A New Membrane-Aerated Biofilm Reactor for Low Energy Wastewater Treatment: Pilot Results
Abstract
A new hybrid membrane-aerated biofilm reactor (MABR) technology that enables energy-neutral treatment of municipal wastewater is introduced. The process, which removes nitrogen using conventional nitrification-denitrification, was demonstrated at pilot-scale, treating primary effluent. The new MABR membrane product can operate in a high mixed liquor suspended solids (MLSS) environment, making it suitable for use in a conventional activated sludge reactor to increase oxygen transfer and nitrification capacity. The pilot achieved removal rates of 91% for TSS, 83% for COD, 95% for ammonia, and 66% for total inorganic nitrogen. MABR technology has the potential to transfer oxygen very efficiently, at an aeration efficiency of 6 kg O2/kWh.
