Abstract (en)
[origin: EP4008690A1] Biomass recirculation unit for an anaerobic purification apparatus of fluid, comprising: an inlet system configured to receive influent fluid from outside, a biomass collecting system for drawing off biomass from a middle section in the reactor tank and bringing the biomass into the biomass recirculation unit, a mixing segment for being connected to the inlet system and the biomass collecting system, and for receiving and mixing the influent fluid and the biomass, and an outlet system for discharging a mixture of the influent fluid and the biomass into the lower section of the reactor tank, the inlet system comprising a constricted nozzle for, as the influent fluid flows from the inlet system to the mixing segment through the constricted nozzle, creating a suction effect causing the biomass collecting system to draw off the biomass from the middle section of the reactor tank into the mixing segment.
