“…Expanded granular sludge bed (EGSB) was further developed to enhance substrate-biomass interaction within the treatment system by expanding the sludge bed and increasing hydraulic mixing compared to UASB (Niwa et al 2016;Cuff et al 2018). Although well-established UASB and/or EGSB configurations mostly meet the requirements necessary for anaerobic treatment, unfavourable conditions regarding the disintegration of granules led to the development of AnMBR by coupling membrane technology with anaerobic treatment.…”

The development of innovative technologies in wastewater treatment create the concept of biorefinery in wastewater treatment plants (WWTPs), placing anaerobic processes in the highlight. Starting from the conventional anaerobic treatment processes to "closing the loop" scheme, next generation WWTPs are ready to serve for water, energy and materials mining. While bioenergy is still dominating the resource recovery, recovery of value-added materials (i.e. struvite, biopolymers, cellulose) are receiving significant attention in recent years. So, what are the state-of-the-art approaches for energy-efficient resource recovery and re-use from municipal wastewater? This paper follows a critical review on the validated technologies in operational environment available and further suggests possible market routes for the recovered materials in WWTPs. Considering the development and verification of a novel technology together with the valorisation of the obtained products, biorefinery and resource recovery approaches were gathered in this review paper from a circular economy point of view. General currently-faced barriers were briefly addressed to pave the way to a create to-the-point establishments of resource recovery facilities in the future.

“…Sludge bed-based technologies, such as upflow anaerobic sludge blanket (UASB) reactors, have been widely used for MWT in full-scale WWTPs especially in tropical regions [8][9][10]. The AnMBRs, on the other hand, have been mainly applied for the treatment of high strength industrial wastewater [1,11].…”

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.

“…However, the emergence of the new FS ceramic membranes, with a predicted life at least double that of the polymeric membranes and with a purportedly higher operating flux (Niwa et al, 2016), may change the paradigm of MBR membrane selection. Since the membrane replacement component of the OPEX relates to Lm/(J t) (Section 2.2.2), the cost effective ness of a novel candidate membrane compared with the conventional one is simply determined by the ratio of Lm/(J t) for the two materials.…”

A reflection of the place cost analysis holds in membrane process technology research and development is provided. The review encompassed two membrane processes and applications: (a) reverse osmosis (RO) for seawater desalination, and (b) membrane bioreactor (MBR) technology for wastewater treatment. The cost analysis undertaken extended to (i) the determination of operating expenditure (OPEX) trends using simple analytical expressions, (ii) the subsequent estimation of the sensitivity of OPEX to individual system parameters, and (iii) published data on CAPEX for individual full-scale installations or from cost analyses. An appraisal of the peer-reviewed literature through a survey of a leading scientific database was also carried out. This bibliometric analysis was based on authors' keywords; it aimed to establish the profile of process cost for each of the two applications when compared with other popular research topics. The OPEX analysis, ostensibly through a consideration of specific energy demand in kWh per m permeate, revealed it to relate primarily to hydrodynamics in the case of RO, and to both membrane fouling and air scouring for MBRs. The bibliometric analysis of research trends revealed a marked difference in emphasis on cost aspects between the two research areas, with the focus on cost specifically being 16 times greater for RO desalination of seawater than MBR treatment of wastewater. MBR research appears to be dominated by fouling and foulant characterisation, making up almost a quarter of all studies, notwithstanding evidence from practitioners that other process parameters are as important in determining MBR process OPEX and operability.
