Abstract
The invention provides a reactor apparatus including a fluid bed reactor containing a media bed composed of particulate solids and biomass adhered thereto. The reactor apparatus also includes a biomass monitoring system for measuring changes in the size of the media bed and for activating a biomass growth control system when conditions with the reactor call for removal of excess biomass. The biomass monitoring system includes a vertical tubular member that is supported in the reactor and that serves to isolate a parameter or condition indicative of the size of the media bed. The biomass monitoring system also includes a sensing device for measuring changes in the isolated parameter or condition, and a mechanism for activating the biomass growth control system when signaled by the sensing device.
