The current application of AnMBR is limited due to a variety of technical issues, limited product recovery, and energy intensive operation. The conventional design of the AnMBR is currently unable to remove a wide range of emerging pollutants and nutrients from waste streams. Additionally, the major AnMBR product-methane-has been identified as endangering the environment. In most AnMBR systems, the energy recovered from producing methane has not exceeded the energy requirement of the AnMBR. However, more recent developments in this field have improved the overall performance and energy efficiency significantly. The most recent developments include design modifications, integration of physical/chemical separation processes, and bioelectrochemical systems (BES) in comparison to the traditional single-stage design. Research on controlling membrane fouling has also contributed to improvements in the performance of AnMBRs.
