Performance and Microbial Community Structure of Anaerobic Membrane Bioreactor for Lipids-Rich Kitchen Waste Slurry Treatment: Mesophilic and Thermophilic Processes

“…The system recovered and microbial diversity was starting to pick up. The Gannoun and Tow's researches [37,41] also found the same results, i.e., the dynamic changes in community diversity were due to the selective pressures in this environment. These results showed that the digestion performance and stability of the reactor were closely related to microbial diversity.…”

“…Based on the OTU results as described in Section 2.5, the alpha diversity and beta diversity were compared between mesophilic and thermophilic digestion. The Shannon index and principal component analysis (PCA) were the most recognized indicators to evaluate the alpha and beta diversity, respectively [37,38]. Table 3 showed the Shannon variation of M1, M2, T1, T2, T3, R1, R2, T3, T4 and T5 under different operation stages.…”

Slaughterhouse wastewater characteristics, treatment, and management in the meat processing industry: A review on trends and advances

“…The performance of up-flow anaerobic filters (UAFs) has been examined under thermophilic and mesophilic conditions for SWW treatment (Gannoun et al, 2009(Gannoun et al, , 2013. The results showed that COD removal efficiencies of up to 90% can be achieved for organic loading rates (OLRs) of 9000 mg/L day under mesophilic conditions and 72% under thermophilic conditions.…”

Effect of Seasonal Temperature on the Performance and on the Microbial Community of a Novel AWFR for Decentralized Domestic Wastewater Pretreatment

“…Despite the effective chemical oxygen demand (COD) removal by these anaerobic biotechnologies, some challenges still exist, such as complex three-phase separator and long solids' retention time of UASB, membrane fouling and high energy costs of AnMBR, and high land footprint of ABR. Compared to these high-rate anaerobic reactors, the anaerobic filters (AFs) have drawn attention because of the following advantages [13][14][15]: (1) simple design configuration with low capital and operating costs, (2) excellent capability of high biomass retention with carriers, (3) stable operation, (4) greater tolerance to hydraulic loading rate and organic loading rate, and (5) low footprint. The potential of using AFs for treating wastewater have been well developed not only for industrial wastewater, but also for domestic wastewater [5,[16][17][18].…”
