Anoxthane™ (AnMBBR)

Industry-proven anaerobic technology by biofilm
A flexible and robust solution for treating wastewater at anaerobic conditions and relative low temperatures

Anoxthane™ AnMBBR (Anaerobic Moving Bed Biofilm Reactor) is a technology solution that allows for the anaerobic treatment of wastewaters containing different levels of  COD (Chemical Oxygen Demand) and solids. It works at different temperatures and offers increased robustness against variations in organic loads and temperature compared to  suspended and granular-based anaerobic technologies.

Anoxthane™ is beneficial for water with the following characteristics:

  • Low-strength wastewater with a large fraction of soluble, easily degradable COD
  • Cold or warmer temperature effluents (20-38oC) without the need for heating
  • Wastewater with higher levels of solids and fats/oils where anaerobic granular technologies are not very efficient

Features and benefits

  • Simple and flexible reactor design at different scales
  • Ease of implementation and operation
  • Operational at various temperatures (mesophilic, thermophilic or colder temperatures) 
  • Control COD removal capacity based on media filling degree
  • No digestion of solids in the wastewater reactor.  Possibility to integrate with solids separation and more efficient solids digestion
  • Lower risk of biomass losses due to the formation of an attached biofilm to carriers
  • Resilient to variations in loads and temperature due to a stable and fixed biofilm
  • Tolerance against high levels of incoming solids and fats
  • Reduced impacts of scaling in the MBBR operation and no risk of clogging from excessive biomass growth or accumulation of foreign particles provided by AnoxK™Z carriers
