Bioreactor Bio-R-95 is the only bioreactor in the world having a 95% Oxygen utilization.

Bio-R-95 is a High-Performance wastewater Bioreactor developed more than 20 years ago in Germany by experienced high level Biomedical experts specialized in Bioreactor technology.
This High-Performance Bioreactor is successful for many years in more than 150 wastewater treatment plants.


Our High-Performance Bioreactor reduces up to

90% COD

Our High-Performance Bioreactor reduces up to

99% BOD

Our High-Performance Bioreactor reduces up to

of the energy cost compared to conventional systems.

BIO-R-95 is excellent to treat and reuse/discharge

  • Communal wastewater
  • Industrial wastewater
  • Maritime wastewater in Ports and on board of ships (technology is IMO certified)
  • Liquid phase in the Livestock manure process (nitrification/denitrification)
  • Produced water in the Oil industry to remove dissolved oil, emulsions, BTEX components so ideal to use before UF/RO membrane filters.
  • Wastewater pharmaceutical industry removal of antibiotics

Bio-R-95 High Performance Bioreactor is the state-of-the-art biological wastewater treatment technology with a much more efficient and economical performance compared to Conventional biology, MBR treatment, MBBR treatment, SBR treatment, etc.

Even wastewater having a COD level >5000 ppm can be treated with this aerobic process.

This all combined with a low capital and operational cost.

With this High-Performance Bioreactor, the conventional biology flakes are manipulated in a way that the bacteria will be capable to utilize 95% of the oxygen.

Compared to conventional biological treatment having a maximum of 6-12% oxygen utilization this results in a tremendous increase of the biological strength and performance.

The 95% oxygen utilization gives clients the unique opportunity to solve many actual treatment and capacity issues they are dealing with.

Bio-R-95 makes it possible to reduce BOD/COD levels of 15 kg per m3 of water per day.

Based on this high capacity and biological power the installation has a very small footprint.

This high-performance biotechnology can be used to optimize an existing installation or can be used as leading technology in a new treatment plant.


Bioreactor Bio-R-95 is the only bioreactor in the world having a 95% Oxygen utilization.

Bioreactor Bio-R-95 is the only bioreactor in the world having a 95% Oxygen utilization. This results in a zero excess sludge build up as well. There will be no need to press/dry, transport and discharge/incinerate excess sludge which is a huge financial benefit.

Less energy consumption:

  • Our High-Performance Bioreactor reduces up to 50% of the energy cost compared to conventional systems.

Only the outside layer is Aerobic.

Anaerobic kernel, odour issues

6-10% Oxygen Utilization


Many small round flakes

Completely Aerobic, large total surface

95% Oxygen Utilization, no odour.

BIO-R-95 is made of high-quality HDPE material having at least a 20-year lifetime.

BIO-R-95 reduction of BOD/COD levels in the water prevents biofouling and will extend the lifespan of RO/UF membranes.

BIO-R-95 performance will be controlled automatically and continuously by different parameters e.g., Oxygen level, TSS, COD, pH, and Temperature.

Top quality pumps and sensors are used to guarantee a low maintenance 24 hours per day operation.

BIO-R-95 is operated and controlled fully automatic by Siemens software.

Way of working:

Based on detailed laboratory analysis of the inlet and the parameters needed to achieve after the treatment, our engineers can calculate the required dimensions of the BIO-R-95 reactors.

In case Bio-R-95 needs to be implemented in an existing treatment process our engineers prefer to do a site visit as well.

Based on this a realistic capital cost per project can be calculated and discussed with the Client.

Each installation can be activated and supported by our professional team of experienced Engineers and local partners.
