treated using a continuous-flow, activated sludge reactor to develop an acclimated culture of activated sludge. The desired amount of acclimated sludge was placed in a batch reactor, and the reactor was operated over a 24-hour duration to obtain data for kinetic evaluations. The observed cod and miss concentrations are shown in Table 1. The mlvss = 0.85 mlss, the bod5 = 7 mg/l, and the bod5 = 0.36 bodu, at 24 hr. The bodu, = cod (biodegradable). a. Determine the nondegradable cod and plot the concentration of mixed liquor suspended solids, X, and the biodegradable cod2 C, versus time. t, on arithmetic paper. Is a lag phase evident? b. Determine the reaction order and rate constant on the basis of both mlyss and mlss if the substrate concentration is represented by the biodegradable cod. Note: Do not include the 8-hour and 24- hour values in the plot for the reaction order and rate constant, because the cod values are too low to be representative
