DESIGN INFLUENT CONDITIONS
Avg. Design Flow
Max Design Flow
= 0.435 MGD = 1644 m³/day
= 0.87 MGD
= 3289 m³/day
Pre-Filter Treatment: SBR
= 302.08 gpm
= 604.2 gpm
The filtration system shall be designed based upon flow equalization after the SBR and prior to filtration.
DESIGN PARAMETERS
Influent mg/l Required <= mg/l Anticipated <= mg/l

Avg. Total Suspended Solids:
5 TSSa 10 10 TSSa TSSa
Max. Total Suspended Solids:
TSSm 15 -- -- -- --
Phosphorus: Total P 0.30 -- -- -- --
Bio/Chem Oxygen Demand: CBOD 4.50 CBOD CBOD 4.50 4.50

AquaDISK FILTER CALCULATIONS
Filter Type:
Total Number Of Disks Recommended
Total Filter Area Provided
Filter Model Recommended
= 1
= 2
= 2
= 107.6 ft² = (10.00 m²)
= AquaDisk Package: Model ADFSP-54 x 2E-PC
Filter Media Cloth Type
= OptiFiber PA2-13
Vertically Mounted Cloth Media Disks featuring automatically operated vacuum backwash . Tank shall include a rounded bottom
and solids removal system.
Average Flow Conditions:
Average Hydraulic Loading
Maximum Flow Conditions:
Maximum Hydraulic Loading
= Avg. Design Flow (gpm) / Recommended Filter Area (ft²)
= 302.1 / 107.6 ft²
= 2.81 gpm/ft² (1.91 l/s/m²) at Avg. Flow
= Max. Design Flow (gpm) / Recommended Filter Area (ft²)
= 604.2 / 107.6 ft²
= 5.61 gpm/ft² (3.82 l/s/m²) at Max. Flow
Solids Loading:
Solids Loading Rate
= (lbs TSS/day at max flow and max TSS loading) / Recommended Filter Area (ft²)
= 108.8 lbs/day / 107.6 ft²
= 1.01 lbs. TSS /day/ft² (4.93 kg. TSS/day/m²)
