1. Pump pit•

Collecting wastewater from brewery pump togroup tanks for treatment.

2. Coarse Screen•

To remove debris, floating material, large
particles from the wastewater before it enters

the influent pump pit.
•Total Volume: 87.5 m3•Working Volume: 53.0 m3•

Peak Flow: 150 - 200 m3/h

2- Equalization Tank•
Balance influent water from other area.

3- Coarse Screen•
To remove small particles from the wastewater
before it enters the Equalization Tank.
••

Total Volume
Working Volume: 1124 m3: 1034 m3

4- Calamity Tank•

Store and balance influent when there is out of
spec and pumped back to Equalization tank.

5- Intermediate Tank•

Balancing water before feeding to UASB tank,Reserve water to run circulation in case nowastewater.

•Working Volume : 44 m3

6- UASB / Anaerobic Tank•

Wastewater from Influent pump pit passthrough anaerobic blanket sludge andconvert the biodegradable organic matter inwastewater into biogas. Then will betransported to E.Q tank to treat.

•Biogas will recover and send to Biomass boiler•

Working Volume : 1044 m3
