23-3. The town of Camp Verde has been directed to upgrade its primary WWTP to a secondary plant
that can meet an effluent standard of 25.0 mg/L BOD5 and 30 mg/L suspended solids. They have se-
lected a completely mixed activated sludge system for the upgrade. The existing primary treatment
plant has a flow rate of 2,506 m³/d. The effluent from the primary tank has a BOD5 of 240 mg/L. Using
the following assumptions, estimate the required…

- The single degree of freedom (SDOF) system that you studied under free vibration in Assignment #3 - Laboratory Component has been subjected to a strong ground motion. The acceleration at the base (excitation) and the acceleration at the roof (response) of the SDOF system was recorded with sampling rate 50 Hz (50 samples per second, or dt= 0.02 seconds). The file ElCentro.txt includes the two columns of acceleration data. The first column lists the acceleration at the base of the SDOF system. The second column lists the acceleration at the roof of the SDOF system. (a) Plot the time histories of the recorded accelerations at the base and at the roof of the SDOF system. (b) Compute the acceleration, velocity and displacement time histories of the roof of the SDOF system subjected to the recorded base acceleration using the Central Difference method.
