BACKGROUND Fly ash is an important source of trace elements that can act as cofactors of enzyme systems and improve anaerobic digestion processes. However, its effect on anaerobic digestion using real wastewater has not yet been studied. In the present work, the effect of fly ash on the anaerobic digestion of real winery wastewaters was studied, by means of specific methanogenic activity assays and with a special focus on its effect on the specific methane production and the microbial communities present. Five fly ash concentration (25, 50, 75, 100, and 150 mg L−1) were supplemented under mesophilic conditions. RESULTS The results showed that 25 mg L−1 of fly ash improved the specific methane production by 18% compared to the control assay; meanwhile, a concentration of 100 mg L−1 of fly ash generated inhibition of the methanogenesis and a 20% specific methane production decrease with respect to the control experiment. The microbial community analysis verified that fly ash supplementation affected the bacterial communities, with a significant effect on acetogenic bacteria, such as Cloacimonetes and Firmicutes. CONCLUSION The addition of adequate concentrations of fly ash to the process can raise the relative abundance of some microorganisms and, consequently, could increase the specific methane production in the anaerobic digestion of winery wastewater. © 2021 Society of Chemical Industry (SCI).

“…The UASB technology has also been widely used for high-strength wastewater achieving stable operation due to high anaerobic reaction rates combined with limited sensitivity to fluctuating parameters (e.g., acidity, HRT) [ EGSB is a modified UASB version, developed to attain higher upflow velocities and accommodate more variable loading rates under a lower footprint [46,48]. The higher upflow velocity increases the granular sludge bed fluidization, which, subsequently, improves the contact between wastewater and sludge [47].…”

Industrial wastewater contains complex and slowly biodegradable compounds often ineffectively treated by conventional activated sludge (CAS) systems. Alternatively, advanced anaerobic technologies are implemented. The current study reviews different potential anaerobic schemes, factors influencing their final performance and optimum combinations of operational/design parameters. Anaerobic membrane bioreactors, upflow anaerobic sludge blanket reactors, expanded granular sludge beds, anaerobic hybrid reactors and inverse fluidized bed reactors are discussed. Their major advantages include: low energy requirements, energy recovery through biogas generation and high organic load removal. pH~7, operation in a mesophilic environment and a hydraulic retention time long enough to enable anaerobic digestion in economically accepted reactor volumes are conditions that optimize the performance of anaerobic configurations. The evaluation additionally considers environmental aspects. The life cycle assessment of anaerobic industrial wastewater treatment reveals its positive environmental effect in terms of greenhouse gases emissions. Methane (a greenhouse gas) primarily contained in the biogas, despite being produced during anaerobic digestion, is utilized for energy production (heating, electricity) instead of being emitted to the atmosphere. Finally, anaerobic wastewater treatment is analyzed as part of the European Commission Innovation Deal that aims at converting conventional wastewater treatment plants to water resource recovery facilities able to combine sustainable wastewater treatment and water reuse. Response to Reviewers: Reviewer #1: The topic and the results of the current study are generally very

“…Even though aerobic degradation is a fast way to remove DEHP, it is also energy intensive. Compared with aerobic degradation, anaerobic treatment provides many benefits, including lower energy requirements, methane generation, and lower biological sludge production (Petropoulos et al, 2016). Therefore, further study should be conducted to improve the efficiency of the anaerobic degradation of DEHP.…”

Recently, the endocrine-disrupting and carcinogenic compound di-(2-ethylhexyl) phthalate (DEHP) has gained increased attention. In this study, the enhanced effect of cometabolism on DEHP removal and the associated microbial processes in an extended granular sludge bed (EGSB) reactor over 293 days were investigated. The results indicated that it took 181 days to start up the reactor, with only a 38.5% removal efficiency when treating 0.6 mg/L DEHP wastewater. The addition of glucose at low concentrations (1 and 2 g/L) promoted DEHP removal. However, higher concentrations (5 and 10 g/L) inhibited the bioprocess. In contrast, yeast enhanced DEHP degradation at all of the tested concentrations (0.1, 0.2, 0.3, and 0.4 g/L). Quantitative real-time PCR (q-PCR) and statistical analysis demonstrated that the amount of the archaea and DEHP removal were positively correlated (r = 0.99, p < 0.05). A MiSeq sequencing analysis revealed that the microbial community had an obvious shift that accompanied the increasing DEHP removal rate. Bacteroidetes and Firmicutes maintained a relatively constant abundance during the entire trial, while Spirochetes and d-Proteobacteria gradually became predominate in the EGSB reactor. At the genus level, the relative abundance of Levilinea, Thauera, and Actinobaculum gradually decreased. For the archaea, the acetoclastic methanogens, Methanosaeta and Methanosarcina, existed in the EGSB reactor throughout the experiment. This study suggests that cometabolism is feasible for enhancing DEHP wastewater treatment, and it shows the potential for practical applications in engineering.
