The activated sludge (AS) is most commonly used treatment technology today at water resource recovery facilities (WRRFs) around the world. Some of the WRRFs are being upgraded to meet the requirements for water reuse and/or capacity expansion. WRRFs often employ membrane bioreactor (MBR) and/or moving bed biofilm reactors (MBBR) to achieve these goals respectively. However, MBR/MBBR technologies are expensive and energy intensive. The goal of this biomembrane filtration process is to dramatically reduce the required energy and cost to produce treated wastewater for reuse if desired. A pilot-scale membrane aerated biofilm reactor (MABR) is being developed for nitrification at Ann Arbor Wastewater Treatment Plant.
