The preliminary design for a wastewater treatment plant is being developed. The wastewater flow rate is 10,000 m3/day, and the BOD5 concentration is 200 mg/L. The plant discharge standard is 30 mg/L as BOD5. Experience suggests that stable and reliable compliance with this discharge standard can be achieved using an SRT of 5 days. No primary clarifiers are to be provided. For the purpose of this assessment, the wastewater temperature can be assumed to be 20oC. Make a preliminary assessment of the size of bioreactor required if the MLSS concentration is maintained at 2500 mg/L as TSS. Assume that 75% of the MLSS is volatile. Also estimate the kg/day of solids that must be disposed of and the kg/day of oxygen that must be supplied.
