STP design details

Sewer System:

The spent water in the project is proposed to be collected using a network of sanitary pipes.

The sanitary piping will be based on the two pipe stack system. The two pipe stack system

comprises of a stack dedicated for soil water and the other for sullage (gray water) collected

from bath, wash basins, kitchen sink and utility sinks.

The soil and waste stacks are laid in the ducts and the waste stack connects to a gully trap

and farther connects to an inspection chamber / manhole. The soil stack directly connected

to an inspection chamber / manhole. The stacks extend till terrace.

The network of inspection chamber / manhole is designed as per NBC to flow 1/2rd or 2/3rd

full as a gravity sewer. The gravity sewer is terminated into a STP for further treatment &

reuse for secondary purposes.

250 KLD SEWAGE TREATMENT PLANT

Design of the individual units:

Bar Screen Chamber:

Provide a chamber of size 1.0 m x 0.65 m to suit sewer gradient to accommodate an inclined

bar screen with opening less than 10 mm. Provide a bar screen of 20 X 6 mm flats with 10mm

spacing in between.

Design Criteria:

Velocity through screen : 0.8 m/Sec.

Discharge : Discharge / day /8

=2,50,000/8

=8.6x10-3 Cum. /sec

Peak Load : 3 times the discharge

=8.6x10-3 x3.0

=0.0258 m3 /sec

Adopting screens with bars of 10 mm width and 20 mm clear opening considering 1.2 times

the net area of opening,

Net Area = 0.0258 /0.80 =0.0322 m2

Gross area = 1.2 times of the net area of opening

= 1.2 X 0.0322 =0.0386 m2

Assuming the inclination of screen of 60° to horizontal. Gross area of screen needed would

be 1.0X0.45 Mt. for ease of maintenance.

Equalization tank:

The flow from the bar screen chamber is let into the equalization tank of minimum 8 hours

capacity. This tank is provided to even out the flow variation, and to provide a continuous

feed into the secondary biological treatment units.

Design flow = 2,50,000Lt/day

Provide min 8 hours holding capacity.

Hence required volume of the tank = 83.33m3

Provide a tank of 85,000 Lt. Capacity.

The tank size would be 7.5X4.5X2.5 m SWD (effective volume)

Sequential Batch Reactor (SBR) tank

Biological stabilization of the wastewater is accomplished in the SBR tank in the presence of

microorganisms, for the respiration of which oxygen is supplied by means of diffused aeration

comprising of membrane diffusers and air blowers. As micronutrients such as nitrogen and

phosphorus will be already present in sufficient quantities, no external supplementation will

be necessary.

The aeration tank is provided with diffused aeration system to supply the air for the

microorganism’s growth. The nutrients required for the microorganism’s growth are organic

matter, which is present in the domestic effluent.

The MLSS level is maintained in this process to enhance the aeration process. Optimum

concentration of MLSS to be maintained is in the range of 3500 – 4500 mg / lit. During the

aeration, the sludge starts to settle in this tank. At that time, the blower will be off.

Here the settling of the solids takes place and the clear water from the top is pumped to the

clear water tank.

Design flow = 2,50,000 Lt/day

Considering the 3 batches

Volume of the tank = 250 / (3 batches x 3 reactors x 0.5 decanting ratio)

= 250 / (3 x 3 x0.5)

Hence required volume of the tank = 55.55 cum/ reactor

Provide a tank of 56 cum/ reactor capacity

The sizes of the tank will be 6.0X3.8X2.5 m

Flow Quantity 250 cum/day

BOD In 300mg/l

Tank Volume 3 x 56cum

Diffusers Fine Pore Diffusers

Food X Microbe 0.12

MLSS 4000mg/l

No. of tanks 3 Nos.

Air Blowers

Sewage inflow/batch = 250/9 = 27.77 cum.

Total BOD5 load = 250 mg/l.

BOD load in tank in Kg = (250x27.77) / 1000 = 6.94 kg/batch

For 1 kg of BOD removed 1.2kg of oxygen is required

Density of air = 1.17

% of oxygen in air = 21% = 0.21

Alpha factor = 0.65

Beta factor = 0.90

Oxygen transfer efficiency = 0.12

There for Air required = 6.94 x 1.2 / ( 1.17 x 0.21 x 0.65 x 0.9 x 0.12)

= 8.32 / 0.017

= 489.41 cum/ batch

Aeration time = 4hr

There for air required in cum/ hr = 122.35 cum/ hr = 72.01cfm.

Consider 35% excess considering the air required in the equalization tank

Total air required = 97.21cfm

Hence provide 2 blowers of 100cfm

One as standby with an operating pressure of 0.5KSC.

Transfer rate of oxygen in 1m.

Long membrane diffusers = 10 cum/ hr

There for total number of membranes required = 97.21/10 = 10 nos

Clarified Water Tank – 1 NO:

The settled water from the settling tank is expected to meet the standards with respect to

BOD and TSS for discharge to island surface waters. However, it is our intention to improve

the quality of effluent further in order to make it fit for reuse. For this reason, further

secondary treatment in the form of coagulation, filtration and disinfection is proposed. The

clear water from the settling tank shall be fed to the clarified water tank, from where it will

be pumped to the filters.

Design flow = 2,50,000Lt/day

Provide min of 16 hours holding capacity.

Hence required volume of the tank = 166.66 m3

Provide a tank of 1,67,000 Lt. Capacity

The sizes of the tank will be 9.0X7.5X2.5 m

Pressure Sand Filter:

Flow = 2, 50,000Lt/day

Loading rate = 15 cum/ Sqm/hr

Considering the operation of 20 hours of filter

Provide a Pressure Sand filter of 1030mm say 1200 mm dia with sand as media over layer,

under drain pipe, laterals face piping etc.,

Activated Carbon Filter:

Flow = 2, 50,000 Lt/day

Loading rate = 15 Cum/Sqm/hr.

Considering the operation of 20 hours of filter

Provide a pressure sand filter of 1200-mm diameter with activated carbon filter media with

under drainpipe, lateral face piping.

Chlorination:

The filtered water is further chlorinated through an online automatic chlorination

system with electronic dosing pump for disaffection. Provide one no. 100 Lts capacity

automatic Chlorinator with electronic metering pump to ensure the residual chlorine level to

be less than 2 PPM for disinfect ion so that it will not effect the plantations. The Chlorinator

Duty: To pump the Treated effluent from the Pre-filtration tank through the Pressure Sand

Filter and Activated Carbon Filter.

Sludge Disposal:

The biomass in the aeration tank stabilizes BOD in wastewater by consuming the organic

matter in the wastewater. The metabolic activity results in growth of the biomass population

in the aeration tank. Consequently, in order to contain the level of MLSS in the aeration tank

to the design level of 4000mg/l, it will be necessary to bleed off or waste the excess

activated sludge. For this purpose, a sludge-holding tank of 20 cum with air supply and one

no. filter press is proposed.

Capacity 20.0 cum/day

Sludge Volume Index 100-150mg/l

Filter Press:

The present invention relates to a method and apparatus for treating the sludge is generally

known as "reburning", lime sludge in order to regenerate the sludge, which in a flash dryer

making method has been separated in connection with a causticizing process, to form active

lime.

CONCLUSIONS:

The sewage treatment plant is designed based on the proven activated sludge process with

extended aeration technology. The STP would be able to treat the sewage to the standards

prescribed by the local PCB with treated BOD5 levels less than 30 Mg/lit. The treated water

can be used for the tertiary uses like gardening, car washing, floor washing, toilet flushing,

ground water recharge etc. The treated water is safe to come in contact as the chlorination

is done to kill the bacterial (disinfection).

4.2 Preventive Measures against Specific Hazards

a) Fall prevention at the workplace:

� All open sides of building from which a worker might fall and openings into which a

worker might fall will be adequately covered or barricaded.

� Where barricades could not be installed, safety nets will be installed close to the level

at which there is danger of falls.

� Where secure foothold is impracticable, safety belts or harnesses with secure

anchorage points will be provided.

� At elevated places such as encountered in formwork construction for beams, secure

access and foothold will be provided.

b) Falling Material Hazards Prevention and Protection:

� Falling material hazards will be prevented by means of overhead screens and

hoardings.

� Discarding of waste materials by throwing down the side of the building will be

prohibited. The provision of refuse chutes for discarding small items and the use of

lifting equipment to remove large ones will be clearly communicated and enforced.

The use of c1eaning teams working after work hours will be reduce potential hazards.

� Where there is danger of collapse of structures steps will be taken to barricade off a

safety zone until repairs are made.

c) Structural Failure Prevention

� All structures will be properly designed.

� Temporary structures such as formwork and its supports will be properly braced in all

directions to prevent displacement.

� Vibrating machinery, piping or other parts will not be brought in contact with

structures unless they are specially designed for it.

� Formwork support will not be removed until the concrete it supports has attained its

required strength.

� Structures will be designed by competent engineers and be put up under the

supervision of experienced supervisors.

� They will be inspection before use by a competent engineer and thereafter respected

on a regular bas or where parts are dam aged and repaired.

� Ensured only materials are adequate strength be used

d) Refuse Disposal :

� Refuse accumulative will never be allowed as the resulting loading may be excessive.

� Discharge of waste concrete on platforms accumulating bricks on work platforms could

re-suit in a sudden collapse and will be avoided.

� Refuse will be removed daily to prevent accumulation. Materials liable to cause

persons to slip or trip and fall will be cleared immediately.

� Properly designed refuse chutes will be constructed and used. Throwing refuse over

sides of buildings will be prohibited.

� Refuse removal teams working after work hours will be organised where normal

cleaning cannot cope with the build up of waste materials.

� Projecting nails will be removed or bent over.

e) Noise:

� Equipment and processes generating loud noises will be avoided as far as practicable.

Air compressors and generators, for example, will be located away from the

concentration of workers.

f) Fire Protection

� At every level of construction where combustible materials are liable to be used or

stored, a 9 kg dry ABC powder extinguisher will be provided. Where the travel distance

exceeds 30 m additional ones will be provided. 2.5 kg BCF extinguishers will be placed

near switch boards.

� There will be trained personnel available on the site at all times. All workers at the

site will be trained to operate the extinguisher.

� The fire alarm procedure and the evacuation sequence will be clearly spelled out and

the workforce notified. In workplaces where fire hazards are potentially more

hazardous (e.g. in underground tunnelling work), drills will be carried out.

� Combustible and flammable materials will be stored away from the source of heat

such as generators, welding sets and electrical distribution boxes.
