9.0 Process description:

MBBR Technology

The sewage generated from the various sources will be collected in the collection

tank through the bar screen chamber in order to remove the floating materials and

particle size greater than 15mm. The Screened sewage is then led to the aeration

tank.

In the aeration tank, air is diffused through special type of diffusers to oxidize the

organic matters with the help of air blower & diffuser arrangement. Biological

treatment takes place through MBBR media. Then the overflow from aeration tank

is sent to the Clarifier tank for settling. The bioflocs formed in the aeration tank will

be settled at the bottom of the Clarifier tank through Clarifier rake mechanism and

the settled sludge will be pumped to the sludge holding tank through the return

sludge pump. From sludge holding tank, the sludge will be fed to filter press unit

for dewatering purpose through screw pumps.

The clarified overflow will be collected in the Clarified water tank from where it is

pumped to the Pressure Sand Filter, Activated Carbon Filter through Filter feed

pump for the removal of suspended solids, organic matter and odour. The filtered

water is stored in the filtered water tank / UF feed tank.

The filtered water will then be fed to the UF unit through UF feed pump. UF

permeate water will be used for flushing & gardening. UF backwash & cleaning are

done at regular intervals in order to prevent the membranes from chocking and

scaling of the membrane.

Assume O2 requirement = 2 kg of O2/ 1 kg of BOD

1kg of BOD / 2 kg of O2

Assume BOD for sewage = 400 mg/l = 0.40 kg/m3

BOD Load = 400 x 0.40

= 160 kg of BOD/day

O2 requirement = 160 x 2

= 320 kg of O2/day

Oxygen transfer @ 16% of SOTR = 320 / (0.16 x 0.23x 0.65 x 0.95)

= 320 / 0.023 = 13913.04



18

α = 0.65; β = 0.95

Density = 1.16 => 13913.04 / 1.16 = 11994 m3/day

Air requirement = 11994 / 24 = 499.75 m3/hr

Therefore 500 m3/hr (1 + 1) each for aeration tank, the air flow rate is adequate.

No. of diffusers provided = 50 no

Assume O2 requirement = 2 kg of O2/ 1 kg of BOD

1kg of BOD / 2 kg of O2

Assume BOD for sewage = 400 mg/l = 0.40 kg/m3

BOD Load = 207 x 0.40

= 82.8 kg of BOD/day

O2 requirement = 82.8 x 2

= 165.6 kg of O2/day

Oxygen transfer @ 16% of SOTR = 165.6 / (0.16 x 0.23x 0.65 x 0.95)

= 165.6 / 0.023 = 7200



17

α = 0.65; β = 0.95

Density = 1.16 => 7200 / 1.16 = 6206.9 m3/day

Air requirement = 6206.9 / 24 = 258.62 m3/hr

Therefore 300 m3/hr (1 + 1) each for aeration tank, the air flow rate is adequate.

Coarse Bubble Diffuser Data1 Quantity 8 No2 Type Tubular Coarse bubble3 Diameter 90 mm Dia4 Length 1000 mm5 MOC EPDM6 Location Collection tank7 Make HECS

Fine Bubble Diffuser Data8 Quantity 22 No9 Type Tubular Fine bubble

10 Diameter 90 mm Dia11 Length 1000 mm12 MOC EPDM13 Location Aeration tank14 Make HECS

Adequacy calculation:

Blower capacity = 300 cum/hr

Air flow rate per diffuser = 10 m3/hr

Therefore no. of diffusers required = 300 / 10 = 30 nos

No. of diffusers provided = 30 nos

Hence it’s adequate.
