The design maximum monthly flow for a conventional activated-sludge plant is 2.75 mgd with a BOD of 195 mg/1 and a suspended solids of 205 mg/l. Calculate the diameter and side water depth for two primary clarifiers. Using the loading and operational parameters listed in Table 11-2, recommend the required volume for the aeration tanks. Calculate the diameter and side water depth for two secondary clarifiers, F/M, and aeration period.
