Design an aerator system for Cynusoidal City’s equalization basin ( Problem 13-18 ). Assume that the aerators in Table 13-13 are available and that Figure 13-18 applies. To complete the design, specify the aerator by the unit’s power and provide a sketch of the plan view of the basin with the location of the aerators and the dimensions of the basin.

Problem 13-18

A treatment plant being designed for Cynusoidal City requires an equalization basin to even out flow and BOD variations. The average daily flow is 0.400 m³/s. The following flows and BOD₅ have been found to be typical of the average variation over a day. What volume equalization basin is required to provide for a uniform outflow equal to the average daily flow? Assume the flows are hourly averages and that an addition of 25% to the estimated volume will be provided to account for contingencies.
