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…

C A trickling filter plant treats 1500 cum per day of sewage with a BOD, of 220 mg/L and a suspended solid concentration of 250 mg/L. Estimate the total solid production assuming that primary clarification removes 30% of BOD and 60% of influent solids. Take the solid production in the trickling filter as a 0.5 kg/kg of the applied BOD.
3. A 100 mL of wastewater sample was drying on a 0.5 g empty dish weight at 104 °C to weight 0.5625 g. Another 100 mL of the same wastewater was first filtered and the filtrate was dried on a 0.5 g dish at 104 °C to weight 0.5325 g. Determine in mg/L the:a) TSb) TSSc) TDSd) VSS assuming it represents 70% of TSS
The 750-bed Associated Center of Medical Excellence (ACME) Hospital has a small activated sludge plant to treat its wastewater. The average daily Medical Center discharge is 1,250 L per day per bed, and the average soluble BOD5 after primary settling is 450 mg/L. The aeration tank has effective liquid dimensions of 10.0 m wide by 25.0 m long by 3.5 m deep. The plant operating parameters are as follows: MLVSS = 2,750 mg/L MLSS = 1.25 (MLVSS) Settled sludge volume after 30 min = 250 mL/LDetermine the following: aeration period, F/M ratio, SVI, solids concentration in return sludge.
A one cell rapid sand filter tank has a loading rate 9.0 m/h, surface dimensions of 15*6 m. The sand and gravel depths are 70 cm and 60 cm respectively. The height of wash trough is 50 cm and the height of water above surface of sand is 2.0 m. Note that Shape factor of sand is 0.80 and stratified bed porosity is 0.50. a) What flow rate (m³/sec) does the filter handle during production? b) What is the total height of filter basin (m)? c) Calculate the head loss if the value of this term [2 (Co fid)] equal to 105700. d) In your opinion this filter tank specified the Saudi specifications?
