WebJun 10, 2024 · The morphology of FGS was characterized via SEM and optical microscope observation, as shown in Figure 4 Filamentous granular sludge was between 0.64 mm and 2 mm. Filamentous bacteria were growing on the surface of granular sludge and the diameter of the filamentous bacteria was 0.4–0.7 μm and the length of the filamentous … 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.
