ABSTRACT:
A centrifuge such as a continuous solid bowl centrifuge, for example, includes a rotatable bowl for receiving a slurry, and defines a zone in which the slurry is accelerated. The centrifuge includes a device such as a slurry feed tube for delivering slurry to the acceleration zone and a device for delivering a plurality of individual streams of flocculant solution coterminating with the slurry delivery device in order to uniformly distribute flocculant solution to the slurry.
