An anaerobic membrane bioreactor (AnMBR) combines anaerobic processes and membrane filtration. Compared to the aerobic membrane reactor less energy is needed because the reactor does not need to be aerated.During treatment, anaerobic processes convert biodegradable organic compounds into biogas. Most of the nutrients stay in the liquid effluent as ammonium and phosphate, available for subsequent recovery.

Because of the filtration, the effluent is free of suspended solids and pathogens. The nutrient rich and pathogen free effluent can directly be reused in agriculture for fertigation (depending on local legislation).

In Run4Life, the AnMBR is used in demosite Vigo.
