“…Membrane-based wastewater treatment processes have proven to be a significant improvement from conventional treatment systems in reducing biotic contaminants, and thus making progress towards reuse without disinfection and DBPs [40]. Anaerobic digestion has also been shown to be an effective way at reducing the burden of pathogens in waste treatment [41].…”

Broad and increasing interest in sustainable wastewater treatment has led a paradigm shift towards more efficient means of treatment system operation. A key aspect of improving overall sustainability is the potential for direct wastewater effluent reuse. Anaerobic membrane bioreactors (AnMBRs) have been identified as an attractive option for producing high quality and nutrient-rich effluents during the treatment of municipal wastewaters. The introduction of direct effluent reuse does, however, raise several safety concerns related to its application. Among those concerns are the microbial threats associated with pathogenic bacteria as well as the emerging issues associated with antibiotic-resistant bacteria and the potential for proliferation of antibiotic resistance genes. Although there is substantial research evaluating these topics from the perspectives of anaerobic digestion and membrane bioreactors separately, little is known regarding how AnMBR systems can contribute to pathogen and antibiotic resistance removal and propagation in wastewater effluents. The aim of this review is to provide a current assessment of existing literature on anaerobic and membrane-based treatment systems as they relate to these microbial safety issues and utilize this assessment to identify areas of potential future research to evaluate the suitability of AnMBRs for direct effluent reuse.

“…In studies reviewed by Hai et al (2014), almost complete removal of bacteria by membrane bioreactors (MBR) was reported, whereas virus removal was inconsistent. Even though Campylobacter was not mentioned, it is presumable that a well-functioning MBR system is efficient in removing Campylobacter.…”

“…One study in this Special Issue showed that well designed and operated membrane bioreactors (MBRs) can consistently achieve efficient removals of TSS and pathogens. Hai et al [20] provide an in-depth overview of the mechanisms and influencing factors of pathogen removal by MBRs and highlight practical issues, such as reduced chemical disinfectant dosing requirements and associated economic and environmental benefits. Additional operational aspects, such as membrane cleaning, membrane imperfections/breach and microbial regrowth in the distribution system are also discussed.…”
