Anaerobic processes

Anaerobe wastewater treatment is a proven technology for treating wastewater with high levels of organic contamination.

Resource-saving wastewater treatment with a high degradation rate and energy recovery

Anaerobic processes for wastewater treatment are biological processes in which organic contaminants are converted into biogas and thus removed from the wastewater. Anaerobic processes are characterised by high degradation rates as well as minimised electricity consumption and sludge generation. Using the biogas produced in the form of electricity or heat reduces the activity’s CO2 footprint, while high volume-specific conversion rates mean minimal space requirements.

The benefits of our Biomar® technologies are:

  • Biogas and energy production instead of sludge production
  • Improved CO2 footprint
  • Cost savings on wastewater charges (heavy polluters) due to high COD reduction
  • Compact design, low reactor volume – small footprint
  • Reactor types available for every application

Our Biomar® product range includes:

  • Fixed-bed reactors
  • High-performance reactors
  • High-performance sludge-bed reactors (EGSB, Expanded Granular Sludge Bed)
  • Contact biology (CSTR, Continuous Stirred Tank Reactor)
  • Treatment with loop reactors
  • UASB (Upflow Anaerobic Sludge Blanket) process
  • Contact biology with biomass recycling
  • Membrane biology 
  • Aerobic processes 

Our experts select the appropriate time-tested Biomar® process and technology combinations for your specific requirements.
