Abstract:
     A process and a device for biological treatment of a suspension in a bioreactor ( 2 ) are described. To circulate the suspension, at least some of the suspension is routed through a vertically aligned guide zone ( 5 ) so that a vertical flow of the suspension is produced. To control sediment problems, it is suggested that by feeding a fluid, especially a free liquid jet, via at least one nozzle ( 11 ), a horizontal flow is superimposed on the vertical flow in the vicinity of the bottom of the bioreactor ( 2 ), by which a spiral flow to the central outlet area of the bioreactor ( 2 ) is produced.
