To control the operation of a flotation cell, especially for deinking used paper fiber suspensions, a control circuit (11) sets the liquid level in the cell suspension holding zone (1), and a control circuit (10) sets the foam (2) level. At least one quality characteristic is measured (12) in the cleaned suspension outflow (4) to set the nominal liquid and/or foam levels. The quality characteristic includes whiteness, brightness, color type, the number of soiled points and/or stickies. |
