Abstract/Contents

Abstract: Current work at the Colorado School of Mines investigates a coupled hybrid anaerobic reactor for the generation of energy (CHARGE) system for the anaerobic treatment of wastewater at pilot scale. The hybrid anaerobic reactor (total system volume of 2.8 m3), consisting of three equally sized compartments operating as an anaerobic baffled reactor (ABR) followed by a smaller anaerobic fixed film reactor (AFFR) compartment, has treated municipal wastewater from a 250-unit apartment complex in continuous operation for approximately 900 days. Effluent quality has approached EPA secondary standards for TSS (30mg/L) during warmer temperatures (22-24 ̊C). While the ABR-AFFR (total system volume of 2.8 m3) removes more than 70% of influent tCOD and converts a majority of the influent organic matter to methane and carbon dioxide, it does not remove nutrients. A partially anaerobic mode of nitrogen removal has the potential to significantly reduce the cost and energy consumption relative to conventional methods of nitrification and denitrification. The novel method couples partial nitritation with fixed-film anaerobic ammonium oxidation (anammox) in a hybrid moving bed biofilm reactor (HMBBR) (Figure 1). The integration of anaerobic organic removal with simultaneous partial-nitritation anammox (PN/A) has the potential to revolutionize mainstream wastewater treatment.
