Question 2

Calculate the BOD Loading (lbs/1000 ft3/day) and the Hydraulic loading (gpm/ft2) of a single stage tricking filter based on the following data:


Average Raw Wastewater Flow Q = 450 gpm

Recirculation Ratio Qr = 50%

High Water Temp. = 64 F

Low Water Temp. = 55 F

Settled Wastewater BOD (Primary Effluent) = 135 mg/l

Diameter of the Filter = 70 feet

Depth of the Media = 8 feet

BOD Loading:           23.7 lbs/1000 ft3/day

Hydraulic Loading:  0.17 gpm/ft2

BOD Loading:           35.4 lbs/1000 ft3/day

Hydraulic Loading:  0.11 gpm/ft2

BOD Loading:           0.02 lbs/1000 ft3/day

Hydraulic Loading:  0.11 gpm/ft2

Correct Answer not shown

BOD Loading:           35.4 lbs/1000 ft3/day

Hydraulic Loading:  0.17 gpm/ft2

Top Answer

Hydraulic Loading Rate = Flow rate in Gpm/ surface... View the full answer
