Method and plant for removing impurities from an aqueous suspension of fibrous matter |
摘要 |
<p>To clean a watery fibre suspension (1,1') of undesired matter, it is passed through a series of selective flotation stages with at least one mechanical processing station between them. The suspension (1) is given a flotation in at least two successive part-stages where one (2,2') has a weaker action than the other (3,3'). Also claimed is an assembly where the suspension is passed through a flotation cell which works selectively with gravity, and also through a flotation cyclone.</p> |
