Question
The step-acration activated-sludge system is to be analyzed as a series of continuous-flow stirred-tank reactors . Using the design parameters given below. determine the MLVSS concentration in each tank.
K = 240 m³
S₁ = 4 mg/L
S2 = 6 mg/L
S3 = 8 mg/L
S4 = 10 mg/L
So = 250 mg/L
Lo = 4000 m³/d
Q = 800 m³/d
X, = 10,000 mg/L
Y = 0.65
ka = 0.05
