In flotation deinking the goal is to remove ink and other hydrophobic contaminates from recycled paper furnish. This unit is very good at removing the small toner particles from laser printed mixed office waste. The flotation cell is operated at about one percent consistency using a surfactant to help create bubbles. Air is pumped into the center of the cell creating bubbles. Ink particles attach to the bubbles and together float to the surface of the cell. The cell contains paddles that remove the resulting foam. Surfactant levels are nominally in the range of 0.3 to 1.0 percent.
