ADI-Hybrid Reactor

Source: Paques ADI Inc.
The Hybrid reactor is a high-rate system that combines two anaerobic processes - the UASB (upflow anaerobic sludge blanket) on bottom and UFF (upflow fixed-film) on top - and retains the process advantages of each. It also requires less space than other treatment methods.

  • Space-Saving, High-Rate Reactor
    The Hybrid reactor is a high-rate system that combines two anaerobic processes - the UASB (upflow anaerobic sludge blanket) on bottom and UFF (upflow fixed-film) on top - and retains the process advantages of each. It also requires less space than other treatment methods.

  • Dense Sludge Bed is Unnecessary
    The reactor circumvents one major shortfall of the UASB, namely, the need to generate and maintain dense, granular sludge (essential for process stability). Overlying media intercepts solids, promotes flocculation, and returns solids to the sludge bed below.

  • Stable and Resilient to Shocks
    The advantages of combining UASB and UFF processes are high loading rates (10-20 kg COD/mad) and excellent hydraulic characteristics and substrate-bios contact. The additional biosolids inventory increases the reactor's removals, process stability, and ability to handle toxic shocks.

  • Consistently High-Quality Effluent
    BOD removals can reach 90-95 percent at 30-35°C, and effluent SS levels are usually low because of the overlying media. This reactor produces a consistently high-quality effluent because of its ability to maintain a high biological solids inventory.
