Abstract

This paper focuses on the recent research in the development of anaerobic membrane bioreactors in wastewater treatment. Anaerobic wastewater treatment technology is gaining increasing attention due to its capacity to convert wastewater BODs to usable biogas with relatively low energy consumption. The anaerobic membrane bioreactor (AnMBR), which is a combination of the anaerobic biological wastewater treatment process and membrane filtration, represents a recent development in the high-rate anaerobic bioreactors. This paper reviews applications and performances of AnMBR and the membrane filtration behaviour in AnMBRs.

Highlights

  • Environmental sustainability is one of the most critical challenges that we are currently facing

  • The efficiency of anaerobic digestion has been largely limited by the intrinsic slow growth rate of the anaerobic microorganisms, which results in a large reactor volume necessary for wastewater treatment by anaerobic digestion

  • One of the advanced solutions to improve the efficiency of anaerobic treatment is to integrate anaerobic wastewater treatment reactor with membrane filtration process to form an anaerobic membrane bioreactor system

Summary

Introduction

Environmental sustainability is one of the most critical challenges that we are currently facing. One of the advanced solutions to improve the efficiency of anaerobic treatment is to integrate anaerobic wastewater treatment reactor with membrane filtration process to form an anaerobic membrane bioreactor system. With the success of MBR technology in recent years, the large-scale membrane filtration systems have become a proved technology with effective strategies for the membrane process design, operation, and maintenance developed for the biological wastewater treatment applications. These progresses and the potential of the AnMBR as an energy recovery technology have stimulated increased research interests in AnMBRs. This paper reviews the current status and recent development
