Using the following mass flow data from the Doubtful WWTP (Problem 20-7) determine Mass flows for Doubtful WWTP in Mg/d: A = 7.280, B = 7.798, D = 0.390, E = 8.910, F = 6.940, J = 4.755, K = 6.422, N = 9.428, X = 0.468.

Problem 20-7

The flow sheet for the Doubtful WWTP is shown in Figure P-20-7. Assuming that the appropriate values of η given in Figure 20-4 may be used when needed and that A = 7.250 Mg/d, X = 1.288 Mg/d, and N = 0.000 Mg/d, what is the mass flow (in kg/d) of sludge to be sent to ultimate disposal?
