Simulation of Floc Size Distribution in Flocculation of Activated Sludge Using Population Balance Model with Modified Expressions for the Aggregation and Breakage

Figure 1

Simulated steady-state floc size distribution by using the four models under different velocity gradients (simulation results in the previous paper [22] were shown in Method 2).

(a) G = 28.2s⁻¹

(b) G = 64.7s⁻¹

(c) G = 101.7s⁻¹

(d) G = 149.8s⁻¹
