“…Compared to aerobic MBR, for instance Gabarró n et al reported values for total specific energy demand in a full-scale aerobic MBR reaching 1.54 kW h m −3 for flat-sheet membrane and 1.12 kW h m −3 for hollowfibre membrane [71]. Even after implementation of their energy-saving strategies involving mainly optimization of both biological aeration and membrane air-scouring, the specific energy demand reached 1.12 kW h m −3 and 0.71 kW h m −3 , respectively, regardless of similar yearly averaged hydraulic loads [71].…”

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.

“…The comparison of operation cost and energy consumption of MBR and conventional process are shown in Table 8. Energy consumption accounts for 50%-70% of MBR operation cost (Zheng et al, 2016;Meng et al, 2012;Gabarrón et al, 2014). For municipal wastewater, both operation cost and energy consumption of MBR are higher than those of conventional WWTPs.…”

During the last two decades, MBR applications in China grow exponentially with the first pilot test of 10 m/d in 1999 and the first application with capacity of 110,000 m/d commissioned in 2009. It is critical to examine the drivers of MBR applications in China, which can provide sound scientific basis for future development of MBR applications. This study summarized the historical development of MBR applications and analyzed the driving forces by survey, literature review and interviews with MBR suppliers. The results showed that: (1) technical advantages of MBR and public policy related to water resources and environment promoted MBR beyond lab and pilot test into wide commercial applications in China; (2) petrochemical industry needs for wastewater treatment and reuse promoted medium-scale MBRs as public policy and regulation on water resources and environment tightens; (3) when the breakthrough of capacity of a single project above 10 thousand m/d, the Green Olympic Games and Asian Games and tightening effluent regulations in environmentally sensitive areas incentivized MBR applications; and (4) the emergence of 100,000 m/d MBR was mainly stimulated by water resources stress. Water resources stress and public policy related on resources and the environment are the primary driving forces in the last several decades. The future drivers of MBR applications in China appear to be decreasing operation cost.

“…The authors reported energy consumption values of an MBR were in the range of 0.7-0.8 kWh m À3 (Krzeminski et al, 2012) and 0.4-0.7 kWh m À3 when operating the MBR at optimal condition in municipal facilities. Gabarron et al (2014) reported that energy consumption of a MBR using a flatsheet membrane was lower than it was when using a hollowfiber stand-alone MBR. In addition, specific organic load in industrial wastewater is higher than it is in wastewater from municipal facilities; thus, a combined process is key to reducing energy consumption.…”
