Successfully Installed 90 KLD STP Plant at Great Lakes Institute of Management Gurgaon
Good wastewater management is an important need for schools, residential campuses, commercial buildings, hotels, hospitals and other facilities producing large amounts of domestic sewage each day. A well-designed Sewage Treatment Plant is not just a tool for helping an institution responsibly manage its wastewater output, but it can also enable treated wastewater to be recycled for beneficial purposes other than potable water, thereby minimizing the need for fresh water.
Our team successfully installed a Sewage Treatment Plant of 90 KLD at Great Lakes Institute of Management, Gurgaon. The project was conceptualized to meet the following criteria: wastewater treatment system that is efficient, reliable and user friendly; and treats wastewater generated during the various activities within the institutional campus.
Great Lakes Institute of Management says it has a campus in the Delhi NCR corporate hub with a spread of around 7.5 acres, making the need for reliable infrastructure to run the campus essential.
The project for KLD STP has been conducted with a focus on effective treatment of the sewage, stable plant operation, recovery of treated water, ease of maintenance and sustainability.
Project Overview
Design, supply, installation, testing and commissioning of a 90 KLD Sewage Treatment Plant for Great Lakes Institute of Management, Gurgaon.
Wastewater generated in educational campuses comes from various sources such as washrooms, toilet, kitchen, housekeeping activities, hostel, administrative area and other utility areas. This wastewater, if released untreated, can cause water pollution, bad smell, sanitation issues and unnecessary strain on freshwater.
Hence, the purpose of this project was to set up an integrated treatment plant, which can receive the sewage generated inside the campus and treat it using a combination of physical, biological and filtration methods.
The plant was designed to:
- Capable of treating up to 90 KLD of sewage per day.
- Minimize the presence of organic and suspended pollutants in wastewater.
- Generate treated water, suitable for approved non-potable reuse applications.
- Minimise odour and operational problems.
- Offering a compact and efficient treatment solution.
- Minimise use of freshwater by using treated water.
- Facilitate convenient operation and routine maintenance.
- Promote environmentally friendly waste management practices on campus.
The successful installation reflects our expertise as a Sewage Treatment Plant Manufacturer in Gurgaon to create customized STPs based on the institutions’ wastewater generation pattern, the available space, the requirement of wastewater treatment, and operating requirements.
Client Details
| Field | Details |
| Sponsor | Great Lakes Institute of Management |
| Project Category | I.S.T.P. |
| Application | Treatment & Reuse of domestic wastewater that is produced in the campus. |
| Industry Segment | Education / Institutional Infrastructure |
Great Lakes Institute of Management has its campus in Gurgaon, Delhi NCR. It is a contemporary Management Education institution located in the business heart of NCR, Delhi.
A wastewater system needs to accommodate fluctuations in sanitary drains between morning and evening for an institutional campus. Hydraulic loads may be different in student activity areas, residential facilities, food service areas, washrooms, administrative areas, and housekeeping activities.
Therefore, the STP was planned to be an integrated wastewater treatment system that could cater to the day-to-day needs of the campus and still provide reliable treatment.
Project Location
The Great Lakes Gurgaon campus is situated in Delhi NCR area. The public data obtained from the institute highlights that the Gurgaon campus is located in a strategic business and educational hub in the NCR.
Gurgaon, also now Gurugram, has seen significant growth in institutional, residential, commercial, hospitality, healthcare and corporate infrastructure. This further stresses the need for decentralised wastewater treatment and good water reuse.
When it comes to choosing the Sewage Treatment Plant Manufacturer in Gurgaon, a good Sewage Treatment Plant should not only be chosen based on the capacity. The wastewater characteristics, available space, hydraulic differences, ease of operation, sludge management, energy needs, and treated water use should also be taken into account when designing it.
These were taken into account when planning and installing the 90 KLD.
Plant Capacity
The installed Sewage Treatment Plant has a treatment capacity of:
90 KLD is the term used for 90 Kilolitres per day.
Under the design conditions mentioned the sewage treatment plant can handle up to about 90,000 litres of sewage every day.
One of the most crucial steps in designing an STP is determining capacity. An undersized plant may hydraulically overload the plant and cause sub-optimal treatment, while a significantly oversized plant will cost more than is needed without providing any treatment benefit.
Some institutional projects may also have significant variations in sewage flows during the day. Peaks may be in the mornings, lunch times, break time, evenings or hostel time.
Thus collection and equalisation is essential to ensure balance of the sewage before the biological treatment.
The selection of the 90 KLD capacity was determined to be adequate for the site’s needs, but also to insure that the treatment stages run one by one and efficiently.
Treatment Technology
The treatment system was structured based on an aerobic biological sewage-treatment with primary treatment, clarification, filtration, disinfection and sludge treatment.
If suitable, an MBBR based biological treatment cell configuration can be considered for such a project to provide an effective organic pollutant reduction in a relatively small area.
Why Biological Treatment?
Biodegradable organic matter is present in the domestic wastewater. Biological treatment involves treating the organic contaminants with microorganisms under controlled conditions.
Adequate aeration is available to ensure aerobic microorganisms are kept active to help degrade any biodegradable pollutant to a more stable biological material.
Treatment concept involves a combination of:
Physical Treatment → Biological Treatment → Solid Separation → Tertiary Filtration → Disinfection → Treated Water Reuse
A process was chosen that would offer a consistent treatment yet be both practical and helpful to an institutional setting.
If the plant in question is actually an SBR, MBBR, MBR, SAFF, ASP or other biological technology, the name of the technology and description of the process should be changed to the actual installed technology as part of this case study before publication.
Influent Characteristics
The wastewater received is mainly Domestic Wastewater (DW) from campus activities.
Common sources can be:
- Toilets and washrooms
- Hand-washing facilities
The following types can be considered as residential/hostel areas:
- Facilities for cooking and eating in the kitchen/dining area.
- The staff and administrative areas are kept separate.
- Housekeeping activities
Other domestic wastewater-generating facilities:
The following are parameters for wastewater that are important to consider when designing an STP:
| Parameter | Typical Design Consideration |
| Daily Flow | Up to 90 KLD |
| pH | Approximately 6.5–8.5 |
| BOD | Typical domestic sewage range |
| COD | Typical domestic sewage range |
| TSS | Variable according to sewage characteristics |
| Oil & Grease | Dependent on kitchen contribution |
| Temperature | Ambient/site dependent |
The properties of wastewater may vary depending on the type of occupancy, volume of water used, food-service activities, cleaning procedures, and how the facility is used. Therefore, the process flexibility of the treatment system should be sufficient to accept normal fluctuations without adverse effects on treatment.
In such applications, the removal of sudden changes in the hydraulic or pollutant loads which reach the biological treatment stage is especially useful, as the wastewater flow is equalized.
Treatment Process
The wastewater is fed into a series of treatment processes before it enters the storage tank for reuse.
| Process Step | Description |
| Step 1: Sewage Collection | The wastewater produced from various portions of the campus is deposited in the STP via the sewage collection network. All wastewater collected is first treated in the preliminary treatment area. |
| Step 2: Screening | Larger floating materials and other solids that might be undesirable like plastics, cloth, paper, sanitized waste, and other debris are removed using screens. Screening keeps pumps, pipelines and downstream treatment facilities from being clogged or damaged. |
| Step 3: Equalisation | The sewage is pumped into the equalisation tank after screening. The equalisation tank is important, as the wastewater produced is not necessarily even over the course of the day. Sewage is temporarily stored and blended to provide a relatively uniform flow to the biological treatment system. This helps: reduce shock loading, balance fluctuations in flow, improve biological-treatment stability, and avoid sudden load ups of downstream units. |
| Step 4: Biological Treatment | The equalised sewage is pumped into the biological treatment tank. Aerobic microorganisms break down biodegradable dissolved and suspended organic matter here. Blowers and diffusers are used to introduce air to provide oxygen to microorganisms. On the surface of the specially designed bio-media, microorganisms will be able to grow and form a biological film in an MBBR-type configuration. The microorganisms in the biological reactor eat the organic pollutants and the biodegradable pollution load is greatly decreased. |
| Step 5: Secondary Clarification | The treated wastewater then goes into a settling (or clarification) stage. The treated liquid is separated from the biological solids by gravity settling. The settled sludge is removed for additional treatment and the clarified water flows on to tertiary treatment. Good clarification reduces the amount of suspended solids, and also makes the downstream filtration more effective. |
| Step 6: Pressure Sand Filtration | Water is sent to a Pressure Sand Filter (PSF). In this stage, the residual suspended particles and turbidity that can still remain after biological treatment and clarification are removed. |
| Step 7: Activated Carbon Filtration | The water is then treated in an Activated Carbon Filter (ACF). Activated carbon can be used to enhance treated water quality as it adsorbs some residual organics and to reduce some colour and odour. |
| Step 8: Disinfection | Selected disinfection system used to disinfect the filtered water. Disinfection can be used to reduce the pathogenic microorganisms in treated wastewater, and enhance its quality for designated non-potable reuse applications. The treated water is then sent to the storage tanks. Finally, treated water is collected in a treated-water tank from where it can be pumped for approved reuse applications within the campus. |
Major Equipment
The biological treatment technology is not the only critical element for successful STP performance; selection and integration of the mechanical, electrical, and filtration equipment is also critical.
The key elements of the 90 KLD STP are equipment such as:
| Equipment | Function |
| Sewage Transfer Pumps | Depending on the plant configuration, these pumps move wastewater from collection to equalisation and from equalisation to treatment. |
| Air Blowers | The air needed for biological treatment is provided by blowers. Proper oxygen transfer is necessary to ensure aerobic microbial activity. |
| Fine Bubble Diffusers | An in-tank diffuser breaks the air into small bubbles, enhancing the oxygen transfer efficiency in the biological tank. |
| Biological Media | In an MBBR process specially designed carrier media is used that creates a great surface area for the development of attached microbial biomass. |
| Pressure Sand Filter | The PSF filters out any residual suspended matter and turbidity and acts as a tertiary filter. |
| Activated Carbon Filter | To remove residual odour, colour and some dissolved organic materials, the ACF gives polishing treatment. |
| Sludge Handling System | Settled biological solids are sent to sludge management. Sludge may be held, thickened, dewatered, or removed from the site periodically, depending on the site configuration. |
| Dosing System | Chemical dosing equipment may be supplied as needed for disinfection, pH correction or other process needs. |
| Electrical Control Panel | Electromechanical equipment such as pumps, blowers, etc. are combined with the electrical control panel. Plant operation is safer and easier thanks to the appropriate automation and protection systems. |
| Piping, Valves and Instrumentation | Pipelines are interconnected, isolation valves are used, non-return valves are installed, flow-control devices are provided, pressure gauges are installed, level controls are installed and other instrumentation are provided to allow for controlled movement of wastewater throughout the plant. |
Installation Process
The 90 KLD Sewage Treatment Plant was installed at Great Lakes Institute of Management, Gurgaon in a systematic manner during the course of a project-execution process.
1. Site Assessment
The initial phase was to be the needs assessment and identification of factors that would be an issue for installation of the project, such as:
- Sewage generation
- Available installation area
- Existing civil infrastructure
- Inlets and outlets.
- Electrical availability
- Treated-water reuse requirements
- Equipment-access requirements
The planning and operation of the building are addressed.
2. Engineering and System Planning
The treatment sequence, equipment requirements, hydraulic connections and electrical arrangements were planned based on the site conditions.
Equipment sizing was done in conjunction with the 90 KLD design capacity and the anticipated sewage characteristics.
3. Equipment Supply
The necessary pumps, blowers, diffusers, filters, piping, control systems, etc. for treatment were delivered to the project site following the installation schedule.
4. Mechanical Installation
Mechanical equipment was set-up and linked as per the process design. These included pumps, air blowers, filtration units, piping, valves and components of the biological treatment.
5. Electrical Integration
Wiring for electrical panels, power connections, motor protection systems, level-control arrangements, and equipment wiring were finished.
6. Piping and Interconnections
Process pipelines connected the various treatment units to allow for proper pipeline flow, ease of access and ability to isolate for maintenance.
7. Inspection and Pre-Commissioning Checks
The entire installation was checked prior to commissioning for:
- Pipeline leakage
- Correct pump rotation
- Blower operation
- Valve functioning
- Air distribution
- Electrical safety
- Tank levels
- Filter operation
- Control-panel functioning
This systematic approach of plant installation was helpful to make the plant ready for controlled commissioning.
Plant Commissioning
Commissioning is among the most crucial steps in an STP project as biological wastewater treatment cannot be just assessed by turning on the wastewater treatment plants.
The plant was commissioned in a progressive manner to permit evaluation of the systems – hydraulic, mechanical, electrical and biological – under operating conditions.
The activities carried out by the commission were:
- All treatment tanks and equipment to be inspected.
- Sewage-Transfer Pumps Test.
- Performance verification of air-blower.
- Inspecting the air-distribution system.
- Testing filters and pipelines connecting filters.
- Clampdown Bolster Harness.
- Valves and Electrical Controls.
- Introduction of wastewater to the treatment system.
- Development and stabilisation of biological activity.
- Aeration and operating cycle adjustment.
- Settling and clarification are observed.
- Operation of tertiary filtration in trial.
- The quality of treated water
- Plant Operator Training/guidance.
Stable performance of biological systems is obtained after a proper development and operating conditions. During commissioning, the process conditions are thus measured and optimized until the desired treatment is achieved.
Treated Water Reuse
Installing an STP is one of the most important benefits of treating wastewater instead of simply dumping it into a stream of waste.
The treated water from the 90 KLD plant following the biological treatment, clarification, filtering and disinfecting can be used for approved non-potable uses with applicable quality requirements.
Possible re-use applications are:
- Landscape irrigation
- Gardening
- Flushing
- Campus horticulture
Treated wastewater can be utilized for non-potable purposes, which decreases the need for freshwater.
This is beneficial to the environment and to the operations of a large institutional campus. Primary water used for domestic purposes can be treated and reused for appropriate secondary uses.
