Anoxthane™

Anoxthane™ is based on industry proven MBBR technology. Advantages include:

• Smaller footprint compared to other biological systems
• Robust and stable in changing influent conditions
• Flexible for both upstream and downstream processes
• Easily upgraded for future loads
• Low to no maintenance required
• Easy to retrofit into existing infrastructure

 

The Anoxthane™ Process

An anaerobic biofilm grows on AnoxK™Z carriers to provide for controlled and protected biofilm development. The carriers are kept completely mixed and in suspension in the reactor volume by AnoxK™Mixer(s).

The AnoxK™Mixer is specially designed for MBBRs using AnoxK™Z carriers, optimized to work seamlessly together. The anaerobic biofilm removes the biodegradable solution, transforming it into biogas.

 

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

 

Anoxthane™ Carefully Selected Components

Anothane™ comes as a complete solution, custom designed to meet your specific needs.  All AnoxK™ components are optimized to work seamlessly together as a single unit.

 

Included in Anoxthane™ technology are:

• One-stage AnMBBR with AnoxKaldnes™ outlet sieves
• AnoxK™Z carriers for controlled anaerobic biofilm growth and robustness against scaling
• Top-mounted mechanical AnoxK™Mixer
• Optional post-aerobic polishing MBBR

 

Benefits of an Anoxthane™ AnMBBR for anaerobic wastewater treatment

Robust

• 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

 
Flexible

• 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
• Retrofit tanks or malfunctioning anaerobic reactors
• No digestion of solids in the wastewater reactor.  Possibility to integrate with solids separation and more efficient solids digestion
