“…In recent years, several studies have investigated the application of anaerobic digestion in order to revalue the brewery wastes [11][12][13][14] . Anaerobic digestion (AD) is used worldwide for the treatment of agro-industrial streams and sewage sludge from wastewater treatment plants, and contributes efficiently in solid waste reduction and biogas production 15 . The production and use of biogas generated by the AD process represents significant potential to achieve energy-related, environmental, and economic benefits 16 .…”

In the food industry, the brewing sector holds a strategic economic position: in the year 2013, the beer production of the EU-28 was equal to 383,553,000 hL. The brewing process includes chemical and biochemical reactions and solid-liquid separations, involving the generation of various residues and by-products, among which the major two fractions are brewer's spent grain (BSG), and exhausted brewery yeast (BY). Although until today their main use has been for animal feed, in recent years, several studies have investigated the application of anaerobic digestion in order to revalue the brewery wastes.In this work, specific methane production (SMP) and first-order solubilisation (disintegration + hydrolysis) rates (k sol ) for BSG and BY were evaluated. Biomethanation tests were performed in 5-L fed-batch stirred reactors at several substrate/inoculum ratios.

“…Disintegration is a physical process and the rest four biochemical processes are catalyzed by intra-or extracellular enzymes. The ADM1 model has been implemented to simulate AD of different industrial wastes and proved to be successful (Derbal et al, 2009;Ozkan-Yucel and Gokcay, 2010). Some extensions of the ADM1 were also established to account for the effects of micro-oxygen (Botheju et al, 2010), the degradation of phenolic compounds (Fezzani and Cheikh, 2009), and the formation and emission of odorants (Parker and Wu, 2006).…”

Anaerobic digestion model No.1 (ADM1) was applied and expanded in this study to model and simulate anaerobic digestion (AD) of an industrial carbon capture reclaimer MEA (monoethanolamine) waste (MEAw) together with easily degradable organics. The general structure of ADM1 was not changed except for introducing state variables of MEA and complex organics (CO) in the waste and biochemical reactions of MEA uptake and CO hydrolysis in the model ADM1 MEAw. Experimental batch test results were used for calibrating kinetics variables. The obtained kinetics were employed in the ADM1 MEAw to simulate semi-continuously fed experimental test for 486 days at room temperature (22 ± 2 o C). The validation results show that the ADM1 MEAw was able to predict the process performance with reasonable accuracy, including process pH, biogas generation and inorganic nitrogen concentrations, for a wide range of feed scenarios. Free ammonia inhibition, was observed to be the main inhibitory effects on acetoclastic methanogenesis, leading to volatile fatty acids (VFA) accumulation at high loads. Inhibition assumed to be caused by potentially toxic constituents of MEAw appears to be much less important than ammonia, suggesting that such constituents were broken down by AD.

The Objective of this paper is to present the application of the Modified ADM1 model to simulate the dynamic behaviour of a two-stage anaerobic treatment process treating the wastewater generated from the ethanol distillery process. The laboratory-scale process comprised an anaerobic continuous stirred tank reactor (CSTR) and an upflow anaerobic sludge blanket (UASB) connecting in series, was used to treat wastewater from the ethanol distillery process. The CSTR and UASB hydraulic retention times (HRT) were 12 and 70 hours, respectively. The model was developed based on ADM1 basic structure and implemented with the simulation software AQUASIM. The simulated results were compared with measured data obtained from using the laboratory-scale two-stage anaerobic treatment process to treat wastewater. The sensitivity analysis identified maximum specific uptake rate (k m ) and half-saturation constant (K s ) of acetate degrader and sulfate reducing bacteria as the kinetic parameters which highly affected the process behaviour, which were further estimated. The study concluded that the model could predict the dynamic behaviour of a two-stage anaerobic treatment process treating the ethanol distillery process wastewater with varying strength of influents with reasonable accuracy.
