Anaerobic membrane bioreactors (AnMBRs) are increasingly being used in industrial wastewater treatment as the technology represents a cost-effective alternative to that based on aerobic processes. Not only AnMBRs are highly efficient in reducing chemical oxygen demand but the organic matter removed is transformed into a useful energy source-biogas. AnMBRs produce effluent that is free of solids and pathogens and rich in nutrients, while occupying a small footprint. As the membrane retains biomass, AnMBRs enhance performance when dealing with inhibitory or toxic substrates, typical of industrial wastewaters. Some drawbacks remain, however, including membrane fouling and its associated effects as well as poor efficiency at lower temperature (AnMBRs are usually operated at mesophilic or thermophilic conditions). Further research is needed on lowering hydraulic retention time, removal of nutrients, removal of specific micro-pollutants, establishing quantitative mass and energy/economic balances and inclusion of efficient dissolved methane recovery. In this mini review, the applications, limitations and perspectives of AnMBRs are summarized and evaluated with an emphasis on industrial wastewater treatment. Moreover, the AnMBR is compared with other wastewater treatment technologies presently available.

“…In the last 5 years, a number of fat and solid tolerant processes have emerged, including the anaerobic baffled reactor [9], the anaerobic sequencing batch reactor [10], anaerobic membrane bioreactors (AnMBR) [11,12] and the Anaerobic Flotation Reactor [13]. The AnMBR combines high rate anaerobic digestion with a membrane biomass retention system that is independent of sludge settleability [14]. AnMBRs in particular are probably the most appropriate HRAT technology suitable for slaughterhouse wastewater, particularly highstrength streams, due to excellent effluent quality, high tolerance to load variations, and ability to produce a solids free effluent for the purposes of final treatment an reuse [15].…”

membrane bioreactors enable high rate treatment of slaughterhouse wastewater, Biochemical Engineering Journal http://dx. Highlights-AnMBRs are an effective technology for treatment of slaughterhouse wastewater -COD removal was consistently over 95% and was independent of OLR and HRT -Organic loading limit of 3-3.5 gCOD.L -1 d -1 was imposed by active biomass inventory -Biomass inventory in the AnMBR was limited to 40 g.L -1 (TS) to manage fouling ABSTRACT Anaerobic Membrane Bioreactors (AnMBRs) enable high space loading by retaining solids selectively through microfiltration membranes. For organic industrial wastewaters, this offers an alternative to lagoons and granule based high-rate anaerobic treatment due to excellent effluent quality, high tolerance to load variations, and ability to produce a solids free effluent for the purposes of reuse. While there has been extensive work on low-strength and low solids effluent, there has been limited application in high-solids, high fats systems such as slaughterhouse wastewater, which are a key application. A 200L AnMBR pilot plant operated at 2 Australian cattle slaughterhouses consistently removed over 95% of chemical oxygen demand (COD) from the wastewater. Virtually all degradable COD was converted to biogas, 78-90% of nitrogen and 74% of phosphorus in the wastewater were released to the treated permeate as ammonia and phosphate respectively; which would enable subsequent nutrient capture. The mass loading rate limit of 3-3.5 gCOD.L -1 d -1 is imposed by the active biomass inventory, with this in turn limited to 40 g.L -1 (TS) by the need to manage membrane fouling control.

“…14 Research on membrane fouling during the treatment of wastewater with high concentrations of pollutants has been well documented. 15,16 In this work, the potential of MBR has been exploited for the treatment of DMAC-containing wastewater. The study set out to achieve the following goals: (1) to assess the performance of the anoxic-oxic-MBR over a range of DMAC concentrations, (2) to explore the effects of DMAC loading rates on membrane fouling, and (3) to study the degradation mechanism of DMAC based on the identication of catabolic intermediates.…”
