The wastewater from a synthetic textile manufacturing plant is discharged to a municipal treatment plant for processing with domestic wastewater. The characteristics of the synthetic textile wastewater are 1500 mg/L BOD, 2000 mg/L SS, 30 mg/L nitrogen, and no phosphorus. The characteristics of the domestic wastewater are 200 mg/L BOD, 240 mg/L SS, 35 mg/L nitrogen, and 7 mg/L phosphorus. Find the BOD, SS, nitrogen, and phosphorus concentrations in the mixture. Note: The ratio of flow rate is domestic/textile = 4/1

What additional of NH4OH and H3PO4 would be required in pounds per million gallons of wastewater to provide the necessary nutrient levels for the treatment of the manufacturing wastewater described above (a) if the domestic wastewater had not been combined with it.
The density of water at 4°C is 1000 kg/m3 at atmosphericpressure. The gravity acceleration constant (g) is 9.81 m/s2. Thespecific gravity of an industrial wastewater (SGww) is 1.32. Whatis the specific weight of this wastewater?
As an operator of a wastewater treatment facility, you have learned that your plant runs well at an SRT (based on MLVSS (X) in the aeration basin) of 12 days. If today’s MLVSS (X) concentration is 2,700 mg/L and the RAS (Xr) concentration is 5,500 mg/L, how many L of sludge should you waste from the secondary clarifier today? Other design conditions: Average influent flow = 12,000 m3/d Influent soluble BOD = 150 mg/L Required effluent TSS = 30 mg/L Aeration tank Volume = 1,000 m3
If a manufacturing facility generates raw wastewater that is predominantly composed of dissolved and suspended solids and with ThOD of 100 mg/L, which of the following treatment equipment you could do away with? Check all that applies.
Please calculate the ThOD, COD, and ultimate BOD of a wastewater containing (a) 500 mg/L acetate (CH3COOH), which is fully biodegradable; or (b) 500 mg/L oil (C40H80), which is not biodegradable.
A wastewater treatment plant discharges 2.16x107 L/hr of treated effluent with an ultimate BOD of 22.0 mg/L and dissolved oxygen concentration of 5.0 mg/L to a river. Upstream of the waste discharge, the river has a flow of 9.0 m3/s, an ultimate BOD of 10.0 mg/L, and dissolved oxygen concentration of 7.0 mg/L. Both the river and effluent are at 20°C. After the river and effluent mix, the river flows at a velocity of 0.13 m/s and has a depth of 1.8 m. The deoxygenation rate constant for the waste is 0.45 day-1. A fish hatchery is located 9.6 km downstream of the waste discharge. The hatchery requires 5.0 mg/L DO for healthy fish growth and reproduction. Is the hatchery requirement being met? show all work
