After industrial wastewater enters the reactor, it is thoroughly mixed with granular anaerobic sludge in the distribution system. The organic matter is converted into biogas.
The biogas is collected in the lower phase separator, creating an “upward gas lift effect” that drives the liquid to flow upward through the riser pipe. The biogas is discharged from the reactor through a gas-liquid separator, while the liquid flows back to the distribution system via the downcomer — this is the origin of the “internal circulation.
The upper reaction zone further purifies the effluent, while the biogas produced in the upper zone is collected in the upper phase separator. The treated wastewater is discharged from the reactor, and the biogas is collected for centralized reuse.
