    The effect of flotation cell shape on deinking behaviour

    Vertical injection into a rectangular cell gave stable flow patterns, nonwavy froth removal and sustained brightness lift for a wide range of feed and airflow rates. Horizontal injection into a similar rectangular shaped cell exhibited quite different characteristics. High brightness lift was possible for certain conditions and not for others.
