Four key targets

Carbon savings


  • To decrease the residence time of the sludge (sludge age) and increase the organic loading rate of the aerobic treatment.
  • To reduce the need for aeration in the aerobic treatment generating significant energy saving and thus reducing the carbon footprint of the aerobic wastewater treatment.
  • To generate biosludge to be used as a substrate for biogas production. The biosludge can be digested as a single substrate or co-digested with other onsite or offsite substrates.
  • To further reduce the overall carbon footprint of the wastewater treatment by replacing commercial nitrogen and phosphorus addition by rejected water (post anaerobic digestion) recirculation.

*this value assumes the replacement of petrol/diesel fuels with biogas. It is based on the RED - Renewable Energy Directive - approach for carbon savings. No EffiSludge impacts on wastewater treatment operation are included yet.
