摘要： The invention provides a fluid treatment apparatus including a fluid bed reactor. The fluid bed reactor includes a flow distribution system having a flow distributor for introducing untreated fluid into the reactor. The untreated fluid is introduced at a flow rate sufficient to generate an upflow velocity within the reactor that fluidizes the media bed within the reactor. The flow distribution system also includes a backflow prevention apparatus for supplying an auxiliary fluid to the flow distributer in the event flow of untreated fluid to the flow distributor is interrupted. The auxiliary fluid flushes the flow distributor while the media bed defluidizes to prevent the media bed from backing up into the flow distributor as it settles to the bottom of the reactor.

摘要： 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.
