AEROBIC DIGESTER DESIGN PARAMETERS
Sludge Flowrate to the Digester
Inlet Sludge Concentration
Solids Loading to the Digester
Inlet Volatile Solids Fraction
= 7,928.7 gal/day
= 1.00%
= 661.3 lb/day
AEROBIC DIGESTER BASIN DESIGN VALUES
No./Basin Geometry:
= 2 Rectangular Basin(s)
= (30.0 m³/day)
= (300.0 kg/day)
= 76.2%
Length of Basin:
= 20.8 ft
= (6.3 m)
Width of Basin:
= 21.4 ft
= (6.5 m)
Min. Water Depth:
= (4.5 m)
= 14.7 ft
Min. Basin Vol. Basin:
= 49,060.0 gal
= (185.7 m³)
Max. Water Depth:
= 21 ft
= (6.4 m)
Max. Basin Vol. Basin:
= 70,085.7 gal
= (265.3 m³)
AEROBIC DIGESTER PROCESS DESIGN PARAMETERS
= 35.4 days
= 18 C
= 40%
= 2%
= 2.00 lbs O2 per lb VSS Destroyed
= 100.0%
= 403.2 lb/day
= (182.9 kg/day)
= 65.8%
= 459.6 lb/day
= (208.5 kg/day)
= 2,755.7 gal/day
= (10.43 m³/day)
= 21,025.7 gal/basin
= (79.59 m³/basin)
Solids Retention Time:
Digester Design Temperature:
Volatile Solids Destruction:
Digester Solids Concentration:
Oxygen Supplied for Digestion:
Oxygen Distribution Per Basin:
Actual Oxygen Required:
Volatile Percentage After Digestion:
Estimated Dry Solids to be Removed:
Volume of Solids to be Removed:
Estimated Supernatant Volume:
Assumed Supernatant Duration:
= 180 minutes
Calculated Supernatant Flow:
= 116.8 gpm
= (7.4 l/sec)
The Volatile Solids Destruction listed above shall be used for determination of the oxygen demand during summer conditions.
It should be noted that the actual VSS destruction will be dependant upon digester inlet condition, temperature, and operating
conditions.
The Digester Solids Concentration is reflected as an average concentration, assuming the operations include frequent settling
and supernating practices.

AEROBIC DIGESTER EQUIPMENT CRITERIA
SCFM Required for O2 Demand:
= 188/basin
= (319 m³/hr/basin)
SCFM Required to Mix:
= 284 SCFM/basin
= (482 Nm³/hr/basin)
Max. Discharge Pressure:
= 9.67 PSIG
= (66.70 KPA)
Avg. Power Required:
= 438.72 kW-hr/day
