Abstract
A reactor based on a generation of aerobic granules in a continuous flow configuration, for biological treatment of biomass including urban or industrial wastewater, the reactor including, in succession, from upstream to downstream: an inlet for wastewater; a first head tank operated in feast mode and under anaerobic conditions; a second tank for performing a function of a biological selector for microorganisms which are favorable to formation of dense structures, operated in feast mode, and subdivided into two compartments, a first compartment being operated successively and alternately under aerobic and anaerobic conditions and vice versa, so that the biomass is exposed in a dynamic way to alternating oxidizing and reducing conditions respectively, and so as to prolong or extend anaerobiosis of the first head tank into the first compartment of the second tank.
