Abstract
A rotating biological contactor apparatus includes: a biozone tank containing a liquid being treated; a drive shaft driven to rotate; and at least one media disk. The media disk includes: a substrate having a disk shape defining a first surface and a second surface opposite the first surface, the substrate configured to be attached to the drive shaft and to rotate therewith; and a plurality of fins protruding from at least one of the first surface and the second surface of the substrate and extending for a length in a radial direction to generate a turbulent flow as the plurality of fins pass through a surface of the liquid being treated as the media disk rotates.

A media disk for a rotating biological contactor apparatus, comprising:
- a substrate having a disk shape defining a first surface and a second surface opposite the first surface, the substrate configured to be attached to a drive shaft and to rotate therewith;
- and
- a plurality of fins protruding from at least one of the first surface and the second surface of the substrate and extending for a length in a radial direction to retain a biomass thereupon,
- wherein the plurality of fins are arranged in a plurality of concentric rings on the at least one of the first surface and the second surface of the substrate, and
- wherein, when the media disk is rotated, the plurality of fins of the plurality of concentric rings are configured to direct fluid flow radially inwardly toward a center of the media disk, thereby increasing surface area for oxygen transfer and lengthening contact time between oxygenated water and the biomass.
