1.12.5 Flotation. Flotation is a separation process in which air or gas bubbles are directed at the solid particles and then drive these particles to the liquid surface. Flotation is more beneficial and efficient for removing cells than sedimentation. Flotation can capture particles smaller than 500 μm in diameter (Chen et al., 2011).
