Design a trickling filter system for BOD removal without the nitrification requirement, to treat municipal wastewater with an average flow of 200 m3/d (Qin) and influent BOD of 200 mg/L and Ammonium (NH4-N) of 42 mg/L. Make appropriate assumptions and use the design indicators for plastic media filters as given below. What are the possible effects of the peak flow of 1.5 times occurring once in a month? Volumetric loading rate (Bv)= 0.5 kgBOD/m3.d Volumetric loading rate for NH4-N (Bv, NH4-N)= 0.2 kgNH4-N/m3.d Hydraulic loading rate (qh= Q/AR)= 1.2 m/h Recirculation ratio (Qr/Qin) = 0.5

Question
Design a trickling filter system for BOD removal without the nitrification requirement, to treat municipal wastewater with an average flow of 200 m3/d (Qin) and influent BOD of 200 mg/L and Ammonium (NH4-N) of 42 mg/L. Make appropriate assumptions and use the design indicators for plastic media filters as given below. What are the possible effects of the peak flow of 1.5 times occurring once in a month?
Volumetric loading rate (Bv)= 0.5 kgBOD/m3.d
Volumetric loading rate for NH4-N (Bv, NH4-N)= 0.2 kgNH4-N/m3.d
Hydraulic loading rate (qh= Q/AR)= 1.2 m/h
Recirculation ratio (Qr/Qin) = 0.5
