A WWTP utilizing the cоmplete-mix mоdificаtiоn of the аctivаted sludge process is located at 1,000 FMSL. The oxygen demand for the facility is 9,625 lb O2/day during the summer months when the maximum wastewater temperature is 84.2 ° Four mechanical aeration devices are to be used and the aerator manufacturer has determined the oxygen transfer to be 2.3 lb O2/hp-hr. Determine the theoretical aerator power (hp) per aerator if the operating DO is 1.8 mg/L. Assume α and β values of 0.75 and 0.95, respectively. (5 pts) Determine saturation dissolved oxygen concentration of the wastewater (Cw) (unit: mg/L) (5 pts) If Cw is 7.12 mg/L, determine rate of oxygen mass transferred (N) (unit: lb O2/hp-hr) (5 pts) If the rate of oxygen mass transferred is 1.196 lb O2/hp-hr, determine aerator horsepower required (each)? (unit: hp)
