The linear structure of the flotation cells has a large surface area, which has reject separation and fiber loss. This flotation cell design also contributes to high sludge consistency (less water in the sludge) by ensuring smooth drainage of froth (Aksela, 2008). The elliptical shape of the flotation cells in this technology is optimal for internal pulp circulation for improved ink removal. Moreover, the flatness of

Advances in Flotation Unit Design for Produced Water

21/03/1993  Flotation units have been widely used for the treatment of produced water both onshore and offshore. They have, however, exhibited numerous operational and performance limitations. Over the past several years, new designs for the treatment of produced water by flotation have been developed. These have resulted from years of intensive research in both the laboratory and at oil production
