Flotation deinking is a key unit operation in most paper recycling plants for the removal of hydrophobic contaminants from pulp [12]. There is a wide variety of flotation cells available for deinking but the dominant technology typically consists of multiple horizontal flotation cells in series, with each cell being aerated by several injectors.

In this model, a flotation cell consists of different regions representing perfect mixing, dead volume, by pass, recycling and plug flow. The main reason cited for the existence of stagnant portions of the flotation machines is insufficient turbulence. This portion of the machine is usually located in the corners and upper part of the vessel.

A typical flotation column is shown in Figure 13. The basic principle of column flotation is the use of countercurrent flow of air bubbles and solid particles. This is achieved by injecting air at the base of the column, and feed near the midpoint. The particles then sink through a rising swarm of air bubbles.
