<p>Biological treatment of suspension, comprises circulating the suspension, where some are routed through vertically aligned guide zone so that vertical flow of portion of suspension is produced, which flow proceeds into area of suspension fill level or from area of suspension fill level; and feeding fluid in area of suspension fill level to cause rotary flow of surface of suspension and/or of top scum floating on surface of suspension. An independent claim is also included for a bioreactor for biological treatment of a suspension comprising in the interior of the bioreactor, a guide with a vertical alignment for circulating the suspension, and at least one nozzle (11, 13) for feeding a fluid into the bioreactor in the area of the suspension fill level.</p> |
