WebDenitrification is achieved by three upflow, fluidized bed biofilm reactors. The reactor is designed for a loading of 3.0 kg of N0 3 −N per day per m 3 of expanded bed volume. The upflow velocity is 0.4 cm/s and the reactor has an empty bed contact time of 10 minutes at design flow. Each reactor has a design capacity of 7.5 Ml/d. WebThe influent nitrate-nitrogen concentration to the denitrification facility is normally in the range of 15 to 20 mg/L. Denitrification is achieved by upflow, expanded bed biofilm …
WebSuggested Kinetic Model for the Fluidized-Bed Biofim Reactor INTRODUCTION The fluidized-bed biofilm reactor (FBBR) is a novel biological wastewater treat- ment process in which the wastewater to be treated is passed upward through a bed of media, such as sand, at velocities sufficient to fluidize the media. Each media WebThe MeteorTM MBBR is a biological process with fixed fluidized cultures that keeps the micro-organisms in the reactors dedicated to a specific processing step, thus promoting the development of the purifying biomass. We thereby distinguish pre-denitrification from the elimination of carbon, nitrification and post-denitrification.
