“…Higher average OTRs, which translate into higher average contaminant removal fluxes and treatment capacity, are usually achieved in the flow-through rather than dead-end operation (Syron & Casey 2008b). Therefore, the flow-through operation is preferred in commercial applications (Kunetz et al 2016;Peeters et al 2017aPeeters et al , 2017bUnderwood et al 2018;Guglielmi et al 2020). The higher average OTRs in flow-through MABRs can be explained by the higher oxygen partial pressure, which allows uniform intra-membrane oxygen velocities in the membrane lumens and relatively constant biofilm thickness.…”

“…(Peeters et al 2017a(Peeters et al , 2017b) used a version of the pressure-based model to account for variations in the oxygen partial pressure along the length of the MABR fiber. Guglielmi et al (2020) developed an exhaust oxygen-based model to monitor the key performance indicator OTR, which correlated with the ammonia removal rate in the biofilm. Even though both modeling methods have been used in commercial MABR applications, each is associated with biases.…”

“…However, those early reviews did not cover pilot-to full-scale experiences because MABR technology has become commercially available only recently. Commercial interest in MABRs has also grown increasingly since the launch of the first generation of commercial MABR products (Martin et al 2017;Underwood et al 2018;Guglielmi et al 2020). With three commercial MABR products available, i.e.…”

“…ZeeLung MABR by Suez Water Technologies & Solutions, OxyMem MABR by OxyMem Limited, and Fluence MABR by Fluence Corporation, global practitioners and researchers have significantly improved their understanding of the counter-diffusional biological process from the growing number of the pilot-to full-scale installations. Lu et al (2020) reviewed several pilots and full-scale MABR applications for municipal and industrial wastewater treatment, but more commercial applications are occurring for different types of wastewater treatment, and long-term operation has been investigated (Guglielmi et al 2020;Nathan et al 2020; Uri-Carreno et al 2021). This paper reviews the further accumulated knowledge and recent advances from the growing commercial installations.…”

The membrane biofilm reactor (MBfR), which is based on the counter diffusion of the electron donors and acceptors into the biofilm, represents a novel technology for wastewater treatment. When process air or oxygen is supplied, the MBfR is known as the membrane aerated biofilm reactor (MABR), which has high oxygen transfer rate and efficiency, promoting microbial growth and activity within the biofilm. Over the past few decades, lab-scale studies have helped researchers and practitioners understand the relevance of influencing factors and biological transformations in MABRs. In recent years, pilot- to full-scale installations are increasing along with process modeling. The resulting accumulated knowledge has greatly improved understanding of the counter-diffusional biological process, with new challenges and opportunities arising. Therefore, it is crucial to provide new insights by conducting this review. This paper reviews wastewater treatment advancements using MABR technology, including design and operational considerations, microbial community ecology, and process modeling. Treatment performance of pilot- to full-scale MABRs for process intensification in existing facilities is assessed. This paper also reviews other emerging applications of MABRs, including sulfur recovery, industrial wastewater, and xenobiotics bioremediation, space-based wastewater treatment, and autotrophic nitrogen removal. In conclusion, commercial applications demonstrate that MABR technology is beneficial for pollutants (COD, N, P, xenobiotics) removal, resource recovery (e.g., sulfur), and N2O mitigation. Further research is needed to increase packing density while retaining efficient external mass transfer, understand the microbial interactions occurring, address existing assumptions to improve process modeling and control, and optimize the operational conditions with site-specific considerations.

“…However, the majority of available design data to date has been obtained from facilities located in cool or temperate regions (Underwood et al 2018;Guglielmi et al 2020;Elsayed et al 2021;Uri-Carreño et al 2021), and not from Mediterranean climates as experienced in Western Australia. It has been demonstrated that MABRs are unaffected by low temperatures (Uri-Carreño et al 2021) but further investigation is required for operation in higher temperature climatic zones.…”

A 630 m3/d pilot plant was installed at Subiaco WRRF to determine design and operational parameters of a hybrid Modified Ludzack-Ettinger – Membrane Aerated Biofilm Reactor (MLE-MABR) configuration. Two commercial ZeeLung MABR cassettes were installed in series in the anoxic zone and the pilot was fed with primary effluent (averaging COD 601 mg/L, TKN 68.5 mg/L and 17–29 °C). A nitrifying biofilm was developed within 3 weeks and the nitrous oxide (N2O) gas emissions from the MABR exhaust gas proved to be a reliable parameter to assess biofilm development. Both MABRs achieved the average nitrification rate (NR) of 3.7 gNH4-N/m2.d when air flow was 8.6 and 11.2 Nm3/h to MABR1 and MABR2 respectively, which reached a maximum oxygen transfer rate of 17.4 gO2/m2.d. Biofilm thickness was controlled via air scouring and intermittent coarse bubble mixing (90 s on/90 s off). This paper discusses the startup strategy, minimum requirements for process monitoring, impact of different air flow conditions, ORP and mixing patterns on performance efficiency over a 22-week period.
