Flotation Process an overview ScienceDirect Topics

In flotation process, the gas or air bubbles are introduced through culture suspension, and the microalgal biomass get attached to gaseous molecules and accumulated on the liquid surface. This method is particularly effective for thin microalgae suspension that could be simply gravity thickening.

FLOTATION

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm. The particle-bubble aggregates that are formed have a density less than the suspension itself

The Flotation Process Can Go Green MDPI

2019-3-6  A green flotation method for the separation of small amounts of boron from aqueous solution was published [17]. Hence, the aforementioned selected examples from the literature perhaps already indicate that flotation can go green. Flotation is, in principle, a surfactant-based separation process, where the surfactants are usually termed collectors.
