Mass cultivation and harvesting of microalgal biomass
Dissolved air flotation. Dissolved air flotation (DAF) is inverted sedimentation or a variation of flotation in which the liquid medium is sparged with air or gas bubbles generated at high pressure such that the solid particles attach to them and move towards the liquid surface from where they are recovered (Torres et al., 2017).

Flotation cells | SKF
Separating minerals in a froth flotation cell has a particularly corrosive effect on a slowly rotating rake and its components. Mixtures of slurry, surfactant, water, air and froth can quickly lead to failed seals and bearings. Which, of course, means costly unplanned downtime and lost productivity.
