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.

Adequacy calculation
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

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.

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.

Hubert Enviro Care Systems (p)Ltd
( An ISO 9001 – 2000 Company )
M/S. Alliance Mall Developers, Coimbatore
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. UV dosing is
given for disinfection purpose. The filtered water is stored in the treated water tank
from where it is usde for gardening purpose.

Adequacy calculation
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

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.
