Abstract
Over the past 45 years, anaerobic membrane bioreactor (AnMBR) technology has transitioned from laboratory-scale research to widespread successful implementation in various wastewater treatment applications, as part of sustainable technology initiatives. Compared to aerobic membrane bioreactor (AeMBR) and conventional anaerobic treatment methods, AnMBR offers numerous well-documented advantages, including efficient reduction of chemical oxygen demand (COD), conversion of organic waste into useful biogas, and production of treated effluent with less sludge generation. Nevertheless, employing AnMBR for treating low to moderate strength wastewater, such as domestic and municipal wastewater, continues to pose challenges due to concerns regarding membrane fouling and low bioenergy recovery efficiency. This article features last 11 year’s publication statistics to visualize global research trends covering the historical development of AnMBRs and related areas, emphasizing key innovations and technological milestones that have driven their evolution in reactor configurations. It includes a performance comparison of AnMBRs across different wastewater treatments, presenting a tabulated analysis and critically discussed various performance parameters such as, COD removal efficiency, biogas production, biomass retention, and sludge generation. The discussion also covered the impact of operational and design parameters on AnMBR performance to enhance the depth of analysis. Despite its effectiveness, AnMBR frequently suffers from substantial membrane fouling and low degradation rate. While addressing such issues, this article also explores both conventional and modified approaches, including the use of bioelectrochemical techniques for fouling control and enhanced methane recovery. Finally, this paper highlights a comprehensive overview and identifies potential areas for future research pertaining to the prevailing issues.
