2.7 Sewerage Treatment and Disposal

As per water balance diagram, 1,125 kl/d sewage will be generated after the

proposed development at Pune Civil Enclave which will be treated in STP of

two modules of 600 kld capacity each (total treatment capacity 1200 kld).

2.8 Sewage Treatment Plant

Sewage generated from the airport will be treated in well-designed Sewage

Treatment Plant (STP). It is proposed to installed Moving Bed Biofilm

Reactor (MBBR) type sewage treatment plant of two modules of 600 kld

capacity each (total treatment capacity 1200 kld).



Design of STP

As per water balance diagram, 1,125 kl/d sewage will be generated after the

proposed development at Pune Civil Enclave which will be treated in STP of

two modules of 600 kld capacity each (total treatment capacity 1200 kld).

Sewage will be collected and treated in well-designed sewage treatment plant.

After meeting stipulated standards, treated waste water will be utilized for

flushing purpose, irrigation of greenery and landscaping.

Details of Sewage Treatment Process

The sewage from the proposed airport shall be collected by gravity into the

collection tank/equalization tank of Sewage Treatment Plant (STP) via

perforated screens to prevent the large particles into system. In equalization

tank, pH and temperature of incoming sewage will be equalized. The sewage

from equalization tank will be pumped to Moving Bed Biofilm Reactor (MBBR)

reactor for biological treatment, where required quantity of air in presence of

MBBR system will be supplied to meet the oxygen requirements by mean of

blower and fine bubbles air diffusers. After MBBR reactor, sewage will flow by

gravity to settler (tube type) where sludge will be settled at the bottom due to

gravity. This settled sludge will be recycled through sludge pump to MBBR

reactor to meet the mixed liquor suspended solids (MLSS) requirement, excess

sludge will be discharged through filter press for final disposal. Final discharge

of waste water from settler will be collected in chlorine contact tank, where some

chlorine will be dosed for disinfections of treated waste water. Then, treated

sewage will be pumped for tertiary treatment through duel media filter or it will

be passed through or it will be passed through Ultraviolet (UV) disinfection

system. Treated sewage will meet the norms prescribed by State Pollution

Control Board and will be utilized for flushing, HVAC and for irrigation of

greenery & landscaping purpose. Treated wasted water will not be discharged

out side the boundary of proposed airport.

Design Parameters

Design parameters for the proposed STP are given below:

Sl. Parameters Inlet Outlet

1. BOD 300 mg/l Less than 20 mg/l

2. COD 400 mg/l Less than 150 mg/l



3. Oil & Grease 50 mg/l Less than 10 mg/l

4. TSS 200 mg/l Less than 50 mg/l

5. PH 6.5-8.5 mg/l 6.5-8.5 mg/l

No treated waste water will be discharged outside the airport. Unit wise

description of the proposed STP is given below and shown in Figure 2.2:

Screen Chamber

Prior to the actual treatment of the wastewater, a screen chamber will be

provided. In this chamber removable type mechanical bar screens will be

provided for removal of various large size elements, such as paper, cloth,

plastic etc, etc, which may hamper the satisfactory functioning of subsequent

units of the STP, if not removed at early stages.

Oil & Grease Trap

The oil & grease trap will be provided to collect oil and grease trace coming with

sewage. Collected oil & grease will be stored in a drum and disposed of in

environmental sound manner.

Equalization Tank

As the quantity of the flow is non-uniform in nature, an equalization tank will

have to be provided. By the provision of an equalization tank, wastewater

characteristics will become homogeneous in nature and, therefore, better

treatment can be achieved in the subsequent units of the STP. Diffused

aeration will be provided in this tank to stir the contents of the tank completely.

MBBR Reactor (Biological Treatment)

Moving Bed Biofilm Reactor (MBBR) technology employs thousands of

polyethylene biofilm carriers operating in mixed motion within an aerated

wastewater treatment basin. Each individual bio carrier increases productivity

through providing protected surface area to support the growth of heterotrophic

and autotrophic bacteria within its cells. It is this high-density population of

bacteria that achieves high-rate biodegradation within the system, while also

offering process reliability and ease of operation.

This technology provides cost-effective treatment with minimal maintenance

since MBBR processes self-maintain an optimum level of productive biofilm.



Additionally, the biofilm attached to the mobile biocarriers within the system

automatically responds to load fluctuations.

The bacteria/activated sludge grow on the internal surface of the carriers. The

bacteria break down the organic matter from the waste water. The aeration

system keeps the carriers with activated sludge in motion. Only the extra

amount of bacteria growth, the excess sludge will come separate from the

carriers and will flow with the treated water towards the final separator. The

system can consist of a one stage or more stage system (see underneath

schedule), depending on the specific demands. The specific bacteria remain in

their own duty tank because of the fact that the carriers remain in only 1 tank,

protected by screens.

A bio-film develops on the media, which move along the effluent sewage in the

reactors. The movement within the reactors is generated by providing aeration

with the help of diffusers placed at the bottom of reactors. This thin film on the

media enables bacteria to act up on the bio-degradable matter in the effluent

sewage and thus reduce the BOD/COD content in presence of oxygen from the

air used for fluidization. Aeration will be done with the help of twin lobe blowers.

The MBBR reactors will increase the oxygen content of the sewage and thus,

will help in the growth of the micro-organisms required to reduce the BOD.

These micro-organisms will consume the organic matter and will convert it into

active biomass, better known as sludge. The waste water, laden with sludge,

will be transferred to tube settler for sludge separation.

Secondary Settling Tank Followed by Pre filtration Tank

The sludge formed will settle in the secondary settling tank followed by pre

filtration tank. The settled sludge will be discharged in the Sludge Collection

Tank and would be dewatered using sludge press. The clear supernatant from

the outlet of the tube settler will be discharged as treated waste water and will

be passed on to further treatment for final polishing. HDPE/PVC low

maintenance tubes will be provided for trouble free operation of the tube settler.

Sludge Filter Press

The sludge from the settling tank of the STP will be collected in the tank and

will be treated in the sludge press. This will be 24 plates CI sludge press

completes with its pump and accessories. In sludge press, the sludge in the



form of liquid slurry is fed into the press and dry solid cake of sludge is taken

out from it. These dry cakes are used as manure for green belt and landscaping.

Pressure Sand Filter

For final polishing of the treated waste water, a Pressure Sand Filter (PSF) will

be provided. The PSF comprises of a MS Vessel having filtering media sand

topping for filtration of supernatant treated sewage water and thus ensuring

clarity of water.

Activated Carbon Filter

For tertiary treatment, an Activated Carbon Filter (ACF) will be provided. This

will be MS constructed tank in which activated charcoal/carbon will be filled as

adsorbing media. This will not only adsorb impurities but will also act as the

polishing tank for the final treated waste water. The resultant water shall be

clear, odourless and will be reused for horticulture purpose.

Ultraviolet (UV) Disinfection System

Ultraviolet (UV) disinfection will use a UV light source. UV-rays are energy-rich

electromagnetic rays that are found in the natural spectrum of the sunlight. They

are in the range of the invisible short wave light having a wavelength ranging

from 100 to 400 nm. can pass through a flow chamber, and UV rays are

admitted and absorbed into the stream. When ultraviolet energy is absorbed by

the reproductive mechanisms of bacteria and viruses, the genetic material is

rearranged and they can no longer reproduce. They are therefore considered

dead and the risk of disease has been eliminated.

UV plant will have following features:

Stainless steel construction

Single lamp

Long life of the UV Lamp



2.9 Rain Water Harvesting

Rainwater harvesting system for proposed terminal building will be developed

based in Central Ground Water Board (CGWB) Guidelines and Construction

4.1 Energy Conservation Measures

During design, construction and operation phases of proposed development of

Pune Civil Enclave necessary measures will be taken for conservation of

energy in line with “Energy Conservation Building Code –2016” and “National

Building Code 2016”. The important energy conservation measures proposed

for new terminal building are described below:

Optimized Building Orientation in the Plot

Insulated Walls & Roof

High Performance Glazing

Building Shading Devices

High Efficiency Chillers, Demand Control Ventilation, Heat recovery

Wheel, VFDs

Energy Efficient LED Lighting

Occupancy Sensors and Dimmers

It is proposed that 100 KW solar power generation plant will be established at

the airport to produce clean energy.

By adopting above measures about 40% energy will be saved.
