Human urine has a high chemical oxygen demand (COD) content which makes anaerobic treatments potentially appropriate for the management of yellow waters, allowing for energy recovery. However, its high N content makes this treatment challenging. The present work studied the viability of performing an anaerobic digestion process for COD valorization on a real (not synthetic) urine stream at laboratory scale.

- A 350-day study evaluated a demonstration plant using anaerobic membrane bioreactor (AnMBR) technology to treat urban wastewater at temperatures between 25-30 °C.
- The plant processed effluent from a municipal wastewater treatment facility, achieving up to 87% biodegradability and exceeding 90% removal of chemical oxygen demand (COD) while keeping effluent COD within acceptable limits.
- The operation led to a significant reduction in sludge production and maintained effective membrane performance for over 250 days without needing chemical cleaning, indicating the potential for energy efficiency and low greenhouse gas emissions in warmer climates.
