A conventional activated sludge plant treating a domestic flow of 150 ML/d is operated at a SRT of 10 d with a MLVSS of 3500 ppm. The activated sludge plant is required to reduce the influent BOD from 200 ppm to less than 10 ppm prior to discharge. The discharge from the aeration basin is clarified, such that the clarifier overflow contains no particulate material and the MLVSS of the recycle stream is 8000 ppm. You are required to determine...

Sooner City Reclamation Plant is a completely mixed activated sludge process designed to treat 20,000 m3/d of domestic wastewater having an influent BOD5 concentration of 350 mg/L (assume a 28.6% reduction in during primary treatment). Use typical activated sludge kinetic constants except for kd = 0.06 1/d. Assume that the MLVSS concentration in the aeration basin is maintained at 3,000 mg/L and the ratio of VSS:TSS is 0.75. Permit requires that the effluent BOD5 and TSS concentrations do not exceed...

A wastewater treatment plant that treats wastewater to secondary treatment standards uses a primary sedimentation process followed by an activated sludge process composed of aeration tanks and a secondary clarifiers. This problem focuses on the activated sludge process. The activated sludge process receives a flow of 15 million gallons per day (MGD). The primary sedimentation process effluent has a BOD5 concentration of 180 mgBOD5/L (this concentration is often referred as S). Before flowing into the activated sludge process, the primary...

Estimate the volume of air to be supplied (m3/d) for an activated sludge system with a flow of 0.25 m3/sec, net waste activated sludge production of 340 kg/day VSS, and an influent soluble BOD5 of 74 mg/L. Assume that soluble BOD5 is 58% of BODL, BOD5 in the aeration tank is 14 mg/L, and that the oxygen transfer efficiency is 9%. Density of air is 1.185 kg/m3, and air has 23.2% oxygen.

A completely mixed activated-sludge process is being designed for a wastewater flow of (2.64 mgd) using the kinetics equations. The influent BOD of 120 mg/Lis essentially all soluble and the design effluent soluble BOD is 7 mg/L, which is based on a total effluent BOD of 20 mg/L. For sizing the aeration tank, the mean cell residence time is selected to be10 days and the MLVSS 2000 mg/L. The kinetic constants from a bench-scale treatability study are as follows: Y...

Design a completely mixed activated sludge process using three different design approaches (i.e. calculate the volume of the aeration basin). Base your design for the first approach on detention time, for the second one on BOD loading, and the third one on kinetics. The influent design flow rate to the activated sludge process is 10,000 m3 /day with a BOD5 concentration of 200mg/L. Completely mixed activated sludge processes typically have a detention time ranging from 3 to 6 hours and...

The town of Camp Verde has been directed to upgrade its primary Waste Water Treatment Plant (WWTP) to a secondary plant that can meet an effluent standard of 25 mg/L BOD5 and 30 mg/L suspended solids. They have selected a completely mixed activated sludge system for the upgrade. The existing primary treatment plant has a flow rate of 0.029 m3/s. The effluent from the primary tank has a BOD5 of 240 mg/L. Using the following assumptions, estimate the required volume...
