Industrial wastewater management is an important part of responsible manufacturing, particularly for industries where water is used across multiple production and utility processes. An effective Effluent Treatment Plant (ETP) helps industries manage wastewater systematically, reduce pollutants, improve treated-water quality, and support compliance with applicable environmental requirements.
V Aqua successfully engineered, supplied, installed, and commissioned a 60 KLD MBR ETP Plant in Gurgaon, Haryana. The project was developed to provide a reliable and efficient solution for treating industrial wastewater generated from a manufacturing facility.
The treatment system uses Membrane Bioreactor (MBR) technology, which combines biological wastewater treatment with membrane filtration. This technology is particularly useful where a facility requires consistent treated-water quality along with a comparatively compact treatment footprint.
This case study explains the project requirement, wastewater treatment challenges, MBR technology, treatment process, major equipment, engineering approach, installation, commissioning, benefits, and operational considerations associated with the 60 KLD MBR Effluent Treatment Plant.

Project Background
The project was undertaken for an industrial manufacturing facility in Gurgaon, Haryana, where wastewater generated from routine operations required systematic collection and treatment.
Manufacturing facilities can produce wastewater with varying characteristics depending on production activities, cleaning operations, utility processes, and other water-consuming operations. Unlike domestic sewage, industrial effluent can contain a combination of suspended solids, biodegradable organic matter, chemicals, oils, colour, and other contaminants.
Therefore, an industrial ETP must be designed around the actual wastewater characteristics rather than using a generic treatment configuration.
The facility required a treatment system with a capacity of approximately 60 KLD, equivalent to 60,000 litres per day. The project requirement also emphasized reliable operation, consistent treatment performance, efficient use of available space, and the possibility of utilizing treated water for suitable applications.
V Aqua proposed an MBR-based ETP solution to address these requirements.
Project Requirement
The primary requirement was to establish a dedicated 60 KLD Effluent Treatment Plant capable of handling the facility’s daily industrial wastewater generation.
The major requirements included:
- Treatment capacity of 60 KLD
- Industrial wastewater treatment
- Effective biological treatment
- Reduction of organic pollutants
- Removal of suspended solids
- Consistent treated-water quality
- Compact plant configuration
- Membrane-based filtration
- Reliable day-to-day operation
- Appropriate sludge management
- Integrated pumping and aeration systems
- Electrical control and monitoring
- Complete installation and commissioning
The treatment system was designed to operate as an integrated process in which preliminary treatment, equalization, biological treatment, membrane filtration, treated-water collection, and sludge management work together.
Why MBR Technology Was Selected
One of the most important decisions in an industrial wastewater project is selecting the right treatment technology.
Conventional ETPs commonly use biological treatment followed by secondary clarification. In such systems, treated wastewater is separated from biological sludge through gravity settling.
An MBR ETP, on the other hand, combines biological treatment with membrane filtration. Instead of relying entirely on a conventional secondary clarifier for solid-liquid separation, the membrane system physically separates treated water from the biomass.
This provides several advantages where consistent treated-water quality and space efficiency are important.
What Is an MBR ETP Plant?
An MBR Effluent Treatment Plant is a wastewater treatment system that combines two major processes:
- Biological treatment
- Membrane filtration
During biological treatment, microorganisms consume and break down biodegradable organic matter present in wastewater.
Following biological treatment, membrane modules separate treated water from suspended solids and biomass. The membranes act as a physical filtration barrier, allowing treated water to pass through while retaining the majority of suspended solids and microorganisms within the biological system.
The result is a treatment process capable of producing relatively clear and low-suspended-solids permeate when properly designed and operated.
Advantages of MBR ETP Technology
For a 60 KLD MBR ETP Plant, the technology offers several practical advantages.
1. Consistent Treated Water Quality
Membrane filtration provides a strong physical separation barrier. This helps produce treated water with very low suspended solids and turbidity under appropriate operating conditions.
2. Compact Footprint
An MBR system can require less space than a conventional biological treatment system using large secondary clarifiers.
This makes MBR technology useful for industrial facilities where available installation space is limited.
3. Effective Biomass Retention
The membranes retain biomass within the biological reactor, allowing the system to operate with relatively high mixed-liquor concentrations.
4. Reduced Dependence on Sludge Settling
Conventional clarification depends heavily on the settling properties of biological sludge. MBR technology uses membranes for solid-liquid separation, reducing the dependence on gravity settling.
5. Suitable for Water Reuse
The relatively high quality of MBR permeate can make it suitable for further polishing and disinfection when treated water is intended for appropriate reuse applications.
6. Stable Biological Treatment
Maintaining biomass inside the reactor provides operators with greater control over biological treatment conditions.

Treatment Process of the 60 KLD MBR ETP Plant
The treatment process was developed as a sequence of interconnected stages. Each stage performs a specific function and prepares the wastewater for the next stage.
A simplified treatment flow can be represented as:
Industrial Effluent → Screening → Collection → Equalization → Biological Treatment → MBR Membrane Filtration → Treated Water Tank → Reuse / Discharge
The actual process configuration may be customized depending on wastewater analysis and project requirements.
1. Effluent Collection
Wastewater generated within the facility is first collected through the site’s effluent drainage and collection arrangement.
The collection system brings different wastewater streams together before they enter the treatment plant.
Proper collection is important because uncontrolled mixing, excessive hydraulic fluctuations, or direct discharge of untreated wastewater can negatively affect downstream treatment processes.
The collected effluent is then transferred toward the preliminary treatment section.
2. Preliminary Screening
The first treatment stage generally involves screening or other suitable preliminary treatment.
The purpose is to remove larger materials such as:
- Fibres
- Plastics
- Packaging materials
- Coarse suspended solids
- Other floating debris
Removing these materials at the beginning helps protect pumps, pipelines, aeration equipment, and membrane modules.
For an MBR system, preliminary treatment is especially important because membrane modules require effective upstream protection against larger particles and fibrous materials.
3. Equalization Tank
Industrial wastewater generation is rarely constant throughout the day.
Wastewater flow and pollutant concentration may change according to:
- Production schedules
- Cleaning operations
- Shift timings
- Raw-material processing
- Utility operations
- Daily water consumption
An equalization tank helps balance these variations.
Wastewater is collected and temporarily retained in the equalization tank before being transferred to the biological treatment section at a more controlled rate.
This helps reduce sudden hydraulic and organic loading fluctuations and supports stable biological treatment.
4. Biological Treatment
The equalized wastewater enters the biological treatment stage.
This is a critical part of the MBR ETP process.
Microorganisms present in the biological reactor consume biodegradable organic matter in the wastewater. Through controlled aeration and microbial activity, organic pollutants are converted into simpler and more stable forms.
Aeration provides oxygen required by aerobic microorganisms.
The biological treatment process helps reduce parameters such as:
- Biochemical Oxygen Demand (BOD)
- Biodegradable organic matter
- A portion of Chemical Oxygen Demand (COD)
- Suspended biological solids
The biological stage is carefully controlled because microbial activity plays a major role in overall ETP performance.
5. Membrane Bioreactor Stage
After biological treatment, the mixed liquor enters the MBR section.
This is the defining stage of the system.
The MBR contains membrane modules through which treated water is filtered.
The membrane barrier retains:
- Suspended solids
- Biological flocs
- Most microorganisms
- Fine particulate matter
Meanwhile, treated water passes through the membrane as permeate.
Because the membrane performs the solid-liquid separation, the system does not depend solely on conventional gravity settling for separation.
This is one of the primary reasons MBR technology can provide consistently clear treated water.
6. Membrane Aeration and Fouling Control
Membrane fouling is one of the important operational considerations in any MBR plant.
During operation, fine-bubble or coarse-bubble aeration is provided around the membrane surface depending on the membrane configuration.
The air movement helps reduce the accumulation of solids on the membrane surface.
The aeration system also supplies oxygen required for biological treatment.
Proper control of:
- Airflow
- Membrane flux
- Transmembrane pressure
- Cleaning frequency
- Sludge concentration
- Operating cycles
is important for maintaining membrane performance.
7. Treated Water Collection
The water passing through the membrane is collected as treated permeate.
The treated water can then be transferred into a treated-water storage tank.
Depending on the intended application, additional treatment such as:
- Disinfection
- Activated carbon polishing
- UV treatment
- Additional filtration
- RO treatment
may be incorporated where required.
The final treatment requirement should be determined according to the intended reuse or discharge application.
8. Sludge Management
Biological treatment naturally generates excess biomass.
Even though the MBR membrane retains biomass within the treatment system, a portion of excess sludge must periodically be removed to maintain suitable operating conditions.
The excess sludge can be directed toward an appropriate sludge-handling system.
Effective sludge management is an important part of maintaining stable ETP operation.
Expected Treated Effluent Quality
The quality of treated water produced by an MBR ETP depends on the influent characteristics, process design, operating conditions, membrane performance, and required treatment standards.
Typical parameters considered during industrial wastewater treatment include:
| Parameter | Typical Consideration |
|---|---|
| pH | Maintained within the required operating/discharge range |
| BOD | Significantly reduced through biological treatment |
| COD | Reduced according to wastewater biodegradability and process design |
| TSS | Very low after effective membrane filtration |
| Turbidity | Significantly reduced by membrane separation |
| Oil & Grease | Controlled according to influent characteristics and pretreatment |
| Colour | May require additional treatment depending on wastewater |
| Odour | Controlled through appropriate treatment and aeration |
It is important to note that final treated-water limits should be established according to the applicable consent conditions, discharge requirements, reuse application, and relevant regulatory standards rather than assuming identical values for every industrial project.
