“…Additionally, the mixed liquor has poor filterability as a result of the SMP quickly building up in the MBR due to membrane rejection. Furthermore, the polysaccharide in SMP contributes more to membrane fouling than protein 67 . Fu et al 68 also said that the reduced EPS concentration, specifically lower polysaccharide concentrations, may be the primary cause of the improved filtration performance that was attained in the MB-MBR process as compared to traditional MBR.…”

Although submerged membrane bioreactor (MBR) are widely used in treating municipal wastewater and recovery of potential resources, membrane operational parameters and membrane fouling control remain debated issues. In this study, the treatment of municipal wastewater by MBR at high-biomass sludge (MLSS (g/L) ranging from 5.4 g/L to 16.1 g/L) was assessed at an organic loading rates (OLRs) ranging from 0.86 to 3.7 kg COD/m3d. The correlation between trans-membrane pressure and total fouling resistance was thoroughly investigated in this study. According to the findings, greater OLRs of 0.86 to 3.7 kg COD/m3d caused a decrease in COD, BOD, and NH4–N removal efficiency, and higher OLRs of 3.7 kg COD/m3d resulted in a higher increase in total fouling resistance (Rt). The economic study of using the MBR system proved that for a designed flow rate of 20 m3/d, the payback period from using the treated wastewater will be 7.98 years, which confirms the economic benefits of using this MBR for treating municipal wastewater. In general, understanding the challenges facing the efficiency of MBR would improve its performance and, consequently, the sustainability of wastewater reclamation.

“…The MBBR system has a removal efficiency of 90% for COD when compared to an activated sludge process for tannery effluent (Goswami and Mazumdar 2016). When it comes to textile wastewater, efficiency as high as 98.5% was achieved (Erkan et al 2020).…”

Last two decades have brought commendable respect for biofilm processes in wastewater treatment. Preeminent components from both the biofilter processes and activated sludge are utilized in evolving the moving bed process which eliminates major pollutants, organic matter and nutrients from municipal as well as industrial wastewater. The present review work is an endeavor to focus on the moving bed biofilm process for wastewater treatment applied in different aspects. An overview of MBBR development along with the factors affecting the operational performance of the system is discussed. It also analyses and investigates the state of the art of MBBR process for organic matter and nutrient removal. The review further assesses the MBBR technology as a hybrid system with current findings. Furthermore, the scope for future research prospects and challenges of the moving bed process has been discussed.

“…The factors responsible for fouling could be properties of mixed liquor suspended solids (MLSS), characteristics of the membrane, and operating conditions such as hydraulic retention time (HRT), solids retention time (SRT), and aeration intensity. The fouling of the membrane could affect the effluent quality and increase the operational cost by up to 60% (Sari Erkan et al, 2020). Additionally, membrane fouling necessitates frequent membrane cleaning and shortens the membrane life span, followed by the replacement of the membrane (Krzeminski et al, 2017).…”

“…A membrane bioreactor (MBR) is a promising technology for the treatment of wastewater by combining the membrane process with biological treatment (Sari Erkan et al, 2020; Teng et al, 2020). MBRs attain biomass retention by providing direct solid–liquid separation through the use of membrane filtration using microfiltration (MF) or ultrafiltration (UF) membranes (Diez et al, 2014).…”

Membrane technology offers a wide variety of advantages in wastewater treatment, but fouling impedes its widespread applications. Hence, in this study, a novel method was tried to control membrane fouling by combining the self‐forming dynamic membrane (SFDM) with a sponge‐wrapped membrane bioreactor. The configuration is termed a “Novel‐membrane bioreactor” (Novel‐MBR). To compare the performance of Novel‐MBR, a conventional membrane bioreactor (CMBR) was operated under similar operating conditions. CMBR and Novel‐MBR were run consequently for 60 and 150 days, respectively. The Novel‐MBR was composed of SFDMs in two compartments before a sponge‐wrapped membrane in the membrane compartment. In Novel‐MBR, the formation times for SFDMs on coarse (125 μm) and fine (37 μm) pore cloth filers were 43 and 13 min, respectively. The CMBR experienced more frequent fouling; the maximum fouling rate was 5.83 kPa/day. In CMBR, the membrane fouling due to cake layer resistance (6.92 × 1012 m−1) was high, and that alone contributed to 84% of fouling. In Novel‐MBR, the fouling rate was 0.0266 kPa/day, and the cake layer resistance was 0.329 × 1012 m−1. Also, the Novel‐MBR experienced 21 times less reversible fouling and 36 times less irreversible fouling resistance than the CMBR. In Novel‐MBR, the formed SFDM and the sponge wrapped on the membrane helped to reduce both reversible and irreversible fouling. With the modification tried in the present study, the Novel‐MBR experienced less fouling, and the maximum transmembrane pressure at the end of 150 days of operation was 4 kPa. Practitioner Points CMBR experienced frequent fouling, and the maximum fouling rate was 5.83 kPa/day. Cake layer resistance was dominant in CMBR and contributed to 84% of fouling. The fouling rate of Novel‐MBR at the end of the operation was 0.0266 kPa/day. Novel‐MBR is expected to perform for ≈3380 days to reach the maximum TMP of 35 kPa.
