1. INTRODUCTION

The Sewage Treatment Plant (STP) is designed for the treatment of soil and waste water of

Phase- 1 and Phase-2.The internal soil and waste water from toilets and kitchens shall be

collected by the two pipe system and conveyed to STP through the external sewerage piping

system. The proposed plant could treat 1000,000 liters of sewage waste water in a day. The

treated water can be reused for land irrigation, gardening, toilet flushing and vehicle washing

etc.

PROCESS DECRIPTION

To have eco-friendly & natural treatment, this plant is designed based on the

biological treatment concept. This means naturally occurring microbes (which are

present in sewage water itself) removes or degrade the organic matter present in

the sewage & at the end clean water is available for the non potable usage or to

dispose safely in the drainage or river bodies as per the norms.

1. Pre – Treatment:

Screening : This is the first units of the plant in which large or floating

materials in the sewage gets arrested and blockage or choking of the downstream

equipments can be avoided. This arrested material will be removed manually and

then will be disposed off suitably

Oil & Grease trap : Domestic sewage sometimes gets waste water from

pantries or kitchen which contains free oil. This oil if not removed then creates the

problem of scum accumulation and affects the functioning of microbes.

To avoid this, oil & Grease trap is provided after the bar screen, where free floating

oil is arrested prior to entry in the plant. Accumulated oil will be removed

periodically and disposed off properly.

Equalization : To absorb variation in quantity and quality of sewage and to

provide uniform flow at the downstream treatment process, a collection or

equalization tank is provided. This will avoid shock loading and process upsets of

the treatment plant. To avoid settling of suspended solids in this tank, continues

air agitation is provided.

If at site, septic tank is provided then collection tank as well as air agitation is not

required.

2. Secondary Treatment:

Biological Treatment : This is the main section of the plant where degradation

of organic pollutants with the help of aerobic micro-organism takes place. To

provide higher surface area for micro-organism, floating media is provided. On

which micro-organism growth takes place. This makes bioreactor is of hybrid

concept in which both suspended growth as well as attached growth principal for

micro-organism is achieved. Due to higher population of micro-organism, effective

volume of bioreactor reduced drastically as compared to conventional aeration

tanks.

To maintain the aerobic condition in the bioreactor, air supply arrangement is

provided by means of aeration equipment which has high oxygen transfer

efficiency.

Tube Settler : Gravity overflow from the bioreactor is collected in the tube

settler tank. In this settling tank, generated sludge from the bioreactor undergoes

a gravity settling. Clear supernatant from settling tank will flow by gravity to a

chlorine contact tank.

To reduce the plan area of settling tank, tube modules are placed in this tank to

increase the settling area of the tank. Since this tank is a hopper bottom tank due

to which there is no need of sludge scrapping mechanisms.

Disinfection : Supernatant from Tube settler, flow by gravity to the chlorine

contact tank. To disinfect the harmful bacteria in the treated water as well as to

remove the refractory organics from treated water, in this tank hypo chlorite

solution is dosed with the help of dosing system.

Sludge disposal system : Settled sludge from tube settler will be removed

by pumping to the sludge holding tank. The sludge from the sludge holding tank will be

pumped to filte press to make the dry sludge cakes and will be collected in the bags for further

reuse to gardenning.

3. Tertiary treatment:

Secondary treated water from chlorine contact

tank will be further passed through sand media filter followed by activated carbon

filter.

Filtered water will be collected in the Treated water Storage tank from where it will

be for desired non potable application. Backwashed water from filters will return

back to equalization tank.

By doing effective treatment and operation of plant will give

enormous benefits such as

- It will avoid the water pollution.

- It will help us to give hygienic surrounding. - After required treatment, treated water can reduce the 60-70 % fresh water

requirement, and to be used for toilet flushing, gardening, construction etc. Thus it can save a lot on water expenditure as well as provide a remedy on present water crises.

- Being a water recycling & conservation system, commercial establishment gets depreciation benefits for promoting green & eco-friendly development.

Above all, it will be ensuring safe & hygienic environment to our society.

DESIGN CALCULATIONS

1. BAR SCREEN CHAMBER–

Flow – 1000 m3/day

Average Flow for 22 hrs operation– 45.45 m3/hr

Retention Time for Bar screen = 2 to 4 min

Required Tank Volume = 2 m3

Now, considering Retention Time = 2.88 min (0.048 hr)

Therefore, Tank Volume = 45.45 × 0.048 = 2.18 m3

Considered Volume of Tank – 2 m3

Let SWD of Tank – 0.5 m

Area of Chamber – 2/0.5 = 4 m2

Consider Length of Tank –2.7 m

Therefore Width of Tank = 1.5 m

Therefore Tank Size is 2.7 m × 1.5 m × 0.5 m SWD + 1.5 m FB - 1 No.

2. O & G CHAMBER –


Average flow– 45.45 m3/hr


Retention Time for O&G Chamber = 15 to 20 min for Domestic Sewage

Required Tank Volume = 2 m3 Now, considering Retention Time – 17.4 min (0.29 hr)

Therefore, Tank Volume = 41.66 × 0.29 = 12 m3


Let SWD of Tank – 1 m

Area of Chamber – 12/1= 12 m2

Consider Length of Tank – 8 m


Therefore Tank Size is 8 m × 1.5 m × 1 m SWD + 1.9 m FB – 1 No.

3. COLLECTION CUM EQUALIZATION TANK –

Flow – 45.45 m3/hr

Retention Time for Collection Tank = minimum 8 hrs

Therefore, Tank Volume = 45.45 × 8.0 = 363.60 m3


Let SWD of Tank – 2 m

Area of Chamber –370/2 = 185 m2

Consider Length of Tank – 13.9 m


Therefore Tank Size is 13.9 m × 13.6 m × 2 m SWD + 2 m FB – 1 No.

4. AERATION TANK –

Flow – 45.45 m3/hr

BOD Load In aeration Tank – (350-20) = 330 mg/lit

Expected BOD Reduction– 95 %

BOD to be reduced = 350 X 95% = 332.5 mg/lit

MLSS – 4000 mg/lit

F/M – 0.28

For MBBR Technology Retention Time required = 6-7 hrs

Therefore, Tank Volume = 45.45 × 7.0= 318.15 m3

Considered volume of tank – 320 m3

Considering 2 No. of Aeration tanks ie. 160 m3 X 2 Nos.


Let the SWD – 3.5 m

Area of Tank – 160/3.5 = 45.70 m2

Width Considered – 6.4 m

Length – 7.20 m

Therefore Aeration Tank Size 7.20 m × 6.4 m × 3.5 m SWD + 0.3 M FB

– 2 Nos.

As per standard practice, MBBR Media should be 20% of Aeration

Tanks Volume

= 300 X 20% = 60 m3

Therefore, MBBR media require will be 60 m3 in aeration tanks ie. 30 m3

in each aeration tank.

5. AIR BLOWER –

BOD Load In aeration Tank – (350-20 )=330 mg/lit

BOD Load = 1000 × 330/1000

= 330 kg/day

Air Requirement for BOD Reduction:

1 kg of BOD required 1-1.5 kg of Oxygen, considering 1.2 kg of Oxygen. Therefore, 330 kg BOD required 330 Kg BOD X 1.2 kg O2

1 kg of BOD

Hence, Theoretical oxygen requirement per day = 396 kg/day of O2

Therefore theoretical oxygen requirement per hour = 396/24

= 16.5 kg/hr

Standard oxygen requirement = Theoretical oxygen requirement

AlphaX[BetaXCsW-DO]XTheta^(Tww-200C)

Css

Where,

Alpha = 0.5

Beta = 0.95

Theta = 1.024

Waste water temperature, Tww = 270C

DO maintained for designed flow = 2 mg/lit


Surface saturation C = 7.97

Site basin saturation Csw = 9.26

Standard basin saturation Css = 10.57

Therefore,

Standard oxygen requirement = 16.5

((0.5X (0.95X9.26-2)/10.57) X (1.024^(27-20)))

= 42.8 kg of O2/hr

Total air requirement = Actual O2 requirement

Density of air X% of O2 in air by weight X sote%

Where,

Density of air = 1.2 kg/m3

Considering, SOTE % per Mtr SWD of Aeration tank – 6 % per Mtr

Sote = Standard oxygen transfer efficiency = 21% (calculated)

% of O2 in air by weight = 0.2306

Therefore,

Total air requirement for Aeration Tanks = Actual O2 requirement

1.2 X 0.2306 X 0.21

= 42.8

1.2 X 0.2306 X 0.21

= 736.5 m3/hr

Now, considering 30 % of air require for equalization tank, intermediate tank,

Sludge Holding Tank & treated water tank.

Therefore Total air requirement will be = 736.5 X 30 % = 220.95 m3/hr

Therefore air blower capacity = 736.5 + 220.95

= 957.45 m3/hr

Therefore take air blower of 1000 m3/hr capacity @ 0.4 kg/cm2.

i.e. 2 No. of Working Blowers having capacity of 500 m3/hr


6. DIFFUSER MEMBRANES FOR AERATION TANK –

Consider size of diffuser membranes as 90 mm OD X 1000 mm length

Considering average 736.5 m3/hr air required for Aeration tank

Number of diffusers = (Air to be supplied to aeration tank) / (minimum air flux

Rating)

= 736.5/7.5

= 98.2 Nos.

Therefore, number of diffusers will be 100 in aeration tank.

7. TUBE SETTLING TANK –

Flow – 45.45 m3/hr

Retention Time for Tube Settling Tank = 2.5 to 3 hrs

Now, considering Retention Time = 3.00 hr

Therefore, Total Tank Volume - 45.45 × 3.0 = 136.35 m3


Now, Consider 2 No. of Tube Settling tanks:

So, Volume of each Settling tank = 140 / 2 = 70 m3


Area of Tank – 70/3.3 = 21.3 m2

Width Considered – 3.2 m

Length – 6.7 m

Therefore Tank Size is 6.7 m × 3.2 m × 3.3 m SWD+ 0.3 FB – 2 No.

8. TUBE SETTLER MEDIA –

Flow – 45.45 m3/hr

Height of media – 0.55 m

Tube Media required for Each Tank = length X width X height of media

= 6.7 X 3.2 X 0.55 = 11.8 m3

Therefore, Tube media required for each Settling Tank will be 11.8 m3

Total Media required for 2 No. of Settling Tanks = 11.8 X 2 = 23.6 m3


9. CHLORINE CONTACT TANK/INTERMEDIATE STORAGE TANK –

Flow – 45.45 m3/hr

Retention Time for Chlorine Contact Tank = 2 to 3 hr


Therefore, Tank Volume - 45.45 × 3.0 = 136.35 m3



Area of Chamber – 140/3.1 = 45.16 m2

Consider Length of Tank = 14.2 m



10. PRESSURE SAND FILTER –

= 1319 kg

≈ 1300 kg


12. TREATED WATER TANK –

Flow – 45.45 m3/hr

Retention Time for Treated Water Tank = 5-7 hr


Therefore, Tank Volume = 45.45 × 7.0= 318.15 m3

Consider Length of Tank = 25.40 m Therefore Width of Tank = 3.6 m


13. SLUDGE HOLDING TANK –

BOD Load – (330 × 1000)/1000

= 330 kg/day

1 kg of BOD generates 0.25 kg of dry sludge per day.

1 Kg of BOD 0.2 kg of dry sludge

Hence, 330 kg BOD 66 kg of dry sludge

Considering 10 % slurry consistency

Therefore volume of 10 % slurry sludge = 66 X 100

10

= 660 liters

i.e. approximately 0.66 m3 per day

Considering Retention Time for Sludge Holding Tank = 5 months

= 150 days

Therefore, Tank Volume = 0.66 × 150 = 99 m3



Area of Chamber – 100/3.5 = 28.6 m2


Consider Length of Tank = 9.5 m



Filter Press: 24’’ X 24’’ X 20 Chambers is selected based on the dry sludge & Slurry generated.
