treatment in a controlled sequence within the same
reactor. Typical operating cycles include fill, react, settle,
decant, and idle stages. Aeration and mixing are controlled
according to the treatment cycle, allowing biological oxidation and solids
separation to take place in a batch-based process.
SBR systems are used where consistent treatment performance, automation, and
efficient use of plant area are important. They are particularly suitable
for residential developments, institutions, hotels, commercial complexes,
and projects where the sewage flow varies throughout the day. Unlike
continuous-flow MBBR systems, SBR uses timed treatment cycles and does not
necessarily require a separate secondary clarifier.
Technical considerations: Cycle duration,
reactor volume, aeration time, settling period, decant volume, sludge
wasting rate, dissolved oxygen, and influent loading must be carefully
controlled. PLC-based automation is commonly used for blower operation,
mixers, decanters, valves, and treatment-cycle sequencing.
A Membrane Bioreactor (MBR) Sewage Treatment Plant combines
biological treatment with membrane filtration. Microorganisms degrade
organic matter in the bioreactor, while membranes provide fine solid-liquid
separation. Depending on the system configuration, submerged or external
membrane modules can be used to produce highly clarified treated water with
very low suspended solids.
MBR technology is selected when high-quality treated water is required,
particularly for applications involving water reuse, toilet flushing,
landscaping, cooling, process applications, or other non-potable purposes.
It can achieve a smaller footprint than conventional biological treatment
followed by separate clarification and advanced filtration because membrane
separation replaces conventional secondary settling.
Technical considerations: Membrane flux,
transmembrane pressure, mixed liquor suspended solids, membrane fouling, air
scouring, sludge retention time, cleaning frequency, and membrane
replacement requirements are important design parameters. MBR systems
generally require closer operational control than simpler biological STPs.
4. Activated Sludge Process (ASP) Sewage Treatment Plant
An Activated Sludge Process (ASP) Sewage Treatment Plant
uses suspended microorganisms in an aeration tank to biologically oxidize
organic pollutants. Air or oxygen is supplied to maintain the microorganisms
under aerobic conditions, after which the mixed liquor flows to a secondary
clarifier where biological solids settle. A portion of the settled sludge is
returned to the aeration tank as return activated sludge (RAS), while excess
sludge is removed for further handling.
ASP is used for municipal, residential, institutional, and commercial sewage
treatment where a conventional continuous-flow biological treatment process
is appropriate. It is a well-established technology and can be adapted to
different treatment capacities and effluent requirements.
Technical considerations: Important
parameters include mixed liquor suspended solids (MLSS), dissolved oxygen,
sludge retention time (SRT), food-to-microorganism ratio (F/M), return
sludge rate, hydraulic retention time, sludge volume index (SVI), and
secondary clarifier loading. Compared with attached-growth systems such as
MBBR, ASP depends more heavily on maintaining the required suspended biomass
concentration and sludge settling characteristics.
An Extended Aeration Sewage Treatment Plant is a modified
activated sludge process operated with a relatively long aeration period and
a low food-to-microorganism ratio. The longer biological retention allows
microorganisms to stabilize more organic matter and promotes endogenous
respiration, resulting in comparatively lower excess sludge production than
conventional high-rate activated sludge systems.
Extended aeration is commonly selected for residential societies, schools,
hospitals, hotels, institutions, and other facilities where sewage flow is
relatively predictable and simple biological operation is preferred. It is
useful where sludge handling requirements need to be minimized and
sufficient space is available for longer biological retention.
Technical considerations: Aeration tank
volume, oxygen demand, MLSS, SRT, F/M ratio, dissolved oxygen, settling
characteristics, and sludge wasting are important design factors. The longer
aeration requirement can increase blower energy consumption compared with
some compact treatment configurations.
A Fluidized Aerobic Bed (FAB) Sewage Treatment Plant uses
small media particles or carriers on which microorganisms grow as biofilm.
Aeration keeps the media in suspension and provides oxygen for biological
treatment. The attached biomass increases the effective biological surface
area within the reactor and supports the degradation of organic pollutants.
FAB systems are used where compact biological treatment and relatively high
biomass concentration are required. They can be considered for residential,
commercial, institutional, and industrial sewage applications where
available installation space is limited.
Technical considerations: Media
characteristics, media loading, aeration rate, oxygen transfer, hydraulic
retention time, organic loading, and solids separation are important design
parameters. The media and reactor configuration differentiate FAB systems
from conventional suspended-growth activated sludge plants.
A Packaged Sewage Treatment Plant is a factory-assembled or
factory-fabricated treatment system supplied as a compact package with major
treatment components integrated into a defined plant configuration.
Depending on the application, packaged systems may use MBBR, SBR, FAB,
extended aeration, or other biological processes.
Packaged STPs are commonly used for apartments, hotels, resorts, schools,
hospitals, offices, commercial buildings, and smaller industrial facilities
where rapid installation and a compact footprint are required. They are
useful when the project requires a standardized treatment package rather
than extensive civil construction at the site.
Technical considerations: Selection depends
on sewage flow, peak hydraulic loading, BOD/COD concentration, TSS,
treatment objectives, available installation area, tank material, automation
requirements, and treated-water reuse. The term packaged describes the
supply format and compact integration; it does not itself define a
particular biological treatment process.
A Prefab Sewage Treatment
Plant is manufactured or fabricated off-site in sections, tanks,
modules, or assemblies and then transported to the project location for
installation and commissioning. Prefabrication allows a substantial portion
of fabrication and quality control to be completed in a controlled
manufacturing environment before the equipment reaches the site.
Prefab STPs are used when faster site installation, reduced civil
construction, controlled fabrication, or limited construction space is
important. They are suitable for residential, commercial, institutional,
hospitality, and industrial projects where the treatment system needs to be
installed with comparatively less site fabrication.
Technical considerations: Structural
design, tank material, module dimensions, transportation limitations,
lifting requirements, interconnection piping, equipment accessibility,
corrosion protection, and site foundation requirements must be considered.
Prefabrication is primarily an installation and construction approach, so
the underlying treatment process may be MBBR, SBR, FAB, or another suitable
technology.
A Modular Sewage Treatment Plant consists of treatment units
designed as separate modules that can be assembled into a complete system.
Modules may include screening, equalization, biological treatment,
clarification, filtration, disinfection, sludge handling, and tertiary
treatment stages.
Modular STPs are useful for projects where treatment capacity may need to
increase over time or where the plant must adapt to changing site
requirements. They can be suitable for campuses, residential developments,
commercial facilities, industrial sites, and infrastructure projects with
phased expansion.
Technical considerations: Hydraulic flow
distribution, module capacity, interconnecting pipework, pumping
requirements, control logic, available space, future expansion provisions,
and equalization capacity should be considered during design. Additional
modules can be incorporated when the overall hydraulic and organic loading
requirements increase, subject to the original plant design.
A Containerized Sewage
Treatment Plant integrates treatment equipment into a transportable
container or container-like enclosure. The system can be supplied with major
treatment equipment, electrical panels, piping, pumps, blowers, and control
systems pre-installed or assembled to reduce site installation work.
Containerized STPs are used for temporary facilities, remote locations,
construction camps, infrastructure projects, industrial sites, emergency
installations, and locations where conventional permanent construction is
difficult. Their transportability makes them useful when the treatment
system may need to be relocated or installed with limited site
infrastructure.
Technical considerations: Container
dimensions, equipment layout, ventilation, heat management, corrosion
protection, electrical requirements, access for maintenance, lifting and
transportation arrangements, and climatic conditions must be evaluated. The
containerized format can accommodate different treatment processes depending
on the required capacity and effluent quality.
A Decentralized Wastewater Treatment System (DEWATS) treats
sewage close to the point where it is generated rather than transferring all
wastewater to a large centralized treatment facility. Depending on the
project, decentralized systems can combine processes such as settling,
anaerobic treatment, aerobic biological treatment, filtration, constructed
wetlands, and disinfection.
DEWATS is used for remote communities, institutions, residential clusters,
rural developments, campuses, resorts, and other locations where centralized
sewer infrastructure is unavailable or impractical. It reduces the need for
long-distance sewage conveyance and can be designed according to the
wastewater generation pattern of a specific local area.
Technical considerations: Local sewage
flow, influent characteristics, hydraulic retention time, anaerobic and
aerobic treatment stages, land availability, sludge management, odor
control, groundwater protection, and treated-water disposal or reuse must be
considered. The treatment configuration can vary significantly according to
local site conditions and project requirements.
A Tertiary Sewage Treatment Plant provides advanced
treatment after primary and secondary biological treatment to further
improve treated-water quality. Depending on the reuse or discharge
requirement, tertiary treatment can include pressure sand filtration,
activated carbon filtration, ultrafiltration, membrane treatment, nutrient
removal, advanced oxidation, and disinfection using chlorine, UV, or ozone.
Tertiary treatment is used when the treated sewage needs to meet more
stringent quality requirements or when the water is intended for reuse.
Common reuse applications include landscaping, toilet flushing,
cooling-water makeup, gardening, and selected industrial processes, subject
to the required water-quality criteria.
Technical considerations: The selection of
tertiary treatment depends on residual TSS, turbidity, BOD, COD, nutrients,
microbial quality, dissolved solids, and the final reuse requirement. For
example, filtration and disinfection may be sufficient for some reuse
applications, while membrane-based treatment may be required where
substantially lower suspended solids or dissolved contaminant levels are
needed.

How to Choose the Right STP Plant for Your Project?
Selecting the right Sewage Treatment Plant depends on the wastewater characteristics,
required treatment capacity, available space, treated-water quality, and operating
requirements of the project. Consider the following factors before finalizing an STP
technology:
Wastewater Flow and Capacity: Determine average and peak sewage
flow, occupancy, water consumption, and future expansion requirements to establish
the appropriate KLD capacity.
Wastewater Quality: Evaluate parameters such as BOD, COD, TSS, pH,
nitrogen, phosphorus, oil, and grease to select a suitable treatment process.
Available Space: Consider the footprint required for tanks,
equipment, piping, electrical panels, access, and maintenance areas. Compact options
such as MBBR, MBR, and packaged systems may suit space-constrained sites.
Treated-Water Requirement: Identify whether the treated water will
be discharged or reused for applications such as toilet flushing, gardening,
landscaping, or other approved non-potable purposes.
Automation and Operation: Consider PLC-based controls, sensors,
alarms, and monitoring requirements based on operator availability and project
needs.
Sludge and Maintenance: Evaluate sludge generation, dewatering,
disposal, equipment maintenance, energy consumption, and other long-term operating
requirements.
Lifecycle Cost: Compare the complete lifecycle requirements,
including installation, electricity, chemicals, consumables, maintenance, manpower,
and equipment replacement—not only the initial purchase price.
A proper STP selection should therefore be based on the project's actual wastewater
characteristics and treatment objectives rather than selecting a technology based only on
capacity or price.
Applications of Sewage Treatment Plant
As Sewage Treatment Plant Manufacturers in Pune, our all types are used in various types of
industrial sectors such as:
Residential Communities: Apartment complexes, housing societies,
townships, and residential developments generate wastewater from bathrooms,
kitchens, laundry, and other domestic activities.
Hotels and Resorts: Guest rooms, restaurants, kitchens, laundry
facilities, and recreational areas can generate significant wastewater requiring
centralized treatment.
Hospitals: Healthcare facilities require carefully planned
wastewater treatment systems based on their wastewater sources and applicable
requirements.
Educational Institutions: Schools, colleges, universities, hostels,
and campuses can use decentralized or centralized treatment facilities.
Municipalities: Municipal wastewater projects can use large-scale
treatment infrastructure to serve communities and urban areas.
Industrial Facilities: Industrial premises may require an STP for
domestic sewage generated by employees and supporting facilities. Industrial process
wastewater may require a separate Effluent
Treatment Plant (ETP) or another specialized treatment system.
Indian Railways: Railway stations, residential colonies, workshops,
and associated facilities can use specialized wastewater treatment solutions
according to site requirements.
Sugar Industry: Sugar manufacturing facilities may require sewage
treatment for domestic wastewater generated within their premises, while process
effluent generally requires separate evaluation.
Ships and Off-Grid Locations: Marine facilities and remote
locations may require compact systems where connection to centralized sewer
infrastructure is not practical.
Sewage Treatment Plant Capacity
STP capacity is normally expressed in KLD (Kilolitres per Day). 1 KLD = 1,000 litres/day =
1 cubic metre/day
The required capacity should be calculated from actual sewage generation rather than selected
solely on the basis of building size or available space.
Common Capacity Examples

29,167 L/hour
1,000 KLD
1,000,000 L/day
41,667 L/hour
For example, a 100 KLD system represents a nominal daily treatment volume of 100,000 litres
under its design conditions.
Capacity calculation should consider average flow, peak flow, occupancy, water consumption,
sewage-generation rate, seasonal variations, and possible future expansion.
Sewage Treatment Plant Installation & Maintenance
Installation begins with site assessment and preparation. Equipment is then positioned and
interconnected through process piping, electrical connections, control systems, and
supporting infrastructure.
The commissioning stage includes equipment
testing, trial operation, process adjustment, and operator training.
Regular maintenance is necessary to maintain stable performance. Typical activities include:
Checking pumps and blowers
Cleaning screens
Inspecting diffusers
Monitoring aeration
Backwashing filters
Checking membrane performance, where applicable
Removing accumulated sludge
Inspecting electrical panels
Monitoring treated-water quality
A preventive maintenance program can reduce
unplanned downtime and help identify equipment problems before they affect the treatment
process.

Project Challenge
The residential township required a centralized STP capable of handling fluctuations
in sewage generation caused by varying occupancy patterns. The client also wanted to
maximize treated-water reuse rather than discharge treated wastewater unnecessarily.
The major requirements were:
500 KLD treatment capacity
Reliable biological treatment
Handling of variable hydraulic loading
Consistent treated-water quality
Treated-water reuse
Compact and practical plant arrangement
Easy operation and maintenance
Automated process control
Shree Water Tech's Solution
Shree Water Tech selected an SBR-based treatment configuration because the process
can integrate biological treatment and settling within controlled batch cycles. The
treatment system was configured around the hydraulic and organic loading of the
residential sewage stream.
The biological stage provides removal of biodegradable organic matter, while tertiary
filtration and disinfection improve the final treated-water quality for reuse
applications.
Project Outcome
The completed system provides centralized treatment of residential sewage with
provision for treated-water recycling. Approximately 350 KLD of treated wastewater
can be directed toward suitable non-potable applications such as flushing, gardening
and landscaping, subject to actual plant operation and water-quality results.

Project Challenge
The commercial facility experienced variations in sewage generation based on employee
occupancy, working schedules and daily operating patterns. At the same time, the
available installation area was restricted. The STP therefore needed to provide:
High treatment efficiency
Compact footprint
Stable biological treatment
Low operational complexity
Easy maintenance
Treated-water reuse
Reliable operation under variable loading
Shree Water Tech's Solution
Shree Water Tech developed an MBBR-based biological treatment system using attached
microbial growth on carrier media. The MBBR process provides a relatively compact
biological treatment stage while allowing the plant to accommodate variations in
organic loading.
The completed STP provides the commercial facility with a centralized
wastewater-treatment system designed for approximately 250 KLD capacity. Treated
wastewater can be recovered for suitable non-potable applications including flushing
and landscaping.

Project Challenge
Industrial campuses can experience significant variations in domestic sewage
generation due to:
Employee attendance
Multiple work shifts
Production schedules
Holidays
Canteen usage
Weekend occupancy
A further engineering consideration was the need to prevent industrial process
wastewater from entering the domestic STP, since process effluent may contain
contaminants unsuitable for conventional sewage biological treatment.
Shree Water Tech's Solution
Shree Water Tech developed a high-capacity MBBR system with adequate equalization and
biological-treatment capacity.
The equalization stage helps moderate fluctuations in hydraulic and organic loading
before biological treatment.
Project Outcome
The system provides a dedicated treatment solution for domestic wastewater generated
within the industrial campus. The treated-water system can support non-potable
reuse, helping reduce dependence on freshwater for applications such as landscaping
and flushing.

FAQ’s
An STP is primarily designed for sewage and domestic wastewater, while an ETP
(Effluent Treatment Plant) is generally designed to treat industrial process
effluent. Industrial wastewater characteristics determine which treatment system is
appropriate.
BOD, or Biochemical Oxygen Demand, indicates the amount of dissolved oxygen
microorganisms require to biologically break down biodegradable organic matter in
wastewater. It is an important parameter for evaluating biological treatment
requirements.
COD, or Chemical Oxygen Demand, represents the oxygen equivalent required to
chemically oxidize organic and certain inorganic substances in wastewater. COD is
commonly used alongside BOD to characterize wastewater.
Sludge can be collected and subjected to processes such as thickening, stabilization,
drying, or mechanical dewatering. Its final handling depends on its characteristics
and applicable disposal or reuse requirements.
Yes. STPs can incorporate automatic controls using electrical panels, sensors,
timers, alarms, and PLC-based systems. The degree of automation depends on the
project and operating requirements.
Performance can be evaluated by monitoring parameters such as flow, pH, dissolved
oxygen, suspended solids, BOD, COD, and other project-specific water-quality
indicators.
