8. SEWAGE TREATMENT TECHNOLOGY

Existing STP based on SAFF Technology. 2 NO. Of STP with capacity of 500 KLD & 300 KLD in

operation and expansion STP based on MBBR Technology with capacity of 100KLD.

SUBMERGED AEROBIC FIXED FILM TECHNOLOGY

Submerged Aerobic Fixed Film Reactor (SAFF) is a cost-effective method of waste water treatment and

sewage sanitation that is primarily used in residential and commercial complexes. It is based on aerobic

attached growth process and used in the secondary treatment of wastewater treatment plant. SAFF

process is attached growth type aerobic biological process which uses corrugated inert UV stabilized

PVC media. Unlike other aerobic processes of suspended growth principally it provides higher

mechanical surface area due to corrugation on media surface. This higher surface area helps biomass

microbes for rapid digestion of biomass. In the wastewater industry, SAFF Technology is used

commonly for commercial and residential sewage sanitation / waste water treatment, particularly for

small to medium range flow requirements.

In this process raw sewage is introduced into the SAFF Reactor where attached growth process takes

place containing contains polymer based bio-media. The aerobic environment in the SAFF is achieved

by the use of fine bubble diffused aeration equipments, which also serves to maintain the mixed liquor

in a completely mixed regime. The mixture of new cells and old cells overflows into a secondary

sedimentation tank where the cells are separated from the treated wastewater. A portion of the settled

cells is recycled using the horizontal, non-clog, and flooded pumps to maintain the desired concentration

of organisms in the SAFF reactor and the remaining portion is wasted to aerobic sludge digester-cum-

thickener tank for further sludge treatment. The air for process is supplied through mechanical aeration

system arrangement which consist of blower and diffusers. The structured SAFF media arranged in

reactor is fixed with bottom support arrangement.

MBBR TECHNOLOGY

In operation phase of the project and same will be treated by captive MBBR based 1 NO. of STP of

100KLD. STP Treated water will be used for Flushing, horticulture and road washing and surplus

amount of treated water will be disposed to municipal sewer line or construction activities. It is

proposed to installed Moving Bed Biofilm Reactor (MBBR) type sewage treatment plant of 100 KLD of

capacities. There will not be any incremental pollution load on nearby surface water bodies due to

proposed project.

Process Description: Design of STP Approximately 882 kl per day sewage/waste water will be generated from the proposed project. All

quantum of generated sewage will be treated in well-designed in-house sewage treatment plant. After

meeting stipulated standards, treated waste water will be utilized for flushing purpose and horticulture

purpose.



Details of Sewage Treatment Process: The plant consists of the following units: • Bar Screen • Equalization tank • MBBR Tank • Secondary Settling Tank • Pre Filtration Tank • Pressure Sand Filter • Activated Carbon Filter • Final Collection Tank • Sludge Collection Tank • Filter Press • Blower and Auxiliary Units

Figure 3: Schematic Diagram of MBBR Based STP

The sewage 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 will be supplied to meet the oxygen requirements by means of blower and fine bubbles

air diffusers. In MBBR reactor, thousands of polyethylene biofilm carriers operate 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. After MBBR reactor, sewage will

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

gravity. There will be provision for sludge recirculation, if needed. This settled sludge may be recycled

through sludge pump to MBBR reactor to meet the mixed liquor suspended solids (MLSS) requirement.

Excess sludge will be discharged through a filter press where solid and liquid will be separated. The

sludge collected with has low moisture and after drying can be used as manure. The collected liquid will

be re-circulating through the system. Final discharge of treated 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 Ultraviolet (UV) disinfection system. Treated sewage will meet the norms prescribed by

Environmental (Protection) Rules,1986, Schedule VI for Discharge to Inland Surface Water but will be

utilized for flushing and horticulture.

Design Parameters



Design parameters for proposed STP are given below:

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., 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 bio

carriers 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.



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. 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, Odorless and will be reused for plant units and horticulture purpose.

Ultraviolet (UV) Disinfection System (Optional)

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. UV light source is mounted so that water 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



Sewer System

The alignment and slope of the sewer line will follow the road network, drains or natural ground surface

and will be connected to the trunk sewers. The discharge point will be a treatment plant, a pumping

station, a water course or an intercepting sewer. Pumping stations would be provided at places where the

natural slope of the terrain is insufficient to permit gravity flow or the cost of excavation is

uneconomical to do the same.

9 RAIN WATER HARVESTING

The storm water collection system for both premises shall be self-sufficient to avoid any stagnation of

rain water. The amount of storm water run-off depends upon many factors such as intensity and duration

of precipitation, etc. The drains shall be located near the carriage way along either side of the roads.

Taking the advantage of road camber, the rainfall run off from roads shall flow towards the drains.

Storm water from various buildings of both parts of project will be connected to adjacent drain by a pipe

through catch basins. Therefore, it is proposed to provide total 05 rainwater harvesting pits at selected

locations within both parts of the project, which will catch the entire run-off.

1) Since the existing topography is congenial to surface disposal, a network of storm water pipe

drains is planned adjacent to roads. All building roof water will be brought down through rain

water pipes.

2) Proposed storm water system consists of pipe drain, catch basins and seepage pits at regular

intervals for rain water harvesting and ground water recharging.

3) For basement parking, the rainwater from ramps will be collected in basement storm water

storage tank. This water will be pumped out to the nearest external storm water drain.

4) Peak Hourly rainfall of 50 mm/hr shall be considered for designing the storm water drainage

system.

Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak hourly

rainfall has been considered as 50 mm/hr. The recharge pit of size 1.5 m x 1.5 m x 2.5 m depth is

proposed harvesting the rain water. Inside the recharge pit, a recharge bore is constructed having

adequate diameter with PVC slotted pipe up to a layer where sandy aquifers/ deeper aquifer permeable

layers exist. The bottom of the recharge structure will be kept 5 m above the confined aquifer level. At

the bottom of recharge well, a filter media is provided to avoid choking of the recharge bore. Design

specifications of the rain water harvesting plan are as follows:

• Catchments/roofs would be accessible for regular cleaning.



• The roof will have smooth, hard and dense surface which is less likely to be damaged allowing

release of material into the water. Roof painting has been avoided since most paints contain toxic

substances and may peel off.

• All gutter ends will be fitted with a wire mesh screen and a first flush device would be installed.

Most of the debris carried by the water from the rooftop like leaves, plastic bags and paper

pieces will get arrested by the mesh at the terrace outlet and to prevent contamination by

ensuring that the runoff from the first 10-20 minutes of rainfall is flushed off.

• No sewage or wastewater would be admitted into the system.

• No wastewater from areas likely to have oil, grease, or other pollutants has been connected to the

system.

Calculations for storm water load

Roof-top area = Ground Coverage = 16,434.38 m2

Runoff Load

Roof-top Area = 16434.38 × 0.050 × 0.85

= 698.46 m3 /hr

Total Runoff Load = 698.46m3/hr

Taking 15 minutes Retention Time, Total volume of storm water = 698.46/4

= 174.615 m3 Taking the effective diameter and depth of a recharge pit as 3m and 2.5 m respectively, volume of a single recharge pit = 3.14 x 1.5 x 1.5 x 2.5 =17.66 Hence, No. of pits required =174.615/17.66 = 9.88or say 10 Pits. 10 Rain Water Harvesting pits are proposed for artificial ground water recharge from roof top.

Figure 5: Solid Waste Management Scheme (Construction Phase)

During the operation phase, solid waste will comprise domestic as well as agricultural waste. The solid

waste generated from the project will be mainly domestic waste and estimated quantity of the waste

shall be approx. 6151kg per day (@ 0.50 kg per capita per day for all kind of dweller, @ 0.15 kg per

capita per day for any kind of visitor, @ 0.25 kg per capita per day for the staff/Student/Teacher and



landscape wastes @ 0.02 kg/acre/day. Following arrangements will be made at the site in accordance to

Solid Wastes Management Rules, 2016.

Collection and Segregation of Waste

1. House to house collection system will be provided for collection of domestic waste in colored

bins.

2. Local vendors will be hired for waste collection and segregation.

3. Adequate number of colored bins (Green and Blue & dark grey bins– separate for Bio-

degradable and Non Bio-degradable) will be provided at strategic locations.

4. Litter bin will also be provided in open areas.

Treatment of waste

• Bio-Degradable waste

1. Bio-degradable waste will be subjected to composting through Organic Waste Convertor and the

compost will be used as manure.

2. STP sludge is proposed to be used in horticulture area.

3. Horticultural Waste will be used as manure.

• Recyclable waste



i. Grass Recycling: The cropped grass will be spread on the green area. It will act as manure after

decomposition.

ii. Recyclable waste like paper, plastic, metals, etc. will be disposed through local recyclers.

Disposal

A local vendor will be hired for disposal of solid waste during operation phase. Solid waste

management Scheme is depicted in the following figure:

13. GREEN AREA

Total green area measures(Existing + Expansion) 7448.03 m2 i.e. 10% of the net total plot area which

will be area under landscaping. Evergreen, native species will preferably be planted at the project site.

Native species are adapted to natural conditions and also requires less aftercare and maintenance. Trees

with large & round canopy will be planted. Plantation will act as noise buffer and will provide surface

for dust settlement. Green belt development plan for the area is given below

Green Belt development Plan



All the developments are associated with the pollution of one or more environmental component. Plants

are the natural sink of that pollution. Plants help in abatement of the pollution and restore the degraded

environment. Green belt lowers down the air pollution by providing a surface to settle down or by

absorbing the pollutants, attenuate noise level and uses the waste water. Phyto-remediation is one of the

most successful available technologies of restoring the degraded environment. For this project area of

7448.03 m2 is proposed to be put under green cover. Green cover will comprise of:

• A peripheral green belt

• Avenue plantation

• Lawns/parks & grass cretes

• Planters

Selection of Plant Species for Green Belt Development

Selection of plant species for the development depends on various factors such as climate, elevation and

soil. The plants having following desirable characteristics would be selected for plantation

1. Species should be fast growing and providing optimum penetrability with minimal maintenance.

Perennial, evergreen & fast growing trees

2. Species should be wind-firm and deep rooted

3. Indigenous and locally available species

4. Plants with high foliage density, leaves with larger leaf area and hairy on both the surfaces.

Round, thick & spreading canopy is preferred for peripheral green belt and oblong canopy for

road side plantation

5. Ability to withstand conditions like inundation and drought

6. Soil improving plants (Nitrogen fixing rapidly decomposable leaf litter)

7. Bird and insect attracting species

8. Tolerant to climatic conditions of the area and with less water requirement. Species tolerance to

air pollutants like SO2 and NO2 should be preferred

9. Plants with ornamental foliage & shrubs with fragrant flowers and fruit bearing

10. Plantation should maintain ecological & hydrological balance of the region.
