Design an aeration tank for activated sludge wastewater treatment designed to meet an effluent standard of 10 mg/L BOD₅. The flow from the primary effluent is 10 m³/min with a primary effluent BOD₅ of 250 mg/L. The design calls for the suspended solids to equal 3500 mg/L for an SRT of 5 days. The decay rate constant is 0.03 day^-1 and the yield is 0.75 mg/mg. Determine:

the tank volume required to meet these specifications,
the resulting mass of sludge wasted each day (kg/day), and
the F/M ratio.

A wastewater treatment plant with activated-sludge process treats wastewater for 120,000 m3/d. The effluent standard for both BOD and TSS is 20 mg/L. Influent TSS concentration is 450 mg/L and influent BOD concentration is 220 mg/L. MLSS concentration is 3500 mg/L (Assume no nitrification and temperature is 20°C). Determine: (20 pts) (a) Influent BOD and TSS concentration to the aeration tank if the treatment efficiencies in primary clarifier are 30% and 70% for BOD and TSS, respectively. (b) Determine sludge...

An activated sludge aeration blower is delivering air to diffusers in an aeration tank. You want to estimate the isentropic efficiency and the work input (by the motor). At the blower inlet, the volumetric flow rate is measured at 85 m3/min, the pressure is 0.98 atm and the temperature is 20⁰C. If the pressure is increased to 1.61 atm and the blower outlet temperature is 350 K: a) what is the blower isentropic efficiency, and b) what is the work...

An activated sludge process with an aeration basin volume of 0.3 MG is treating wastewater with the average daily flow of 2 MGD. The raw sewage entering the treatment plant has an average BOD5 of 400 mg/L. The primary treatment removes 25% of BOD5 and the subsequent activated sludge process is designed to remove 90% of BOD5. Given: Plant effluent BOD5 concentration = 30 mg/L Biomass concentration in the aeration tank = 2,000 mg/L Biomass concentration in the plant effluent...

Design a set of activated sludge aeration tanks. The flow rate to treat is 5.6 MGD and the BOD concentration is 150 mg/L. The design solids concentration (X) at steady-state is 2,000 mg/l. The design MCRT is 7 days. The kinetic coefficients are as follows: K = 2 g BODg cells⋅d, Ks = 25 BOD/L, Kd = 0.06 day-1, Y = 0.5 g BODg cells⋅d. The influent ammonia concentration is 40 mg/l and nitrification is needed. It takes 1400 ft3of...

Design an activated sludge treatment unit with the following data for a town of population of 80,000: B.O.D. of raw sewage = 200 mg/l. Per capita Average sewage flow is 180 liters. B.O.D. removal in primary treatment = 60%, Raw sludge retained in ASP = 25% Effluent water should have NO BOD at all to satisfy National Standards.

A 100-mL water sample is collected from the activated sludge process of municipal wastewater treatment. The sample is placed in a drying dish (weight = 0.5000 g before the sample is added), and then placed in an oven at 104°C until all the moisture is evaporated. The weight of the dried dish is recorded as 0.5625 g. A similar 100-mL sample is filtered and the 100-mL liquid sample that passes through the filter is collected and placed in another drying...

A wastewater plant with the activated sludge process received 5 × 106 L/day of wastewater with a BOD5 of 500 mg/L. The primary clarifier removes 30% of the BOD and primary clarify effluent has no biomass (Xi=0 mg/L). Recycle (Qr) and waste sludge (Qw) flows are 25% and 2% of Qin, respectively. Effluent BOD5 from secondary clarifier and waste sludge is 20 mg/L. Microorganism concentration in the waste sludge (Xw) is 6,000 mg/L. Soluble BOD5 is biologically converted into CO2...
