5. A preanoxic process is applied to treat municipal wastewater. The wastewater treatment plant wants to build two identical secondary clarifiers that operate in parallel and the effluent flowrate from the aeration tank is equally divided between the two clarifiers. You are hired as consultant to determine the impact of having two secondary clarifiers that operate in parallel as opposed to having only one. Splitting the flowrate equally between the two clarifiers is the only change. (20 points) Sketch the steady-state profile of the parameters indicated below when there is one clarifier versus when there are two operating in parallel and briefly explain your answer. Note: Please sketch the answer for the one clarifier and two clarifiers on the same figure and label the lines clearly. Plot time as the x-axis and each parameter as the y-axis. (a) Effluent concentration of waste sludge (Xw) (b) Solids production rate (Px.vss) (c) Effluent concentration of NH4-N (Ne,NH4) (d) Solids retention time (SRT) 5.
