Collection of sewage from existing UGD:

Small inlet chamber of 1 M X 0.7 M X 0.6 M was constructed, to trap the sewage

before it enters the exis�ng sep�c tank .From that point sewage is fed through

coarse bar screen to collec�on Sump.

Solution

Treatment Methodology AdoptedA�er detailed study of the exis�ng site condi�ons we have proposed AWT Technologies, Canada, Advanced SBR technology.

Advanced SBR technology is being widely used all over the world and well proven both in India and abroad. AWT's Advanced

SBR system treats every batch of influent in a Sequencing manner con�nuously with following advantages:

Collec�on Sump (Under Ground)A collec�on sump is constructed with 9M DIA and 3.5 M depth and the inlet sewage is let in through a coarse bar screen to block

derbies and solid floa�ng ma�er. To avoid sep�city of incoming sewage, 2 No's of 7.5 HP each Aspirator type of mixers are

provided on float mount assembly with rail mechanism to address the level fluctua�ons in the tank .

Less Foot print

Low total power required to run the plant

Ability to fully automate the plant

Less Maintenance and associated breakdown �mes

Op�on of Process or Diffused Aera�on

Be�er in removal of Nitrogen & Phosphorous Principal of Opera�on o f Advanced Sequen�al Batch Reactor (ASBR).

Pretreatment Units -Manual Screen , Oil & Grease Trap , Grit Chamber (Above Ground)

From the collec�on sump the Sewage is pumped to the

collec�on tank and the bar screen, Oil trap and Grit removal

chambers (4 x 1.5 x 1 M) and enters into distribu�on chamber.

AWT's Advanced SBR system treats every batch of influent in a

Sequencing manner con�nuously with following advantages:

The Triton Process aera�on system Make: Aera�on Industries Inc , USA capable of higher oxygen transfer efficiency with good

horizontal mixing is provided in the ASBR tank on easily retrievable float moun�ng and rail mechanism to address the fluctua�ons in

the water level of ASBR tank . The system provided is having following merits over conven�onal aera�on systems.

The ASBR u�lizes a simple repeated �me-based sequence of opera�on, which incorporates:

Comple�on of these three opera�ons in the sequence described above cons�tutes a cycle, which is then repeated.

FILL – AERATION (for biological reac�ons)SETTLING (for solids-liquid separa�on)DECANTING (to remove treated effluent)

EPA-defined "Fine Bubble" Aera�on, less than 2.2mm in size

O2 Transfer efficiency (1.83kg/KWH) from 5 HP to 75 HP and superior Mixing (1�/Sec) from

1.8 m to 10m deep.

Negligible noise levels - Only 60 Decibels

No VFD'S Requirement – Individual Turn down Capability.

Low speed (750 RPM) opera�on ensures extended aerator life.

No membranes are used in the systems, so no Choking or se�ling Issues.

No gearbox, aerosols, splashing, or released pathogens into the air and eliminates odors.

Decan�ng Mechanism :

Control Room and Control Panel:

Result

Electrically actuated variable speed moving weir decanters is provided in

ASBR tank , the decan�ng mechanism , control mechanism with PLC has

been supplied by AWT Technologies , Canada.

Control and electrical panel is provided to control all the

electromechanical items such as pumps, decanter, aerators and mixers.

The same is incorporated in panel room specifically constructed for the

purpose.

The performance of the STP plant is very good , the quality of treated water

ecxceed the design parameters and the treated water is successfully used

for secondary uses like

The decanter func�ons under a controlled (but variable) constant lowering rate. During aera�on and se�lement, the decanter collec�on weir will be situated (parked) above the top water level of the reactor. The decanter will automa�cally operate as a high level overflow in the event of an emergency. The drive mechanism is designed for a con�nuous duty, variable speed mode of opera�on thereby producing a uniform flow rate un�l the decanter weir reaches BWL at the end of the decanter phase, thereby maximizing se�ling �me.

The management of APGENCO

is very happy with the overall performance.
