Q1: An activated sludge treatment plant treats a sewage at a flow of 3*103 m³/day with a BOD of 350 mg/l and returned sludge 20%. The dimension of the aeration tank is 25 m long, 10 m width and 4 m depth. The concentration of the mixed liquor suspended solids (MLSS) is 2500 mg/l. Calculate the F/M ratio, Detention time, Organic load.
The aeration tank influent flows at a rate of 1600 cu.m/day with BOD(biochemical oxygen demand) of 145 mg/L. The MLSS is around 200 mg/L. If the capacity of the aeration tank is 2000 cu.m, determine which of the following statements is true. a) The aeration tank is not operating in an ideal condition; there are excess bacteria that might go with the treated water b) The aeration tank is operating in good condition; BOD and bacteria are in ideal balance c) The aeration tank is operating in good condition; however, there is a need to control the flow rate of the feed d) The aeration tank is not operating in an ideal condition; need to add more bacteria to treat excess BOD
The saturation DO concentration of a stream is 9.1 mg/L. At a sewage outfall, the DO of the stream is 8.0 mg/L. The stream has a reaeration constant of 4/day and a deoxygenation rate constant of 0.1/day. The initial ultimate BOD in the mixing zone is 200 mg/L. The time after the discharge at which the water will reach its minimum DO is most nearly a) 1.0 hr b) 1.7 hr c) 21 hr d) 34 hr e) calculate the minimum DO (in mg/L).

A secondary clarifier handles a total flow of 9600 m³/d from the aeration tank of a conventional activated-sludge treatment system. The concentration of solids in the flow from the aeration tank is 3000 mg/l. The clarifier is required to thicken the solids to 12000 mg/l, and hence it is to be designed for a solid flux of 3.2 kg/m²h. The surface area of the designed clarifier for thickening (in m², in integer)
The 8-day, 20°C BOD of a wastewater (K = 0.27 /day) is 247 mg/L. What is the ultimate BOD (BODy, Lo, in mg/L)? Provide your answer to the tenths place (0.1).
There is sedimentation tank that is used to remove suspended solid particles from an incoming wastewater stream. The incoming wastewater has a flowrate of 150 m³/hr and the sedimentation tank has a basin surface area of 15 m2. Assume the operation temperature is 25 C and assume that sedimentation is the only process by which suspended solid particle are removed from the sedimentation tank. a) What is the settling velocity of the suspended solids in this sedimentation tank in the unit of m/s
