Flotation in Water and Used Water Purification | SpringerLink

Flotation is commonly referred as the counterpart to sedimentation. The principle of flotation lies in attaching the suspended particles to air bubbles, thus driving them to the surface of the water against gravity for subsequent removal (Palaniandy et al. 2017; Kyzas and Matis 2018).For this, the suspended particles are subjected to a coagulation and flocculation …
