WebFilamentous bulking is common in completely-mixed, lower F/M systems. Here, a number of filaments can cause bulking (see Table 1) because they grow better than most activated sludge floc-forming bacteria at low aeration basin BOD concentration. Intermittently-fed and plug-flow systems are more resistant to this type of bulking.
