“…Anaerobic treatment in high-rate bioreactors has increased in number of applications during municipal wastewater treatment (MWT) in the last decade while presenting an advanced technology for environmental protection and resource preservation [1,2]. The combination of membrane and an anaerobic bioreactor (Anaerobic membrane bioreactor (AnMBR)) paved the way for a sustainable wastewater treatment with complete biomass retention, and with additional advantages such as less sludge production, high quality effluent and net energy production as the organic matter is converted into high-value products (volatile fatty acids (VFAs)) and energy in the form of biogas [3,4].…”

Long term operation of an anaerobic membrane bioreactor (AnMBR) treating municipal wastewater was investigated in a real seawater intrusion spot in Falconara Marittima (Central Italy) on the Adriatic coastline. Changes in biological conversion and system stability were determined with respect to varying organic loading rate (OLR) and high salinity conditions. At an OLR of 1 kgCOD . m 3-1 d -1 , biogas production was around 0.39 ± 0.2 L . d -1 . The increase of the OLR to 2 kgCOD . m 3-1 d -1 resulted in the increase of biogas production to 2.8 ± 1.5 L . d -1 (with 33.6% ± 10.5% of CH4) with methanol addition and to 4.11 ± 3.1 L . d -1 (with 29.7% ± 11.8% of CH4) with fermented cellulosic sludge addition. COD removal by the AnMBR was 83% ± 1% when the effluent COD concentration was below 100 mg O2 . L -1 . The addition of the fermented sludge affected the membrane operation; significant fouling occurred after long-term filtration, where the trans-membrane pressure (TMP) reached up to 500 mbar. Citric acid solution was applied to remove scalants and the TMP reached the initial value. High saline conditions of 1500 mgCl -. L -1 adversely affected the biogas production without deteriorating the membrane operation. The treated effluent met the EU quality standards of the D.M. 185/2003 and the new European Commission Resolution for reuse in agriculture.

“…The slow rate of proliferation of anaerobic bacteria, especially in cold environmental conditions, requires long hydraulic residence times of the effluent in the anaerobic reactor in order to achieve the biodegradation of organic matter. Consequently, large-volume bioreactors are needed to manage large volumes of urban wastewater [4][5][6].…”

“…Another limitation is the low organic load of sewage. When the ambient temperature is around 15 °C, for the anaerobic biological activity to be effective, the chemical oxygen demand (COD) levels of the incoming effluent should be higher than 4-5 g/L [4][5][6]. This In addition, in an anaerobic membrane bioreactor (AnMBR) system treating municipal wastewater, the parameters that determine the course and performance of the biological process are the hydraulic retention time (HRT) and the sludge retention time (SRT) and organic loading rate [3].…”

“…The anaerobic treatment of municipal wastewater is based on the biological process in which certain microorganisms, in the absence of oxygen, decompose complex organic compounds into simpler ones and eventually convert them to methane (CH 4 ) and carbon dioxide (CO 2 ) [3]. The process decelerates under cold conditions and needs mesophilic or thermophilic conditions (about 35 • C or higher) for stable operation [4][5][6]. Moreover, it is not possible to generate enough biogas due to the low organic content of municipal wastewater [7].…”

Anaerobic Membrane Bioreactors for Municipal Wastewater Treatment: A Literature Review

et al. 2021

Currently, there is growing scientific interest in the development of more economic, efficient and environmentally friendly municipal wastewater treatment technologies. Laboratory and pilot-scale surveys have revealed that the anaerobic membrane bioreactor (AnMBR) is a promising alternative for municipal wastewater treatment. Anaerobic membrane bioreactor technology combines the advantages of anaerobic processes and membrane technology. Membranes retain colloidal and suspended solids and provide complete solid–liquid separation. The slow-growing anaerobic microorganisms in the bioreactor degrade the soluble organic matter, producing biogas. The low amount of produced sludge and the production of biogas makes AnMBRs favorable over conventional biological treatment technologies. However, the AnMBR is not yet fully mature and challenging issues remain. This work focuses on fundamental aspects of AnMBRs in the treatment of municipal wastewater. The important parameters for AnMBR operation, such as pH, temperature, alkalinity, volatile fatty acids, organic loading rate, hydraulic retention time and solids retention time, are discussed. Moreover, through a comprehensive literature survey of recent applications from 2009 to 2021, the current state of AnMBR technology is assessed and its limitations are highlighted. Finally, the need for further laboratory, pilot- and full-scale research is addressed.
