Combining Thermophilic Aerobic Reactor (TAR) with Mesophilic Anaerobic digestion (MAD) to improve sludge reduction and pharmaceuticals degradation

Résumé

A combination of thermophilic aerobic reactor (TAR) with mesophilic anaerobic digestion (MAD) was evaluated for its capacity to enhance the sludge reduction, increase the methane production and improve the efficiency of micropollutant biodegradation when applied to a primary sludge obtained after decantation of urban wastewater. Higher elimination of organic matter was achieved in MAD-TAR (76% for VSS) compared to conventional MAD (47%). Nevertheless, the measured methane production was comparable for the two processes showing either a contribution of micro-aerobic degradation or a loss of diluted methane in the gas flow. The removal efficiency of pharmaceutical compounds obtained in the two configurations was compared. The highest removal rates were reported for caffeine (CAF) and sulfamethoxazole (SMX) (>89%) with no significant differences between both processes. MAD-TAR increased significantly the removal for oxazepam (OXA) (73%), propranolol (PRO) (61%) and ofloxacine OFL (41%) and slightly for diclofenac (DIC) (4%) and 2 hydroxy-ibuprofen (2OH-IBP) (5%).
