3 The high-purity-oxygen process illustrated in Figure 12.39 is being considered for treat- ment of an unsettled domestic wastewater flow of 1.40 mgd with an average BOD of 200 mg/l. Compute the aeration volume required based on a maximum allowable BOD load- ing of 130 lb/1000 ft³/day and minimum aeration period of 1.8 hr. For this system, what is the F/M ratio in terms of lb of BOD/day/lb of MLVSS, assuming an MLSS of 5500 mg/l, lotila?

3 The high-purity-oxygen process illustrated in Figure 12.39 is being considered for treat-
ment of an unsettled domestic wastewater flow of 1.40 mgd with an average BOD of 200
mg/l. Compute the aeration volume required based on a maximum allowable BOD load-
ing of 130 lb/1000 ft³/day and minimum aeration period of 1.8 hr. For
this
system,
what is
the F/M ratio in terms of lb of BOD/day/lb of MLVSS, assuming an MLSS of 5500 mg/l,
lotila?
