WATER CLARIFICATION BY FLOTATION -1

The apparatus used is generally termed a flotation cell and when surface-active agents, such as 'collectors' and frothing agents, are employed, the process is known as froth flotation. Alternatively, a gas and liquid stream may be homogenized or air may be diffused through suitable porous media. Dispersed-air flotation systems produce air

Froth Flotation Process Diagram

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
