Question

A wastewater treatment plant is operated at a steady state DO concentration of
1.5 mg/L. If the temperature of the wastewater is measured at 10 °C, a= 0.8 and B = 0.95
and the KLa reported by the aerator manufacturer at 20°C in tap water is 5 hrt, estimate
the oxygen uptake rate (in mg/L-min) in the aeration basin. You can assume 0=1.024. If the
aerator's oxygen transfer efficiency is 24%, what would be the mass of air (kg) required per
hour in a 8500 m³ tank? What volumetric flow rate would you have to supply (m³/hr)?
