An aeration basin of volume 200 m3 operates at a MLSS of 2500 mg/l. The daily sewage flow is 1500 m3 with an average BOD of 230 mg/l. The concentration of suspended solids in the effluent amounts to 60 mg/l. If the average waste sludge solid is 75 kg/d, compute the: a) Detention time in hours. b) F/M ratio. c) BOD sludge age or MCRT in days.

- An aerobic digester with a total capacity of 50,000 ft³ stabilize waste-activated sludge from an extended-aeration treatment plant without primary clarification. The average daily sludge flow pumped to the digestion tanks is 32,000 gpd with 1.5% solids, of which 65% are volatile. Calculate a) sludge detention time in the digesters b) the amount of sludge produced daily and c) the anaerobic digester dimensions. The population being served is 75,000. SS and BOD = 350 mg/l. %3D
The City of Marietta has been directed by the City Board to upgrade its primary Wastewater Treatment Plant (WWTP) to include a secondary treatment process that can meet an effluent standard of 20 mg/L of BODs and 20 mg/L of suspended solids (SS). They want to select completely mixed activated sludge system. The BOD5 of the SS is estimated to be 50% of the SS concentration. Assume L:W within 4:1 and maximum depth of 4.5 m and maximum length of 50 m for the tank. Assume the reasonable values of missing parameters from FE Exam Handbook. The effluent characteristics from the primary treatment process are: Flow = 0.150 m's, BOD5 =75 mg/L. Assume the values for the growth constants as K, = 100 mg/L BOD5, Mm = 2.5 d-1, kg = 0.05 d'1. Y = 0.50 mg VSS/mg BODs removed, MLVSS = 2,800 mg/L, MISS - 1.20 (MLVSS), wastewater temperature = 25.0°C. Assume 8% 02 transfer rate and BOD5 to BODu ratio as f = 68%. If SRT (qc) = 14.5 days, the volume of the aeration tank is nearly?

A factory is discharging its wastewater into a slowly moving stream that has a mean velocity of 3 cm/s. The flow rate of the stream is 4 times as that of the wastewater. The ultimate BOD of stream and wastewater are 5 mg/L and 105 mg/L, respectively. And DO of the stream and wastewater are 6 mg/L and 1 mg/L, respectively. The temperatures of the stream and wastewater are 15oC. The deoxygenation rate at 15oC is 0.48 day-1, and the re-aeration rate at 15oC is 0.72 day-1. Draw a DO sag curve to show your clients using Microsoft Excel. Please insert your DO sag curve into your project report (30 points); Based on your DO sag curve, find the location of and travel time to the critical point, and determine the minimum D A type of local fish requires the minimum DO in the river above 2 mg/L. Please evaluate whether the actual minimum DO is acceptable. If not, please qualitatively and quantitatively select appropriate management strategies to allow water quality to reach…
The rate of eradicating microbes through chlorination process is 0.22/min when the wastewater is flowing at a rate of 36 m3/h. If the depth of chlorination tank is 1.6 m and the width is 1.2 m, determine the required length of the tank to achieve 98% removal.
A sewage treatment plant receives sewage at a flow rate of 5000 m³/day. The total suspended solids (TSS) concentration in the sewage at the Inlet of primary clarifier is 200 mg/L. After the primary treatment, the TSS concentration in sewage is reduced by 60%. The sludge from the primary clarifier contains 2% solids concentration. Subsequently, the sludge is subjected to gravity thickening process to achieve a solids concentration of 6%. Assume that the density of sludge, before and after thickening, Is 1000 kg/m³. The dally volume of the thickened sludge (in m³/day) will be__
