Flotation is commonly used in wastewater treatment technologies. During the flotation, the wastewater is aerated with air bubbles, while the particles of contamination form bubble-particle aggregates and rise into the froth layer [Prakash et al., 2018; Saththasivam et al., 2016]. The flo-tation process is quite complicated and depends
