Flotation Cellan overview ScienceDirect Topics

The mechanical complexity makes mechanical induced flotation units the most maintenance-intensive of all gas flotation configurations. As a result of the need for motor shaft seals on penetrations to the cell, mechanical induced flotation units have traditionally operated very near atmospheric pressure.
