POST-SBR EQUALIZATION DESIGN PARAMETERS
Avg. Daily Flow (ADF): = 0.435 MGD
Max. Daily Flow (MDF): = 0.87 MGD
= (1,644 m³/day)
= (3,289 m³/day)
Decant Flow Rate from (Qd):
Decant Duration (Td):
Number Decants/Day:
Time Between Start of Decants:
= 1,813 gpm = (6.9 m³M)
= 60 min
= 8
= 180 min
POST-SBR EQUALIZATION VOLUME DETERMINATION
The volume required for equalization/storage shall be provided between the high and the low water levels of the basin(s). This
Storage Volume (Vs) has been determined by the following:
The volumes determined in this summary reflect the minimum volumes necessary to achieve the desired results based upon the
input provided to Aqua. If other hydraulic conditions exist that are not mentioned in this design summary or associated design
notes, additional volume may be warranted.
Vs = [(Qd -(MDF x 694.4)] x Td = 72,530 gal = (9,696.5 ft³) = (274.6 m³)
Based upon liquid level inputs from each SBR reactor prior to decant, the rate of discharge from the Post-SBR Equalization basin
shall be pre-determined to establish the proper number of pumps to be operated (or the correct valve position in the case of
gravity flow). Level indication in the Post-SBR Equalization basin(s) shall override equipment operation.
POST-SBR EQUALIZATION BASIN DESIGN VALUES
No./Basin Geometry:
= 1 Rectangular Basin(s)
Length of Basin: = (13.4 m) = 44.0 ft
Width of Basin: = 21.0 ft = (6.4 m)
Min. Water Depth: = (0.5 m) = 1.5 ft Min. Basin Vol. Basin: = 10,367.3 gal = (39.2 m³)
Max. Water Depth: = 12.0 ft = (3.7 m) Max. Basin Vol. Basin:
= 82,897.3 gal = (313.8 m³)
POST-SBR EQUALIZATION EQUIPMENT CRITERIA
Mixing Energy with Diffusers:
= 15 SCFM/ft² of reactor
SCFM Required to Mix: = 166 SCFM/basin = (282 Nm³/hr/basin)
Max. Discharge Pressure: = 5.8 PSIG = (39.77 KPA)
Max. Flow Rate Required Basin: = 604 gpm = (2.287 m³/min)
Avg. Power Required: = 103.4 kW-hr/day
