Optimizing mixing mode and intensity to prevent sludge flotation …
Sludge flotation potential (SFP) is an important parameter indicating the tendency of sludge to float in an upflow bioreactor (Yoda and Nishimura, 1997, Halalsheh et al., 2005). The flotation potential of the sludge in the twelve tests was determined and the results are shown in Fig. 5. The SFP declined from 73 ± 5%, 79 ± 8%, and 75 ± 4% …
