Column flotation deinking is a critical sub-system in paper recycling to produce the highest quality product at low cost. Among the benefits of column flotation are higher selectivity, smaller floor space requirement, lower capital cost and reduced operating and maintenance costs (Finch and Dobby, 1990).Vertical columns result in considerable floor space …
In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).
