Successfully Installed 40 KLD STP Plant Installation at Phoenix, NSEZ Noida

Handling of wastewater is an essential criteria for all industrial, commercial and institutional buildings, especially in the emerging industrial areas like Noida. The proper design of the Sewage Treatment Plant can not only treat effluents before releasing them into the water bodies but also allow the treated wastewater to be reused for non-potable purposes, thereby minimizing the use of freshwater for non-potable applications and promoting sustainable water management.

Being an established sewage treatment plant manufacturer in Noida, we have successfully installed a 40 KLD Sewage Treatment Plant in Phoenix, NSEZ Noida. The design of the plant is meant to treat sewage produced at the plant, and ensure consistency in treatment by means of a simple, systematic, and convenient treatment process.

The project comprised of planning, procurement of equipment, installation, pipework, electrical integration, testing and commissioning of the entire sewage treatment plant. Operational reliability, space use, treatment efficiency and routine maintenance were given special consideration.

This case study describes the project requirements, treatment process, major equipment, installation methodology, commissioning process, treated-water reuse opportunities and overall benefits of the 40 KLD STP installation.

Project Overview

The project comprised successful installation and commissioning of a 40 KLD Sewage Treatment Plant at Phoenix, NSEZ, Noida. The goal was to create one efficient wastewater-treatment process which would be capable of treating wastewater produced by the activities carried out in the premises on a daily basis.

Domestic wastewater is untreated and is found to contain suspended solids, organic matter, nutrients, microorganisms and other contaminants. Such wastewater may cause environmental issues, odour, unhygienic situations and burden existing drainage system.

The 40 KLD STP was thus designed to treat the wastewater, biologically, clarifying, filtering and dis-infecting it before re-use or proper disposal.

The project was aimed at:

Capacity of up to 40 kL per day of sewage treatment
Organic pollutants and suspended solids are reduced.
The treated water should be clearer and of a better quality.
A stable biological treatment process is provided.
Minimize odour and operating difficulties.
Promoting opportunities for reuse of treated water
Conservation of freshwater to be used for appropriate non-potable uses
Offering a small system for the limited installation space.
Enabling easier plant operation and maintenance

The installation reflects our ability as a trusted Sewage Treatment Plant Manufacturer in Noida to deliver customised sewage-treatment solutions based on the capacity, available space, working conditions and sewage-treatment needs of various plants.

Client Details

The STP was set up for Phoenix at NSEZ, Noida.

The plant had to have a wastewater treatment plant that was appropriately sized to treat the wastewater produced on site. The system had to be reliable, easy to fit and be able to run without undue complexity for the facility-management team.

The following aspects were taken into account before finalizing the system: The expected hydraulic load, treatment objectives, site conditions, wastewater generation requirement, and available space.

Considering these requirements, a 40 KLD STP was chosen as an adequate treatment capacity.

The project encompassed integration of the various treatment stages to ensure that the wastewater flowed systematically through three treatment stages, collection, biological treatment, clarification, filtration, disinfection and final treated water storage.

Project Location

Sewage Treatment Plant was installed at: Phoenix, NSEZ, Noida, Uttar Pradesh

The Noida Special Economic Zone (NSEZ) is an important industrial and commercial zone. Wastewater from the toilets, washrooms, canteen, housekeeping, and other domestic activities at these facilities must be managed in an effective manner by implementing proper infrastructure.

If an STP is installed on the premises, the wastewater can be treated in the vicinity of its production. This decentralized solution minimizes reliance on external wastewater-management solutions and opens up potential re-use of treated water on site.

Choosing a Sewage Treatment Plant Manufacturer who is well-versed in the local industrial operating conditions can also make the plant installation, plant servicing, plant maintenance and future plant modifications easy.

Plant Capacity

Sewage Treatment Plant (STP) capacity that are installed:

40 KLD – 40 Kilolitres Per Day.

It will be able to treat about 40,000 litres of sewage a day, based on the hydraulic loading and operating conditions that the plant specifies.

One of the most crucial phases in the design of an STP can be the sizing of the plant. A system that is too small can fail during times of high wastewater production, and an oversized system will mean extra capital and operating expenses.

Based on the anticipated sewage production and facility requirements, the Phoenix project capacity was chosen.

The plant design also takes into account variations in wastewater flow during different periods of the day. Typically, the generation of sewage does not happen at a steady rate all day. Peak flows can happen at work time, on break or at the end of a shift. Equalisation and controlled pumping is thus essential to achieve more even loading on the biological treatment system.

Treatment Technology

The treatment system is a Moving Bed Biofilm Reactor (MBBR)-based STP, which is a popular biological wastewater-treatment technology for compact commercial and industrial sewage-treatment applications.

MBBR treatment is based on the principle of treating water in an aeration tank with specially designed plastic media. The beneficial microorganisms grow on these media as a biofilm on the surface. In the biological reactor microorganisms decompose biodegradable organic pollutants when wastewater is introduced to the reactor.

The continuous aeration has two significant roles:

It provides oxygen needed for aerobic microorganisms. Ensures bio-film is in good contact with wastewater by moving the MBBR media around the reactor.

The MBBR system is especially beneficial in situations that need a compact biological treatment system. The large protected surface area on the media allows the growth of microorganisms which continue to allow treatment to be performed even if the characteristics of the wastewater fluctuate within the design limits of the plant.

Downstream clarification, filtration and disinfection stages are included to enhance the final treated water quality for the treatment system.

Influent Characteristics

The major component of the influent to the STP is human domestic sewage resulting from activities like washing, cleaning and sanitary operations in the facility.

Common waste products that may be added to a sewage plant include:

Biodegradable organic matter
Suspended solids
Dissolved organic impurities
Nitrogen-containing compounds
The presence of traces of oil and grease
Cleaning residues and detergents
Microorganisms and pathogens
Other contaminants that are usually found in domestic wastewater.

Some of the important parameters taken into account while analyzing sewage are: pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), oil and grease, and microbial contamination.

The true level of these parameters may vary significantly according to water consumption, occupancy, cleaning operation, canteen program and other site conditions.

Therefore, actual plant design data and wastewater-analysis reports should be used to base plant design and operation, rather than a single design composition being assumed.

The 40 KLD system was designed to offer numerous treatment barriers to enable the progressive reduction of the physical solids, biodegradable pollutants, suspended matter and microbial contaminants at successive treatment stages.

Treatment Process

The 40 KLD STP is a sequential treatment facility with a treatment sequence to treat raw sewage to the required treated effluent quality for the intended use or discharge.

The typical process flow of the installed system is:

Raw Sewage → Screening → Collection/Equalization → Biological Treatment → Clarification → Treated-Water Storage → Pressure Sand Filtration → Activated Carbon Filtration → Disinfection → Final Treated Water

Process Step	Description
Screening	The first step in the wastewater treatment system is through a screening process. Screening is designed to catch large floating and suspended substances like plastics, fabrics, paper and junk. This action will prevent damage or blocking of downstream pumps, pipelines and treatment equipment.
Collection and Equalization	Sewage is fed into collection or equalisation tank after preliminary screening. The equalization stage helps to equalize fluctuations in wastewater flow and pollutant concentration. By allowing the wastewater to enter the biological treatment system at a more controlled rate, sudden hydraulic surges will not enter the system. Depending on the system design, mixing or aeration can also be provided to minimize septic conditions and keep the wastewater in a relatively homogeneous condition.
Biological Treatment	The equalized sewage is pumped to the biological treatment area. An MBBR process uses specially designed bio-media, which are kept in an aerated reactor. Biodegradable organic pollutants in sewage are removed by microorganisms attached to the media. Media is kept moving and aerobic conditions are maintained throughout by air supplied from blowers and diffusers. This phase is mainly responsible for the minimisation of biodegradable organic contaminants and is, therefore, one of the most crucial processes of the STP.
Clarification	The biological treatment effluent includes biological solids which must be removed from the treated water. The clarification stage offers conditions for settling the suspended biological solids and obtaining a clearer supernatant. Sludge collected is dealt with on a regular basis based on the plant design and operating procedure.
Treated-Water Storage	The clarified wastewater goes to an intermediate treated-water tank. This allows storage prior to tertiary treatment and allows the filtration system to function in a controlled pumping condition.
Pressure Sand Filter	The Pressure Sand Filter is tertiary treatment unit in which fine suspended particles which have not been removed during biological treatment and clarification processes are removed. Filtration enhances the physical quality and clarity of the water and decreases remaining suspended solids.
Activated Carbon Filter	Water from the sand filter is then fed into an Activated Carbon Filter. Activated carbon can be used to enhance the quality of treated water by adsorbing some dissolved organic compounds and compounds that contribute to water colour and odour.
Disinfection	The last treatment step is disinfection either by a dosing or disinfection system. Disinfection is so crucial for the reduction of microbial contamination before treated water is reused and/or discharged properly. After disinfection, the treated water is stored in a final storage facility and can be used for appropriate non-potable uses.

Major Equipment

A Sewage Treatment Plant can only perform satisfactorily if the mechanical, electrical, biological and filtration systems work as a whole.

The main equipment used in a typical 40 KLD STP system is:

Equipment	Function
Sewage Transfer Pumps	To convey sewage from one stage to the next in the collection, equalization, biological, and treatment process.
Air Blowers	Provide the oxygen for the aerobic biological treatment. Blower selection is crucial to maintaining dissolved oxygen and good biological activity.
Fine-Bubble Diffusers	These are fitted in the biological tank to spread the air evenly throughout the wastewater.
MBBR Media	High surface area media to grow the microorganisms as biofilm.
Settling/Clarification System	Remove the biological solids from treated wastewater after biological treatment.
Filter Feed Pumps	Feed clarified water at the required pressure to tertiary filters.
Pressure Sand Filter	Eliminates the fine suspended impurities that can not be removed by the clarifier.
Activated Carbon Filter	Reduces odour, color and some type of dissolved organic materials.
Disinfection System	System for controlling microbial contamination prior to treated-water reuse.
Piping	Connect treatment units and facilitate correct flow, isolation and access for maintenance of piping.
Electrical Control Plant	Used to control pumps, blowers and other electromechanical equipment, and to systemically operate the plant.
Level-Control System	Automates the operation of the pumps and prevents tank overflow or dry running.

Selection of equipment was undertaken while considering equipment capacity, reliability, operating requirements, maintenance requirements, etc.

Installation Process

Installation of 40KLD STP at Phoenix, NSEZ, Noida was done in a planned sequence to ensure proper integration of civil, mechanical, piping and electrical components.

1. Site Assessment

The installation process started with a site assessment of the available space for the STP, access to the site, arrangement of sewage inlet, treated water outlet, electrical availability, pipe routing, and equipment placement.

2. Equipment Positioning

Equipment was arranged in the sequence of the treatment processes. Wherever possible, sufficient access was provided for inspection, operation, servicing and routine maintenance.

3. Mechanical Installation

Pumps, blowers, filters, diffusers, piping accessories, valves and others were installed and connected as per process design.

Special consideration was given to the alignment of equipment and routing of pipes.

4. Piping Integration

Pipe connections were made between the various tanks and treatment units.

Valves were installed at suitable points to allow for equipment and pipelines to be isolated for maintenance or inspection.

5. Electrical Work

The plant control system was used to provide power connections to pumps, blowers and electrical equipment.

Before trial operation, the control wiring, protection systems, level-based operation and equipment switching arrangements were checked.

6. System Inspection

After installation, mechanical and electrical systems were checked for potential leaks, wrong connections, loose parts, wrong direction of flow and electrical problems.

These checks were performed before the plant could be commissioned.

Plant Commissioning

Commissioning is a necessary step as it is not enough to turn on the pumps and blowers.

The 40 KLD STP was commissioned, which required the whole treatment system to be systematically tested.

The first step was to inspect individual pieces of equipment such as pumps, blowers, control panels, valves and filters for correct operation.

Water trials were carried out to check:

Pump functioning
Flow direction
Pipeline integrity
Valve operation
Tank connectivity
Air distribution
Filter operation
Electrical controls
Level-control functions
Leakage or Abnormal Vibration

Biological system involves the development and stabilisation of microorganisms for treatment of the wastewater. The aeration conditions, loading of water waste, characteristics of sludge and operation of the plant thus have to be monitored in the stabilization period.

After a stable biological environment was established, the entire treatment system from the inlet to final collected treated water was reviewed.

The operating personnel were also trained on the normal plant operation, routine inspection, cleaning needs, sludge management, and filter operation and preventive maintenance.

Treated Water Reuse

A significant benefit of having an STP is the opportunity to re-use treated wastewater rather than using fresh water to each and every application.

Water from the 40 KLD STP may be used for appropriate non-potable purposes including but not limited to:

The landscaping irrigation and gardening are well done.

Toilet flushing
Floor washing
Paved areas are cleaned.
General housekeeping
Any other approved non-potable utility applications

Treated-water recycling can contribute significantly to water conservation.

For instance, if a significant portion of the treated water is recycled within the premises, the plant’s need for fresh water for gardening, flushing, or cleaning can be decreased.

Recycling also promotes a more circular management of water, as the wastewater can be seen as a resource to be recovered rather than a waste stream.

When deciding on the final use of treated water, the quality of the water verified by the test results should always be considered as well as environmental or regulatory application parameters.

Results and Performance

After the completion of 40 KLD STP installation in Phoenix, NSEZ Noida, the facility was equipped with an organized wastewater-treatment system, which will collect and treat sewage produced on its premises.

The plant that is already installed offers a number of operational and environmental benefits.

Result	Description
Reliable Wastewater Treatment	This multi-stage treatment system consists of preliminary, biological, clarification, tertiary filtration, and disinfection, which enable more efficient sewage treatment than a single stage system.
Prevention of Organic Pollution	Biological treatment will lower the amount of biodegradable organic pollutants found in wastewater. This has a significant impact on the quality of water prior to the use for tertiary treatment and reuse.
Improved Water Clarity	Clarification by pressure sand filtration process yields treated water with improved clarity due to removal of suspended solids and fine particles.
Better Odour Control	Aeration and biological treatment will ensure the sewage does not stay in uncontrolled septic conditions and aid in better odour control.
Water Conservation	Treated water may be used for certain non-potable purposes, thus conserving fresh water.
Compact Treatment Solution	The treatment process is appropriate for plants where plant space is limited and the wastewater needs to be treated effectively.
Operational Convenience	Regular operation and maintenance of the plant are easier because of the proper equipment layout, valves, pumps, control systems, and filtration arrangements.
Sustainable Wastewater Management	The plant’s treatment at the point of generation and reuse of the treated wastewater helps the facility become more responsible and sustainable with water.

Actual plant performance should be recorded by periodic laboratory testing of inlet and treated-water samples. Parameters of pH, BOD, COD, TSS, oil and grease and microbiological indicators may be monitored based on operating and compliance needs of the facility.

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.

Results and Performance

After the installation and commissioning the 90 KLD Sewage Treatment Plant (STP) set up a system for managing sewage generated at the Great Lakes Institute of Management (GLIM) Gurgaon campus.

The outcomes of the major project are:

Result	Description
Reliable Wastewater Treatment	Instead of untreated sewage becoming an environmental or sanitation issue, the plant offers an organised solution to sewage treatment.
Reduction of Organic Pollutants	Biological treatment decreases biodegradable organic matter from domestic sewage.
Reduced Suspended Solids	Suspended particles are removed and the physical quality of treated water is improved through clarification and filtration.
Improved Water Clarity	An extra step of fine suspended material removal is made available by pressure sand filtration.
Improved Odour and Colour Characteristics	Activated-carbon polishing can enhance aesthetic properties of treated water.
Treated-Water Recovery	The treated water can be reused for appropriate non-potable applications, thus lowering the need for freshwater supply.
Compact and Handy Operation	The treatment arrangement is an efficient solution which can be adopted in the institutional environment when space and ease of operation are important.
Support for Sustainable Campus Operations	The institution can effectively utilise available water resources and minimise environmental impacts due to untreated wastewater by treating and recovering it.

CPCB_Guidelines_for_Common_Effluent_Treatment_Plants.jpg

The Ministry of Environment, Forest and Environmental Change has advised the updated CPCB Guidelines for Common Effluent Treatment Plants (CETPs) working at different industrial clusters in the country. The primary point of the revised standards is to minimize water contamination. These standards were finalized after extensive consultations with industries and different partners and detailed deliberations with the Central Pollution Control Board (CPCB). The changed norms were notified on January 1, 2016. The changed norms will help fundamentally work on the performance of CETPs through the implementation of design inlet quality, resolving the issues of coastal pollution because of industrial discharges, and keeping a close watch on the effect of the release of industrial effluent on soil and groundwater quality.

The Guidelines given for CETP by CPCB Guidelines for Common Effluent Treatment Plants are as per the following:

CPCB Guidelines for Common Effluent Treatment Plants

1- The Centre has advised the revised standards for Common Effluent Treatment Plants (CETPs) working at different industrial groups in the country with an aim to minimize water contamination.

2- The Environment Ministry notified the norms which were concluded after broad counsel with industries and other partners and point-by-point thoughts with the Central Pollution Control Board (CPCB).

3- “The Environment Ministry has notified the revised standards for Common Effluent Treatment Plants (CETPs) working at different industrial groups in the country. The primary point of the revised standards is to minimize water contamination,” an official statement said today, adding that the revised standards were notified on January 1.

4- The revised standards will help in essentially working on the performance of CETPs through the implementation of design inlet quality, addressing the issues of coastal contamination because of industrial discharges.

5- It will also help in further improving the CETP’s performance by close watch on the effect of the discharge of industrial effluent on soil and groundwater quality.

6- Under the revised standards, an provision of soil and groundwater quality checking two times per year (pre-and post-monsoon) has been introduced.

7- This has been introduced with a concentrate on the effect of removal of treated effluent on land, in case of the method of removal is ‘on land for irrigation’ and the monitoring will be done by the separate CETP management.

8- “The method of ‘Discharge into the ocean’ (marine outfalls) giving extremely high dilution will qualify all requirements for a relaxed maximum permissible concentration of Chemical Oxygen Demand (COD).

9- “The maximum permissible concentration of Fixed Dissolved Solids (FDS) by constituent units to CETP has been determined as far as maximum admissible contribution value,” the statement added.

10- Status report by the Central Pollution Control Board (CPCB) consistent with the National Green Court order May 21, 2020, in Original Application No. 593/2017 (Paryavaran Suraksha Samiti and Others Vs Union of India and Others) with Original Application No. 148/2016 (Mahesh Chandra Saxena Vs South Delhi Municipal Corporation and Others).

11- The report of September 16, 2020, contained the state-wise consistency status of all industries generating trade effluent and requiring effluent treatment plants (ETP) – as reported by the state pollution control board (SPCB)/pollution control committee (PCC). According to the information got from SPCBs/PCCs:

Out of a total 64,484 number of industries requiring ETPs, 62,653 industries are working with functional ETPs and 1,831 industries are working without ETPs.
61,530 industries are complying with environmental norms and 1,123 industries are noncomplying.
There are a complete 191 CETPs, out of which 129 CETPs are agreeing with environmental standards and 62 CETPs are non-complying.
There is a total of 15,730 STPs (including municipal and other than municipal (non-municipal/independent) STPs), out of which, 15,200 STPs are agreeing with environmental guidelines and 530 STPs are non-complying.
There are 84 CETPs in the construction/proposal stage, whereas, for STPs, 1,081 tasks (municipal and non-municipal) are under the construction/proposal stage.

The report also contained an assessment of the effect of the lockdown on the water quality of major rivers. During the pre-lockdown period (March 2020), SPCBs gathered samples from 388 locations through 366 samples from the checking locations during lockdown (April 2020) from 19 major rivers, and collected samples were analyzed for Primary Water Quality Measures for Washing Water Quality Standards notified under the Environment (Protection) Rules, 1986.

CPCB Common Effluent Treatment Plant

According to the legal guidelines for Sewage Treatment Plants given by CPCB, different infrastructures like Apartments, Commercial Development Projects, Educational Institutions, Municipalities, and Area Advancement Undertakings meeting specific models need to introduce STPs for the treatment of sewage that they produce, and every sewage treatment plant manufacturer have to follow it.

The guideline rules cover angles in regards to the area of STPs, the STP technology to take on, working as well as its maintenance to guarantee effective and safe activity of the machinery.

The Guidelines given for STPs by CPCB Guidelines for Sewage Treatment Plants are as per the following:

CPCB Guidelines for Sewage Treatment Plants

Activated Sludge Process (ASP) (just when over 500 KLD sewage is generated).
Membrane Bio Reactor (MBR)
Moving Bed Bio Reactor (MBBR)

2. Unit Requirements of STP

STPs have different individual units where different sewage treatment processes happen. The units and their criteria according to the guideline’s prerequisite are as per the following.

SNo.	Unit	Activated Sludge Process (ASP)	Sequential Batch Reactor (SBR)	Membrane Bio Reactor (MBR)	Moving Bed Bio Reactor (MBBR)
1	Equalization Tank	Should have a minimum holding period of 8 hours	Same as ASP	Same as ASP	Same as ASP
2	Anoxic Tank	Return activated sludge should be pumped to anoxic tank for denitrification.	Not Required	Same as ASP	Same as ASP
3	Aeration Tank	Dissolved Oxygen in an excess of 4 mg/L has to be maintained in the Aeration Tank.	Same as ASP	Same as ASP	Same as ASP
4	Membrane Tank	Not Required	Not Required	Membranes should be replaced regularly as per its manufacturer’s specifications	Not Required
5	Sludge Holding Tank	Sludge holding should be madatoriliy provided for holding excess sludge before its dewatering.	Same as ASP	Same as ASP	Same as ASP
6	Final Treated Water Holding Tank	Capacity of the tank should be enough to hold water for 2 days minimum.	Same as ASP	Same as ASP	Same as ASP
7	Sludge Drying Bed	Instead of sludge drying bed, horozontal centrifuge system should be used for >500KLD STPs. For <500 KLD STPs, belt press or screw press system should be used.	Same as ASP	Same as ASP	Same as ASP

3. Mechanical Equipment Requirement for STP

There should be a clear and simple access to the Bar Screen Chamber and Oil and Grease Chamber of STPs introduced. Likewise, the supplies should to be of the submersible sort with a simple removal/it is expected to destroy choice at whatever maintenance is required.

Air blowers of STP should to have Vibration mounts and acoustic fenced-in areas to diminish noise pollution.

4. Location of STP

STP should to be situated under the driveway, play area, or clubhouses, and distant from the residential housings to not make any subtlety individuals living.

Additionally, STP should not be installed in that basement of any structure or building. Admittance to the STP room should to be from Ground Level or Upper Basement through all around designed walkways or headroom, and not from the lowest basement to stay away from subtleties that might occur because of rain flooding, smell or sound.

5. Treated Sewage Standards

The sewage treated should meet the following standards.

S NO.	Parameter	Required Standards
1	pH	6.5-8.5
2	BOD(5^th Day)	<10mg/l
3	COD	<50mg/l
4	Suspended Solids	<10mg/l
5	Ammonical Nitrogen	<5mg/l
6	Total Nitrogen	<5mg/l
7	Fecal Coliform	<100MPN/100ml

6. Guidelines for installing sensors

It’s compulsory to introduce sensors for observing sewage parameters like BOD, COD, TSS, stream, and pH.

The CPCB suggested sensor types with their correspondence conventions are as per the following.

S. No.	Parameter	Measurement Type	Sensor Type	Communication Type
1	pH	Inline	Ion Selective Glass Electrodes	RS 485 Communication with Modbus
2	TSS	Inline	Turbidity to TSS correlation with Nephelometric technique	RS 485 Communication with Modbus

5	Flow	Inline	Electromagnetic Flow Measurement	RS 485 Communication with Modbus

7. Caution Board at STP

Legitimate preventative billboards should to be displayed and security conventions should to be followed at the STP locations.

“Danger” Sign Sheets should to be introduced at the STP area for the maintenance personals and general public. What’s more “water not well for drinking” should to likewise be featured at the taps conveying sewage water.

8. Use of Treated Sewage

The treated water should to be compulsorily utilized for toilet flushing purposes that should to have a double pipes system.

9. Modular Operations of STPs

Modern activity of STPs suggests that the STP should to be created/developed in smaller units so it tends to be utilized according to the heap or inhabitance of individuals. In huge tasks where a higher limit of STPs required, the inhabitance in the underlying stages can’t meet the functional measures of the STP Plants. Thus, the component should to be viewed as in the plan stage itself.

Untreated wastewater shouldn’t accumulate in any way. It consists of perished organic matter. However, these accouterments can produce a huge amount of foul-smelling gases that can be poisonous to the terrain, If kept for a while. Besides this, it also contains other poisonous composites that can be dangerous if exposed to the terrain for a long. thus, it’s important to remove wastewater from its source and clean it. also, due to the failure of water, exercise is an excellent option. Do you know Which is most Commonly Used Sewage Treatment Plant in India?
With time, MBBR technology become the most Commonly Used Sewage Treatment Plant in India, has come to an established process for wastewater treatment due to the advanced and innovative technology it uses and the cost of Moving Bed Biofilm Reactor which has reduced drastically down as compared to the other technology. As per the combined query of Quality, Technology, and Cost, MBBR is one of the most considered sewage treatment plants in India.

MBBR Sewage Treatment Plant

The Moving Bed Biofilm Reactor( MBBR) wastewater treatment process was first constructed in the late 1980s.
The MBBR process has an aeration tank with plastic transporters filled with wastewater. This gives way to the growth of biofilm. The viscosity of these carriers and water is the same. generally, activated sludge systems bear recycling of the sludge, which isn’t the case in the MBBR process.
It’s considered to be a better option as compared to other conventional styles.

Benefits of MBBR Sewage Treatment Plant

Complete solid junking
Smaller units require lower space
Increased process stability
Increased treatment volume
Periodic backwashing isn’t required
Sludge product is dropped
Advanced settling characteristics
Accessible to use
Reliable and effective
Cost-effective

Working of Sewage Treatment Plant

Wastewater Plant (STP Plant) is treated in 3 phases primary( solid removal), secondary( bacterial decomposition), and tertiary( extra filtration).

Common Key Terms in wastewater/ sewage treatment

Primary Treatment is the first phase of sewage treatment wastewater is placed in a holding tank and solids settle to the bottom where they’re collected and lighter substances like fats and oils are scraped off the top.
Secondary Treatment is where waste is broken down by aerobic bacteria incorporated into the wastewater treatment system.
Tertiary Treatment is designed to filter out nutrients and waste particles that might damage sensitive ecosystems; wastewater is passed through fresh filtering lagoons or tanks to remove redundant nutrients.
Effluent Sewage water that has been incompletely treated and is released into a natural body of water; an inflow of any liquid waste.

Sewage is generated by domestic and industrial establishments. It includes household waste liquid from toilets, baths, showers, kitchens, cesspools, and so forth that’s disposed of via seamstress. In numerous areas, sewage also includes liquid waste from assiduity and commerce. The separation and draining of ménage waste into greywater and blackwater are getting more common in the advanced world. Greywater is water generated from domestic conditioning similar to laundry, dishwashing, and bathing, and can be reused more readily. Blackwater comes from toilets and contains mortal waste.

Sewage treatment is done in three stages primary, secondary and tertiary treatment.

Primary Treatment
In the primary treatment of STP Plants, sewage is stored in a basin where solids( sludge) can settle to the bottom and oil painting and lighter substances can rise to the top. These layers are also removed and also the remaining liquid can be transferred to secondary treatment. Sewage sludge is treated in a separate process called sludge digestion.
Secondary Treatment
Secondary treatment removes dissolved and suspended biological matter, frequently using microorganisms in a controlled terrain. utmost secondary treatment systems use aerobic bacteria, which consume the organic factors of the sewage( sugar, fat, and so on). Some systems use fixed film systems, where the bacteria grow on pollutants, and the water passes through them. Suspended growth systems use “ actuated ” sludge, where putrefying bacteria are mixed directly into the sewage. Because oxygen is critical to bacterial growth, sewage is frequently mixed with air for grease decomposition.
Tertiary Treatment
Tertiary treatment( occasionally called “ effluent polishing ”) is used to further clean water when it’s being discharged into a sensitive ecosystem. Several styles can be used to further disinfect sewage beyond primary and secondary treatment. Beach filtration, where water is passed through a beach sludge, can be used to remove particulate matter.

Wastewater may still have high situations of nutrients similar to nitrogen and phosphorus. These can disrupt the nutrient balance of submarine ecosystems and beget algae blooms and inordinate weed growth. Phosphorus can be removed biologically in a process called enhanced natural phosphorus junking.

In this process, specific bacteria, called polyphosphate accumulate organisms that store phosphate in their tissue. When the biomass accumulated in these bacteria is separated from the treated water, these biosolids have a high toxin value. Nitrogen can also be removed using nitrifying bacteria. Lagoon is another system for removing nutrients and waste from sewage. Water is stored in a lagoon and native plants, bacteria, algae, and small zooplankton sludge nutrients and small particles from the water.

Sludge Digestion

Sewage sludge scraped off the bottom of the settling tank during primary treatment is treated independently from wastewater. Sludge can be disposed of in several ways. First, it can be digested using bacteria; bacterial digestion can occasionally produce methane biogas, which can be used to induce electricity. Sludge can also be incinerated, condensed, hatted to disinfect it, and reused as a toxin.

Now you will get all the details of the commonly used sewage treatment plant in India. You can ask any question if you have any.

Are you or your organization is planning for STP Plant, and stuck with the best technology of sewage treatment plant. No worries!! You are in right place, in this article we are going to discuss the best technology of STP its advantages, and every minor to major information that you want to know before buying a Wastewater treatment plant.

In recent times there is a number of new waste and wastewater treatment technology that have come into practice. The following are some better known and best Sewage Treatment Plant Technology–

Membrane Bio-Reactor (MBR)

MBR is the best technology of STP, wherein water treated by biological process. After the biological process treated water passed through Membrane Bio-Reactor Module.

Advantages of Membrane Bio-Reactor

High-quality effluent for reuse without separate nutrient removal and fine filtration
A compact system reduces plant footprint by 25-40% compared to a conventional STP.
These membranes are stated to be durable to ensure reliability and long membrane life, and low membrane replacement frequency.
The modular system is expandable
Higher stability to organic shocks /upsets due to higher MLSS concentration.
The process operates under low suction, the ideal filtration method for small to large-scale membrane facilities, hence low power consumption.
An automated system makes the process operations easier to operate.

Disadvantages of Membrane Bio-Reactor

Each vendor advocates his own criteria for the membranes and their types which makes it difficult to bring about common and validated design criteria.
It is not possible to cannibalize the system between different manufacturers.
High reliance on energy input in the absence of biomethanation.
Patented process technology and decanters defying local cannibalization.
Detailed evaluation of existing plants required either by IITs, CPCB, or NEERI.

Moving Bed Bio Reactor (MBBR) / Fluidized Aerobic Bioreactor (FAB)

MBBR can also be considered as the optimum technology to treat wastewater, as the cost of MBBR is cheaper and consumable cost is economic in comparison to MBR Technology.

Advantages of MBBR

There are no limitations of height as long as compressors can be suitably used
Circular structures can be used to economize on construction costs & time
The structures can be easily covered for indoor air quality when needed.
Requires lower footprints compared to conventional activated sludge.
Easy to operate and maintain

Disadvantages of MBBR

The area per unit volume of the media offered by various vendors are different and also each vendor advocates his own criteria for the relative ratio of the volume of media to volume of aeration tank, which makes it difficult to bring about common and validated standard design criteria. The quality of plastic media varies.
The verification of whether the media is moving about the entire volume of the tank or merely clumping at the top layers and if so the method of mixing it up through the tank volume without shearing of the biomass on it are issues of infirmity and which may need gentle movers of the media through the volume of the tank.
Furthermore, the media is a patented product.
Higher energy input if used without biomethanation

Sequencing Batch Reactor (SBR)

SBR Does not require separate secondary clarifiers and major return sludge pumping stations, good use of common walls, Simple Square, rectangular or circular structures, can reduce the footprint compared to 5 conventional activated sludge processes.

Advantages of Sequencing Batch Reactor

Can remove N and P concurrent with BOD
Absence of odor and corrosive gases
Improved aesthetics
Capability to manage and treat variable loading conditions; such as normal, diurnal, dilute monsoon and shock loads.
Less manpower due to automatic control and easy to operate and to maintain.
High-quality effluent for reuse without separate nutrient removal and fine filtration.
Can be expanded as a modular system.
Can also be used with primary clarifiers and conventional F/M ratio for bio-methanation and energy recovery.
The system can generate a stabilized sludge.

Disadvantages of Sequencing Batch Reactor

No provision for sludge management
No provision of primary treatment to moderate pollution load variations
Higher energy input if used without bio-methanation
Requires at least semi-skilled manpower
Patented process technology and decanters defying local cannibalization

Why Choose MBR Technology to Optimize Your Sewage Treatment Process

One of the easiest and most effective ways to optimize existing biological systems is integrating a moving bed reactor process (MBR). These systems take aspects of two other treatment systems to utilize their advantages without their disadvantages.
This technology does not require recirculation lines.
This is one of the benefits of MBR fixed film systems. Recirculation requires extra piping and additional pumps and energy, therefore, there are no extra costs associated with these additional recirculation processes.
Processes that require recirculation also typically produce more sludge in the clarifying step, more sludge that will need to be disposed of. This also means that the overall efficiency of the reactor is not dependent on how well the effluent settles. There is also the possibility of improving the efficiency of sludge recycling processes.
MBR systems improve the characteristics of sludge settling in the clarifier and the sludge settles better as well.
The moving bed technology also has improved retention times when compared to other biological sewage treatment processes.
