benefits of twostage flotation in one compact design. In the onestage InjectaCell Compact, the reject from the primary cell is returned to a fiber recovery cell, where it is introduced directly into the foam layer where the fiber recovery takes place. This means that the functions of primary and secondary cells are combined in one cell.
