The larger conventional flotation cells are also more energy efficient in that the total energy per unit volume is reduced. However, this is contrary to previous work which has shown that high specific energy input is required to improve the flotation kinetics of fine and/or slow floating particles (Mankosa et al, 2016).For example, conventional mechanical flotation …

Additionally, high load was susceptible to sludge flotation during anaerobic operation (Tan et al., 2020). Meanwhile, denitrifying and anammox sludge particles were prone to sludge flotation when the NLR was greater than 65.00 kgN m −3 d −1 and 62.00 kgN m −3 d −1, respectively (Chen et al., 2014; Li et al., 2014).
