Aerobic membrane bioreactors (MBRs) are one of the leading technologies to achieve sustainability in wastewater treatment through reuse, decentralization, and low energy consumption (Fane and Fane 2005; Fawehinmi et al. 2005). In aerobic MBRs, aerated activated sludge is coupled with membrane process to remove dissolved contaminants (carbon and ammonia) and separate solids from the treated municipal or industrial wastewater. Carbon is removed by microorganisms that metabolize the carbon in the presence of dissolved oxygen for microbial growth and respiration (organic carbon reduced to carbon dioxide). Ammonia is removed through ammonia oxidation (nitrification). Nitrification is a microbially mitigated reduction process that occurs in an aquatic environment that contains moderate to high concentrations of...
