“…In contrast, batch experiments using sludge from the same plant showed no significant removal of primidone over 48 h. The authors concluded that the sludge may have lost its ability to transform primidone. Less than 2% removal efficiency was obtained for primidone at an initial concentration of 1.7 mg/L from a wastewater treated in an anaerobic membrane bioreactor (Monsalvo et al, 2014).…”

“…A small footprint, complete solid-liquid separation, high volumetric organic removal rate, and higher effluent quality are some of the key advantages of the MBR and AnMBR [20,[64][65][66]. In the submerged hollow fiber MBR, the membranes are directly immersed in the aeration tank.…”

Abstract:The submerged membrane filtration concept is well-established for low-pressure microfiltration (MF) and ultrafiltration (UF) applications in the water industry, and has become a mainstream technology for surface-water treatment, pretreatment prior to reverse osmosis (RO), and membrane bioreactors (MBRs). Compared to submerged flat sheet (FS) membranes, submerged hollow fiber (HF) membranes are more common due to their advantages of higher packing density, the ability to induce movement by mechanisms such as bubbling, and the feasibility of backwashing. In view of the importance of submerged HF processes, this review aims to provide a comprehensive landscape of the current state-of-the-art systems, to serve as a guide for further improvements in submerged HF membranes and their applications. The topics covered include recent developments in submerged hollow fiber membrane systems, the challenges and developments in fouling-control methods, and treatment protocols for membrane permeability recovery. The highlighted research opportunities include optimizing the various means to manipulate the hydrodynamics for fouling mitigation, developing online monitoring devices, and extending the submerged HF concept beyond filtration.

“…Alternatively, AnMBRs require little to no sludge wasting as part of the anaerobic digestion process, effectively eliminating the possibility of long-term OMP removal by biosolids sorption. As a result, AnMBRs have been observed to rely on biodegradation as opposed to sorption as the primary mechanism for OMP removal from wastewaters [25,26]. This difference in removal mechanisms can be attributed to the overall better biodegradability of OMPs, and specifically antibiotics, under anaerobic digestion conditions as compared to aerobic [27,28].…”

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.
